import java.lang.*;

public class StringBufferDemo {
 
  public static void main(String[] args) {
  
    StringBuffer buff = new StringBuffer("India ");
    System.out.println("buffer = " + buff);

    // append character to the stringbuffer
    buff.append('!');
    // convert to string object and print it
    System.out.println("After append = " + buff.toString());
      
    buff = new StringBuffer("Hi "); 
    System.out.println("buffer = " + buff);
    // append integer to the stringbuffer
    buff.append(123);
    // convert to string object and print it
    System.out.println("After append = " + buff.toString());
