How can I 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
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
