All ,

My understanding is that HashMap can not contain keys .
How come the size of the Map in the following code is 5 instead of 3?
I thought ob4 and ob3 are duplicates and they can not be inserted as keys.

Please provide What i am missing ? . here is the code

Note that you didnt override hashCode() correctly, watch case. If modified then size should be 3.

When you override a method, make sure you get the case and signature correct. In this case, the hashCode() method has a capital C.

In the future, to prevent making this mistake, declare overriden methods with the @Override annotation, it will report an error if you are not actually overriding.
