Random Class nextBoolean() method

• nextBoolean() method is available in java.util package.
• nextBoolean() method is used to return the next pseudo-random Boolean value from this Random Value Generator.
• nextBoolean() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• nextBoolean() method does not throw an exception at the time of returning boolean.

Syntax:

    public boolean nextBoolean();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is boolean, it returns the next pseudo-random distributed boolean value.

Example:

// Java program to demonstrate the example 
// of boolean nextBoolean() method of 
// Random

import java.util.*;

public class NextBooleanOfRandom {
 public static void main(String args[]) {
  // Instantiates Random object
  Random ran = new Random();

  // By using nextBoolean() method is
  // to return the next to next
  // pseudo-random boolean value from
  // this Random Value Generator
  boolean val = ran.nextBoolean();

  // Display val
  System.out.println("ran.nextBoolean(): " + val);
 }
}

Output

RUN 1:
ran.nextBoolean(): false

RUN 2:
ran.nextBoolean(): true

RUN 3:
ran.nextBoolean(): false
