Below methods illustrates the working of append(CharSequence) method:
Program 1:
// 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 '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
