Parameters: This method accepts a mandatory parameter charSequence which is the CharSequence to be written in the writer.

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:

Program 2:




// Java program to demonstrate
// StringWriter append(CharSequence) method
  
import java.io.*;
  
class GFG {

        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");
