Returns a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive), drawn 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 = r.nextInt(10);
    System.out.println(randint);/*from   w  w  w. j ava 2 s .  co  m*/
}

From source file:MainClass.java

public static void main(String[] args) {
    Random diceValues = new Random();
    System.out.println(diceValues.nextInt(6));
    System.out.println(diceValues.nextInt(6));
}

From source file:Main.java

public static void main(String[] args) {

    String[] arr = { "A", "B", "C", "D" };
    Random random = new Random();

    int select = random.nextInt(arr.length);

    System.out.println("Random String selected: " + arr[select]);
}

From source file:Main.java

public static void main(String[] argv) throws Exception {

    Random rand = new Random();

    int n = 10;/*from ww w .j  ava  2  s  .com*/
    int i = rand.nextInt(n + 1);
    System.out.println(i);
}

From source file:Test.java

    myLock.lock();//from w ww  . ja v  a2  s. co  m
    int number = random.nextInt(5);
    int result = 100 / number;
    System.out.println("A result is " + result);
    FileOutputStream file = new FileOutputStream("file.out");
    file.write(result);
    file.close();
}

From source file:Main.java

    }//from   w  w w.j  a  v a  2 s .  c  o m
    System.out.println(intSet);
}

From source file:Main.java

        System.out.println(randomNum);
    }/*w  w  w. j  a  v  a 2s .  c  o m*/
}

From source file:Main.java

public static void main(String[] args) {

    }//from   ww w  .j a v  a  2s  . co  m
    Date before = new Date();
    Arrays.sort(anArray);
    Date after = new Date();
    System.out.println("milli seconds" + (after.getTime() - before.getTime()));
}

From source file:Main.java

public static void main(String args[]) {

    Random randomno = new Random();

    // check next int value  
    System.out.println("Next int value: " + randomno.nextInt(10000));
