HasMap iteration

I have a map returned from a function.

Now I wish to get the keys and values from this map..

But i dont have any idea about both the keys as well as values...

I can iterate about the map and get all the values using .get(key);

but how shall i get the keys in the first place..

HashMap provides keySet(), values(), and entrySet() that can all be iterated. The last one holds Map.Entry objects with getKey(), getValue(), and setValue().
