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
