Long l=new Long("127");
l.toString()==l.toString()//gives false.

When ever toString() method is called on a object a new string object is created or i m missing some thing.

l.toString()==l.toString() creates two new strings where in case the == returns false.

If == returns false when comparing two objects then they are different objects. So the answer is yes; Long.toString() returns a new unique String instance each time its called.
