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
