Yes I understand that. In fact, as I pointed out in a subsequent post, none of my code defines equals, Node was however extending AbstractSet which does redefine it. Really All I was looking for was a general direction I might look and not to burden anyone with large blocks of code. Node is 212 lines, Gate is 67, Monitor another 85, none of which even once mentions the word "equals"  

My issue with Roedy's response was not the helpful suggestion to look at super classes but rather that it comes off as lecturing, and frankly rather condescending.
