Returns the next pseudorandom, uniformly distributed int value from the Math.random() sequence.

Usage

From source file:MainClass.java

public static void main(String[] args) {
    //Random Value Generation
    System.out.println("Random double >>> " + RandomUtils.nextDouble());
    System.out.println("Random float >>> " + RandomUtils.nextFloat());
    System.out.println("Random int >>> " + RandomUtils.nextInt());
}

From source file:MathUtilsTrial.java

public static void main(String[] args) {

    // Random Value Generation
    System.out.println("Random double >>> " + RandomUtils.nextDouble());
    System.out.println("Random float >>> " + RandomUtils.nextFloat());
    System.out.println("Random int >>> " + RandomUtils.nextInt());

}
