How to include negative numbers in random number generation?

Hello,I have been trying to create 100 random integers that has just -1, 0 and 1. But since this range has a negative number, I'm confused as what method to use. Any help would be greatly appreciated.Thanks.

Using java.util.Random can you just generate 0, 1 and 2? Then what can youdo to 0, 1 and 2 to transform them to -1, 0 and 1?

public class Randoms {

public static void main(String[] args) {

Random rand = new Random(System.currentTimeMillis());

for(int i = 0; i < 100; i++) {

int r = rand.nextInt(2) -1;

System.err.println(r);

}

Get a (pseudo) random number between 0 and 2, subtract 1 of that generated number.
