Do you mean 'pool' memory, as in the String pool ?

In java , When ever you creates string litelars , they will be created in String pool ( pool memory).

s="abc"; creates one object in pool memory
and String s=new String("abc"); creates two objects. I hope one in pool and other one in non pool .

Pls correct me if am wrong.
