it returns a set.
so does it contain both the 'key' and 'value' in case of hashmap??

If you take a look at the API documentation for the Map.entrySet() method it should be pretty obvious what exactly is returned.

Yuvraj,
Yes. The JavaDoc for Java 5+ shows this a bit more clearly. It says the return type is:
Set<Map.Entry<K,V>>
This is a Set of Entry objects. The Entry class is defined within Map and has the key/value pairs.
