Return Value: This method returns this StringWriter instance.

Below programs illustrates the working of append(CharSequence) method:

Program 1:

// Java program to demonstrate
// StringWriter append(CharSequence) method

import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        try {

            // Create a StringWriter instance
            StringWriter writer
                = new StringWriter();

            // Write the CharSequence 'GeeksForGeeks'
            // to this writer using append() method
            // This will put the charSequence in the writer
            // till it is printed on the console
            writer.append("GeeksForGeeks");

            System.out.println(writer.toString());
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

GeeksForGeeks

Program 2:

// Java program to demonstrate
// StringWriter append(CharSequence) method

import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        try {

            // Create a StringWriter instance
            StringWriter writer
                = new StringWriter();

            // Write the CharSequence 'GFG'
            // to this writer using append() method
            // This will put the charSequence in the writer
            // till it is printed on the console
            writer.append("GFG");

            writer.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:
