import java.lang.*;
public class StringBufferDemo {
   public static void main(String[] args) {
      StringBuffer buff = new StringBuffer("tutorials point");
      System.out.println("buffer = " + buff);
      // reverse characters of the buffer and prints it
      System.out.println("reverse = " + buff.reverse());
      // reverse of the buffer is equivalent to the actual buffer
      buff = new StringBuffer("malyalam");
      System.out.println("buffer = " + buff);
      // reverse characters of the buffer and prints it
      System.out.println("reverse = " + buff.reverse());
   }
}

buffer = tutorials point
reverse = tniop slairotut
buffer = malayalam
reverse = malayalam
