here is how you use nextInt:

first create a random object

Random rand = new Random();

then call the nextInt method on that random Object

int myInt = rand.nextInt();

you can pass a parameter to the nextInt method to specify an exclusive range 

int myInt = rand.nextInt(20);

would produce a random number between 0 and 20 exclusively (so the highest number you could get would be 19)
