The println(boolean) method of PrintStream Class in Java is used to print the specified boolean value on the stream and then break the line. This boolean value is taken as a parameter.

Syntax:

public void println(boolean booleanValue)

Parameters: This method accepts a mandatory parameter booleanValue which is the boolean value to be written on the stream.

Return Value: This method do not returns any value.

Below methods illustrates the working of println(boolean) method:

Program 1:

// Java program to demonstrate
// PrintStream println(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 println() method
            // This will put the booleanValue in the
            // stream till it is printed on the console
            stream.println(true);
  
            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}

Output:

true

Program 2:

// Java program to demonstrate
// PrintStream println(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 println() method
            // This will put the booleanValue in the
            // stream till it is printed on the console
            stream.println(false);
  
            stream.flush();
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
