Question

I want to know if it possible to write this method in one line. I need to compare y-coordinates and break ties using the x-coordinates.

 // comparing y-coordinates and breaking ties by x-coordinates
    public int compareTo(Point p) {

        if (y < p.y) {
          return -1;
        }
        if (y > p.y) {
           return 1;
        }
        if (x < p.x) {
          return -1;
        }
        if (x > p.x) {
         return 1;
        }
       return 0;
    }

Answer 1

This should work (but I wouldn’t recommend it for readability):

return y < p.y ? -1 : y > p.y ? 1 : x < p.x ? -1 : x > p.x ? 1 : 0;

I haven’t bothered to check, but I would guess that the compiler generates exactly the same byte codes as for your original code.
