import java.io.*;

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

        try {

            // Create a Writer instance
            Writer writer
                = new PrintWriter(System.out);

            // 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");

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

Output:

GeeksForGeeks

Program 2:

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

import java.io.*;

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

        try {

            // Create a Writer instance
            Writer writer
                = new PrintWriter(System.out);

            // 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:

GFG
