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

import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter printr
= new PrintWriter(System.out);
// Print the boolean value 'false'
// to this stream using print() method
// This will put the booleanValue in the
