Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence.

Usage

From source file:Main.java

public static void main(String[] argv) {

    Random r = new Random();
    int randint = Math.abs(r.nextInt()) % 11;
    System.out.println(randint);/*from  www  .  j  a v a 2 s . com*/
}

From source file:Main.java

public static void main(String args[]) {
    anArray = new double[10];
    Random rand = new Random();
    for (int i = 0; i < 10; i++) {
        anArray[i] = rand.nextInt();
    }//from w  ww.  java2  s. c  om
    System.out.println(Arrays.toString(anArray));
}

From source file:Main.java

public static void main(String args[]) {

    Random randomno = new Random();

    // get next next pseudorandom value 
    int value = randomno.nextInt();

    // check the value  
    System.out.println("Value is: " + value);
}

From source file:Main.java
