Can somebody help on what kind of questions can be expected in 1.4 exam on equals() and hashCode() methods? It would be gr8 help if somebody who has appeared for 1.4 exam and gone through attempting questions on these 2 methods can give a_close_to exam point of view answer!
You should know what constitutes a "legal" hash code. Basically, it's important to understand the general contract of hashcode. You can read that in the API Spec for Object (under the hashcode method).
As for equals, you should just be able to write one on your own. If you can do that, you're just fine.
I'd suggest reading this to get a good feel for hash codes.
