package com.tutorialspoint;

import java.lang.*;

public class StringBufferDemo {

   public static void main(String[] args) {

      StringBuffer buff = new StringBuffer("tuts ");
      System.out.println("buffer = " + buff);

      // appends the boolean argument as string to the string buffer
      buff.append(true);
      
      // print the string buffer after appending
      System.out.println("After append = " + buff);

      buff = new StringBuffer("abcd ");
      System.out.println("buffer = " + buff);
      
      // appends the boolean argument as string to the string buffer    
      buff.append(false);
      
      // print the string buffer after appending
      System.out.println("After append = " + buff);
   }
}

Let us compile and run the above program, this will produce the following result −

buffer = tuts
After append = tuts true
buffer = abcd
After append = abcd false
