How do I get the output to produce random numbers?

This is what I have so far

    import java.util.Arrays;

public class Randoms {

    public static void main(String[] args) {
        int[] array = new int [50];
        for (int index = 0; index < array.length; index++) {
            int j = (int) Math.random() * 101 + 1;

            System.out.println(j);
        }

    }

}

My output just produces a bunch of 1s. I want numbers from 0-100? Any help would be appreciated. I am fairly new to Java so sorry if this is a really dumb mistake. Thanks in advance.
