Hi All,

I have seen HashMap has extended AbstractHashMap that implements Map interface. But HashMap has also implemented Map. What is the reason behind that?

I guess no reason. Maybe for clarity. Anyway it doesn't really matter, it's not like you can double implement an interface.

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.
