import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Print the value 'GFG'
// to this stream using print() method
// This will put the in the
// stream till it is printed on the console
stream.print("GFG");

catch (Exception e) {
System.out.println(e);
}
}
}
输出:
GFG
程序2。
// Java program to demonstrate
// PrintStream println() method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Print the value '1.65'
// to this stream using print() method
// This will put the in the
// stream till it is printed on the console
stream.print(1.65);
// Break the line in the stream
