Unexpected output using comparator

Question

I have the following program

import java.util.*;
public class Test {
    public static void main(String[] args) {
        Integer[] array = { 3, 1, 4, 1, 5, 9 };
        Arrays.sort(array, new Comparator<Integer>() {
            public int compare(Integer i1, Integer i2) {
                return i1 < i2 ? -1 : (i2 > i1 ? 1 : 0);
            }
        });
        System.out.println(Arrays.toString(array));
    }
}

This gives me the output [3, 1, 4, 1, 5, 9]. Why?

Answer 1

because i1 < i2 is the same as i2 > i1 - look what you've written in your compareTo method.
