Unsigned shift operation yields different results for same number of shift

Question

Why does it yield two different results if in both cases we are performing 32 bits unsigned right shift?

public class Main {
    public static void main(String[] args) {
        int i = -1;
        i = i>>>31;
        i = i>>>1;
        
        int j = -1;
        j = j>>>32;
        
        System.out.println(i);
        System.out.println(j);
    }
}

Output is:

0
-1
