Implementing the equals method in java

Question

This is my implementation of the equals class for a Coor class which is just contains 2 ints x and y. would this be the proper way of implementing this method?

Answer 1

Yes, it would.

Also be sure to override your hashCode() method--never override one without doing the other as well, it will confuse the hell out of your collections.

Your case could use a hash where it simply shifts one of the ints 32 bits and adds it to the other creating a completely unique long (a perfect hash function in this case--no collisions)
