Java AppendableWriter-class And Method Code Example

I apologize, but the Apache Commons IO library does not have a class called AppendableWriter either. But it has FileUtils class that has a method appendFile which can be used to add contents to the end of a file.

Here is an example of how to use the FileUtils class from the Apache Commons IO library in Java to append text to a file:


public class AppendFileExample {

    public static void main(String[] args) {
        // Define the file to be appended
        File file = new File("example.txt");

        // Define the text to be appended
        String text = "This is the text that will be appended.";

        try {
            // Append the text to the file
            FileUtils.writeStringToFile(file, text, true);
            System.out.println("Text appended to file.");
        } catch (IOException e) {

This example will append the text "This is the text that will be appended." to the end of the file "example.txt". The third parameter of the writeStringToFile method is set to true so it will append the text to the file.
