    import java.util.Random;

    Random randGen = new Random();

    What you do next depends on the type of random numbers you wish to generate; two possibilities are:

    int myInt;
    myInt = randGen.nextInt();

    float myFloat;
    myFloat = randGen.nextFloat();

    ----------------------------------------------------

    String myString = "Hi punjabian263!";

    String myUpString = myString.toUpperCase();

    a fast and dirty approach:

    Math.random() generates a number between 0.000 and 1.000

    so for a random number between 0 and 1000:

    int randomInt = Math.random() * 1000
