用示例在 Java 中打印流打印(布尔)方法

原文:https://www . geesforgeks . org/print stream-print boolean-in-Java-method-with-examples/

Java 中 【打印流】 类的打印(布尔)方法用于在流上打印指定的布尔值。这个布尔值被作为一个参数。

语法:

public void print(boolean booleanValue)

参数:该方法接受一个强制参数布尔值，它是要写入流中的布尔值。

返回值:此方法不返回值。

下面的方法说明了打印(布尔)方法的工作原理:

程序 1:

// Java program to demonstrate
// PrintStream print(boolean) 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 boolean value 'true'
            // to this stream using print() method
            // This will put the booleanValue in the
            // stream till it is printed on the console
            stream.print(true);

            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

true

程序 2:

// Java program to demonstrate
// PrintStream print(boolean) 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 boolean value 'false'
            // to this stream using print() method
            // This will put the booleanValue in the
            // stream till it is printed on the console
            stream.print(false);

            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

false
