Los siguientes programas ilustran el funcionamiento del método append(CharSequence):
Programa 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);
}
}
}
