import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter writer
= new PrintWriter(System.out);
// Get the String
// to be printed in the stream
String string = "GeeksForGeeks";
// print the string
// to this writer using print() method
// This will put the string in the stream

GeeksForGeeks
示例2:
// Java program to demonstrate

PrintWriter writer
= new PrintWriter(System.out);
// Get the String
// to be printed in the stream
String string = "GFG";
// print the string
// to this writer using print() method
// This will put the string in the stream
