free the space after remove from hashmap

[Shikha]

Hello,
I wish to remove a key value pair from hashmap. if i use remove() it
removes the key-value but still keeps the space and assigns a null
there. i want it to free that space. is there a method to do this ?

I'm not sure what the problem is. If I use remove() on a hashmap it
removes the key and the value and I can not see any 'null' values in
the map.

Could you provide a code example and some more pointers to where you
can see the 'null' value?

incorrect way....
