Comparator with double type

Question

I have written the following code:

public class NewClass2 implements Comparator
{
    public int compare(Point p1, Point p2)
    {
        retur         


        

Answer 1

You don't need to return double.

The Comparator interface is used to establish an ordering for the elements being compared. Having fields that use double is irrelevant to this ordering.

Your code is fine.

Sorry, I was wrong, reading the question again, this is what you need:

public class NewClass2 implements Comparator {
    public int compare(Point p1, Point p2) {
        if (p1.getY() < p2.getY()) return -1;
        if (p1.getY() > p2.getY()) return 1;
        return 0;
    }    
}
