if x.equals(y) is true, then x.hashCode() == y.hashCode()must be true.
If the above statement is true, why is that contract of equals method does not mention this requirement?
Thanks

Hi Barkat,
It does not get mentioned in equals() contract becuase it belongs to hashCode() contract.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
