How do I read file contents to string using Commons IO?

In this example we use FileUtils class from Apache Commons IO to read the content of a file. FileUtils have two static methods called readFileToString(File) and readFileToString(File, String) that we can use.

An example to read file contents and return the result as a string can be seen below.




public class ReadFileToStringSample {
    public static void main(String[] args) {
        // Here we create an instance of File for sample.txt file.
        File file = new File("sample.txt");

        try {
            // Read the entire contents of sample.txt
            String content = FileUtils.readFileToString(file, "UTF-8");
            System.out.println("File content: " + content);
        } catch (IOException e) {
