Generate Random Booleans in Java

To generate random booleans like TRUE or FALSE, at first create a new Random object −

Random randNum = new Random();

Now, loop through the count of booleans you want and generate random booleans with nextBooleans() method −

for (int i = 1; i <= 5; ++i) {
   booleanrandomRes = randNum.nextBoolean();
   System.out.println(randomRes);
}

Example

 Live Demo

import java.util.Random;
public class Demo {
   public static final void main(String... args) {
      Random randNum = new Random();
      System.out.println("Displaying random Booleans...");
      for (int i = 1; i <= 5; ++i) {
         boolean randomRes = randNum.nextBoolean();
         System.out.println(randomRes);
      }
   }
}

Output

Displaying random Booleans...
true
false
false
true
true

Let us run it again to get distinct random boolean −

Displaying random Booleans...
false
false
true
true
false
