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);        }    }} |
Output:
false
