{

try {

import java.io.*;

class GFG {

public static void main(String[] args)

{

try {

// Create a PrintWriter instance

PrintWriter printr

= new PrintWriter(System.out);

// Print the int value '65'

// to this stream using print() method

// This will put the intValue in the

// stream till it is printed on the console

printr.print(65);

printr.flush();

}
