How to pretty print JSON string using Jackson?

By Wayan Saryada in Jackson 4 Comments

The following example demonstrates how to pretty print the JSON string produces by Jackson library. To produce well formatted JSON string we create the ObjectMapper instance and enable the SerializationFeature.INDENT_OUTPUT feature. To enable this feature we need to call the enable() method of the ObjectMapper and provide the feature to be enabled.

ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
String json = mapper.writeValueAsString(recording);
System.out.println(json);

On the second example below we format unformatted JSON string. To do this we use the ObjectMapper‘s readValue(String, Class<T>) method which accept the JSON string and Object.class as the value type. The readValue() method return an Object. To format the JSON object we call mapper.writerWithDefaultPrettyPrinter().writeValueAsString(Object). This will produce a pretty formatted JSON.

ObjectMapper mapper = new ObjectMapper();
Object jsonObject = mapper.readValue(json, Object.class);
String prettyJson = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(jsonObject);
System.out.println(prettyJson);

Below is the complete code snippets.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

import java.io.IOException;
import java.time.LocalDate;
import java.time.Month;

public class JsonIndentOutput {
    public static void main(String[] args) {
        JsonIndentOutput.formatObjectToJsonString();
        JsonIndentOutput.formatJsonString();
    }

    private static void formatObjectToJsonString() {
        Recording recording = new Recording();
        recording.setId(1L);
        recording.setTitle("Yellow Submarine");
        recording.setReleaseDate(LocalDate.of(1969, Month.JANUARY, 17));
        recording.setArtist(new Artist(1L, "The Beatles"));
        recording.setLabel(new Label(1L, "Apple"));

        ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
        try {
            String json = mapper.writeValueAsString(recording);
            System.out.println(json);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }

    private static void formatJsonString() {
        String json = "{\"id\":1,\"title\":\"Yellow Submarine\",\"releaseDate\":\"1969-01-17\",\"artist\":{\"id\":1,\"name\":\"The Beatles\"},\"label\":{\"id\":1,\"name\":\"Apple\"}}";
        ObjectMapper mapper = new ObjectMapper();
        try {
            Object jsonObject = mapper.readValue(json, Object.class);
            String prettyJson = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(jsonObject);
            System.out.println(prettyJson);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

The code snippet above will pretty print the following JSON string:

{
  "id" : 1,
  "title" : "Yellow Submarine",
  "releaseDate" : "1969-01-17",
  "artist" : {
    "id" : 1,
    "name" : "The Beatles"
  },
  "label" : {
    "id" : 1,
    "name" : "Apple"
  }
}

Here are the structure of Recording class.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;

import java.time.LocalDate;
import java.util.Objects;

public class Recording {
    private Long id;
    private String title;

    @JsonDeserialize(using = LocalDateDeserializer.class)
    @JsonSerialize(using = LocalDateSerializer.class)
    private LocalDate releaseDate;

    private Artist artist;
    private Label label;

    public Recording() {
    }

    public Recording(Long id, String title, LocalDate releaseDate) {
        this.id = id;
        this.title = title;
        this.releaseDate = releaseDate;
    }

    // Getters and Setters
}

How to convert java.time.LocalDate to java.util.Date?

By Wayan Saryada in Date Time 2 Comments

The following code snippet demonstrate how to convert java.time.LocalDate to java.util.Date and vice versa. In the first part of the code snippet we convert LocalDate to Date and back to LocalDate object. On the second part we convert LocalDateTime to Date and back to LocalDateTime object.

package org.kodejava.example.datetime;

import java.time.*;
import java.util.Date;

public class LocalDateToDate {
    public static void main(String[] args) {
        // Convert java.time.LocalDate to java.util.Date and back to
        // java.time.LocalDate
        LocalDate localDate = LocalDate.now();
        System.out.println("LocalDate = " + localDate);

        Date date1 = Date.from(localDate.atStartOfDay(ZoneId.systemDefault()).toInstant());
        System.out.println("Date      = " + date1);

        localDate = date1.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
        System.out.println("LocalDate = " + localDate);
        System.out.println();

        // Convert java.time.LocalDateTime to java.util.Date and back to
        // java.time.LocalDateTime
        LocalDateTime localDateTime = LocalDateTime.now();
        System.out.println("LocalDateTime = " + localDateTime);

        Date date2 = Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());
        System.out.println("Date          = " + date2);

        localDateTime = date2.toInstant().atZone(ZoneId.systemDefault()).toLocalDateTime();
        System.out.println("LocalDateTime = " + localDateTime);
    }
}

The result of the code snippet:

LocalDate = 2017-02-14
Date      = Tue Feb 14 00:00:00 WITA 2017
LocalDate = 2017-02-14

LocalDateTime = 2017-02-14T10:34:49.562
Date          = Tue Feb 14 10:34:49 WITA 2017
LocalDateTime = 2017-02-14T10:34:49.562

How to format LocalDate object using Jackson?

By Wayan Saryada in Jackson 4 Comments

We have a Recording class which has a Java 8 java.time.LocalDate property. We need to deserialize and serialize this property from and to JSON string. To do this we can use the @JsonDeserialize and @JsonSerialize annotations to annotate the LocalDate property of the Recording class.

@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
private LocalDate releaseDate;

To use the annotation we need to create a class to deserialize and serialize the value. To create a deserializer class we create a class that extends StdDeserializer. The serializer class extends the StdSerializer class. Below is the definition of the LocalDateSerializer and LocalDateDeserializer class.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.fasterxml.jackson.databind.ser.std.StdSerializer;

import java.io.IOException;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class LocalDateSerializer extends StdSerializer<LocalDate> {

    public LocalDateSerializer() {
        super(LocalDate.class);
    }

    @Override
    public void serialize(LocalDate value, JsonGenerator generator, SerializerProvider provider) throws IOException {
        generator.writeString(value.format(DateTimeFormatter.ISO_LOCAL_DATE));
    }
}

package org.kodejava.example.jackson;

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.deser.std.StdDeserializer;

import java.io.IOException;
import java.time.LocalDate;

public class LocalDateDeserializer extends StdDeserializer<LocalDate> {

    protected LocalDateDeserializer() {
        super(LocalDate.class);
    }

    @Override
    public LocalDate deserialize(JsonParser parser, DeserializationContext context) throws IOException {
        return LocalDate.parse(parser.readValueAs(String.class));
    }
}

Let’s create a simple class that convert Recording object into JSON string and apply the date formatter defined in the LocalDateSerializer class.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

import java.time.LocalDate;
import java.time.Month;

public class RecordingToJson {
    public static void main(String[] args) {
        Recording recording = new Recording();
        recording.setId(1L);
        recording.setTitle("Twist and Shout");
        recording.setReleaseDate(LocalDate.of(1964, Month.FEBRUARY, 3));

        ObjectMapper mapper = new ObjectMapper();
        try {
            String json = mapper.writeValueAsString(recording);
            System.out.println("JSON = " + json);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }

    }
}

The output of the code snippet above is:

JSON = {"id":1,"title":"Twist and Shout","releaseDate":"1964-02-03","artist":null,"label":null}

And here is the complete definition of the Recording class.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;

import java.time.LocalDate;
import java.util.Objects;

public class Recording {
    private Long id;
    private String title;

    @JsonDeserialize(using = LocalDateDeserializer.class)
    @JsonSerialize(using = LocalDateSerializer.class)
    private LocalDate releaseDate;

    private Artist artist;
    private Label label;

    public Recording() {
    }

    public Recording(Long id, String title, LocalDate releaseDate) {
        this.id = id;
        this.title = title;
        this.releaseDate = releaseDate;
    }

    // Getters and Setters
}

How to read and write Java object to JSON file?

By Wayan Saryada in Jackson 0 Comment

The following example demonstrate how to serialize and deserialize Java object to JSON file. The Jackson’s ObjectMapper class provides writeValue(File, Object) and readValue(File, Class<T>) methods which allow us to write an object into JSON file and read JSON file into an object respectively.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.databind.ObjectMapper;

import java.io.File;
import java.io.IOException;

public class ObjectToJsonFile {
    public static void main(String[] args) {
        Artist artist = new Artist();
        artist.setId(1L);
        artist.setName("The Beatles");

        ObjectMapper mapper = new ObjectMapper();

        File file = new File("artist.json");
        try {
            // Serialize Java object info JSON file.
            mapper.writeValue(file, artist);
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            // Deserialize JSON file into Java object.
            Artist newArtist = mapper.readValue(file, Artist.class);
            System.out.println("newArtist.getId() = " + newArtist.getId());
            System.out.println("newArtist.getName() = " + newArtist.getName());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

The result of the code snippet are:

newArtist.getId() = 1
newArtist.getName() = The Beatles

How to convert JSON string to Java object?

By Wayan Saryada in Jackson 2 Comments

In the following example we will convert JSON string to Java object using ObjectMapper class from the Jackson library. This class provides a method readValue(String, Class<T>) which will deserialize a JSON string into Java object. The first argument to the method is the JSON string and the second parameter is the result type of the conversion.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.databind.ObjectMapper;

import java.io.IOException;

public class JsonToObject {
    public static void main(String[] args) {
        String json = "{\"id\": 1, \"name\": \"The Beatles\"}";

        ObjectMapper mapper = new ObjectMapper();
        try {
            Artist artist = mapper.readValue(json, Artist.class);
            System.out.println("Artist = " + artist);

            System.out.println("artist.getId() = " + artist.getId());
            System.out.println("artist.getName() = " + artist.getName());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

The code snippet above will print to following output:

Artist = Artist{id=1, name='The Beatles'}
artist.getId() = 1
artist.getName() = The Beatles

How to convert Java object to JSON string?

By Wayan Saryada in Jackson 1 Comment

The following example shows how to convert Java object into JSON string using Jackson. Jackson provide ObjectMapper class provides functionality to read and write JSON data. The writeValueAsString(Object) method to serialize any Java object into string.

package org.kodejava.example.jackson;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

public class ObjectToJson {
    public static void main(String[] args) {
        Artist artist = new Artist();
        artist.setId(1L);
        artist.setName("The Beatles");

        ObjectMapper mapper = new ObjectMapper();
        try {
            String json = mapper.writeValueAsString(artist);
            System.out.println("JSON = " + json);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }
}

Running the code snippet above will print out the following result:

JSON = {"id":1,"name":"The Beatles"}

The structure of Artist class.

package org.kodejava.example.jackson;

public class Artist {
    private Long id;
    private String name;

    public Artist() {
    }

    public Artist(Long id, String name) {
        this.id = id;
        this.name = name;
    }

    // Getters & Setters

How do I do multipart upload using HttpClient?

By Wayan Saryada in Apache HttpComponents 1 Comment

This example demonstrates how to do multipart upload using the Apache HttpClient library. In this example we upload a single file. We start by creating an object of the file to be uploaded. The FileBody represent the binary body part of the file.

Next, prepare the HttpEntity object by create an instance of MultipartEntityBuilder. Add parts to this object, in this case we add the fileBody. We can add multiple part to this object as the name says. It can be string, file, etc as we do in a normal web form.

The build() method of the builder object finalize the entity creation and return us the HttpEntity object. To send / upload to server we create an HttpPost request and set the entity to be posted. Finally the execute() method of the HttpClient object send the multipart object to server.

package org.kodejava.example.httpclient;

import org.apache.http.HttpEntity;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.HttpClientBuilder;

import java.io.File;
import java.io.IOException;

public class HttpPostMultipartExample {
    public static void main(String[] args) {
        File file = new File("data.zip");
        FileBody fileBody = new FileBody(file, ContentType.DEFAULT_BINARY);

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        builder.addPart("file", fileBody);
        HttpEntity entity = builder.build();

        HttpPost request = new HttpPost("http://localhost:8080/upload");
        request.setEntity(entity);

        HttpClient client = HttpClientBuilder.create().build();
        try {
            client.execute(request);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

To receive the file on the server you can take a look at the servlet code in the following example: How do I create a web based file upload?.

How do I convert number into Roman Numerals?

By Wayan Saryada in Core API, Lang Package 0 Comment

You want to convert numbers into their Roman numerals representation and vice versa. The solution here is to tackle the problem as a unary problem where the Roman numerals represented as a single element, the “I” character. We start by representing the number as a repeated sequence of the “I” characters. And then replace the characters according to next bigger symbol in roman numeral.

To convert from the Roman numerals to numbers we reverse the process. By the end of the process we will get a sequence of repeated “I” characters. The length of the final string returned by this process is the result of the roman numerals conversion to number.

In the code snippet below we create two methods. The toRoman(int number) method for converting number to roman numerals and the toNumber(String roman) method for converting from roman numerals to number. Both of this method utilize the String.replace() method for calculating the conversion result.

Let’s see the code in action.

package org.kodejava.example.lang;

public class RomanNumber {
    public static void main(String[] args) {
        for (int n = 1; n <= 4999; n++) {
            String roman = RomanNumber.toRoman(n);
            int number = RomanNumber.toNumber(roman);

            System.out.println(number + " = " + roman);
        }
    }

    private static String toRoman(int number) {
        return String.valueOf(new char[number]).replace('\0', 'I')
                .replace("IIIII", "V")
                .replace("IIII", "IV")
                .replace("VV", "X")
                .replace("VIV", "IX")
                .replace("XXXXX", "L")
                .replace("XXXX", "XL")
                .replace("LL", "C")
                .replace("LXL", "XC")
                .replace("CCCCC", "D")
                .replace("CCCC", "CD")
                .replace("DD", "M")
                .replace("DCD", "CM");
    }

    private static Integer toNumber(String roman) {
        return roman.replace("CM", "DCD")
                .replace("M", "DD")
                .replace("CD", "CCCC")
                .replace("D", "CCCCC")
                .replace("XC", "LXL")
                .replace("C", "LL")
                .replace("XL", "XXXX")
                .replace("L", "XXXXX")
                .replace("IX", "VIV")
                .replace("X", "VV")
                .replace("IV", "IIII")
                .replace("V", "IIIII").length();
    }
}

The 10 randoms result of the conversion listed below:

18 = XVIII
208 = CCVIII
843 = DCCCXLIII
1995 = MCMXCV
2000 = MM
2017 = MMXVII
2562 = MMDLXII
3276 = MMMCCLXXVI
4067 = MMMMLXVII
4994 = MMMMCMXCIV

How do I send POST request with a JSON body using the HttpClient?

By Wayan Saryada in Apache HttpComponents 0 Comment

The following code snippet show you how to send POST request with a JSON body using HttpClient. The payload in this example is a user information containing id, first_name and a last_name. We placed the payload in an object called StringEntity and also set its content type to ContentType.APPLICATION_FORM_URLENCODED.

On the other end called by this post request, data can be read for instance in a Java Servlet using the HttpServletRequest.getParameter() method. For example to read the JSON body send below we can call request.getParameter("data"). Which will give us the payload send using the HttpClient Post request.

Let’s jump into the code snippet below:

package org.kodejava.example.httpclient;

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;

public class HttpPostJsonExample {
    public static void main(String[] args) throws Exception {
        String payload = "data={" +
                "\"username\": \"admin\", " +
                "\"first_name\": \"System\", " +
                "\"last_name\": \"Administrator\"" +
                "}";
        StringEntity entity = new StringEntity(payload,
                ContentType.APPLICATION_FORM_URLENCODED);

        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost request = new HttpPost("http://localhost:8080/register");
        request.setEntity(entity);

        HttpResponse response = httpClient.execute(request);
        System.out.println(response.getStatusLine().getStatusCode());
    }
}

How do I align string print out in left, right, center alignment?

By Wayan Saryada in Core API, Lang Package 0 Comment

The following code snippet will teach you how to align string in left, right or center alignment when you want to print out string to a console. We will print the string using the printf(String format, Object... args) method. The format specifier / parameter defines how the string will be formatted for output and the args is the value that will be formatted.

The format parameter / specifier include flags, width, precision and conversion-characters in the order shown below. The square brackets in the notation means the part is an optional parameter.

% [flags] [width] [.precision] conversion-character
Flags Description
- left-align the output, when not specified the default is to right-align
+ print (+) or (-) sign for numeric value
0 zero padded a numeric value
, comma grouping separator for number greater that 1000
space will output a (-) symbol for negative value and a space if positive
Conversion Description
s string, use capital S to uppercase the strings
c character, use capital C to uppercase the characters
d integer: byte, short, integer, long
f floating point number: float, double
n new line

Width: Defines the field width for printing out the value of argument. It also represents the minimum number of characters to
be printed out to the output.

Precision: For floating-point conversion the precision define the number of digits of precision in a floating point value. For string value this will extract the substring.

To center the string for output we use the StringUtils.center() method from the Apache Commons Lang library. This method will center-align the string str in a larger string of size using the default space character (‘ ‘). You can supply the third parameter to define your own space character / string.

package org.kodejava.example.lang;

import org.apache.commons.lang3.StringUtils;

import java.time.LocalDate;
import java.time.Month;
import java.time.temporal.ChronoUnit;

public class StringAlignment {
    private static Object[][] people = {
        {"Alice", LocalDate.of(2000, Month.JANUARY, 1)},
        {"Bob", LocalDate.of(1989, Month.DECEMBER, 15)},
        {"Carol", LocalDate.of(1992, Month.JULY, 24)},
        {"Ted", LocalDate.of(2006, Month.MARCH, 13)},
    };

    public static void main(String[] args) {
        String nameFormat = "| %1$-20s | ";
        String dateFormat = " %2$tb %2$td, %2$tY  | ";
        String ageFormat = " %3$3s |%n";
        String format = nameFormat.concat(dateFormat).concat(ageFormat);
        String line = new String(new char[48]).replace('\0', '-');

        System.out.println(line);
        System.out.printf("|%s|%s|%s|%n",
            StringUtils.center("Name", 22),
            StringUtils.center("Birth Date", 16),
            StringUtils.center("Age", 6));
        System.out.println(line);

        for (Object[] data : people) {
            System.out.printf(format,
                data[0], data[1],
                ChronoUnit.YEARS.between((LocalDate) data[1], LocalDate.now()));
        }

        System.out.println(line);
    }
}

Here is the output of our code snippet above:

------------------------------------------------
|         Name         |   Birth Date   | Age  |
------------------------------------------------
| Alice                |  Jan 01, 2000  |   17 |
| Bob                  |  Dec 15, 1989  |   27 |
| Carol                |  Jul 24, 1992  |   24 |
| Ted                  |  Mar 13, 2006  |   10 |
