You can use Math.random() to generate random number between 0.0 to 1.0, later you can multiply it to 10 or 100 depending upon how many random number you will need, mostly depends upon how many elements you have in your array. Since here you three elements, you just multiply with 3 and cast it to int. For code example, you can take a look here
