The code snippet below is an example of how to read a text file. This program will read a file called test.txt and shows its content.

package org.kodejava.example.io;

import java.io.*;

public class ReadTextFileExample {
    public static void main(String[] args) {
        File file = new File("/Users/wsaryada/kodejava/test.txt");

        try (BufferedReader reader =
                     new BufferedReader(new FileReader(file))) {
            StringBuilder contents = new StringBuilder();

            String text = null;
            while ((text = reader.readLine()) != null) {
                contents.append(text).append(
                        System.getProperty("line.separator"));
            }

            System.out.println(contents.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
