There are a few different ways to do this but this one will work just fine for your problem. (note these numbers are not truly random, but they will probably be random enough for your purposes) you will have to: import java.util.Random; then define a new random number generator called Generator: Random generator = new Random(); Then, make a random integer between 0 and 40 and subtract 20 so it is between -20 and positive 20. int myNumber = generator.nextInt(40) - 20;
I don't what you mean by good, but I have tested it and it creates a normal distribution also known as Gaussian.
Create a random number generator going between 1 - 6
A generator cord can be purchased at one's local hardware store, as well as local generator distributors. One can find generator cords on eBay and Amazon as well.
