my question:
when we declare the string literal, its created in the string constant pool in the heap. But when we are invoking the new to create a string with same value,is it creating a new String object in the heap or the reference variable is simply pointing the literal in the string constant pool??

When you use new operator, a new String object will be created in the heap...

Don't worry about the free memory. If you want to check if a new object is created, just compare the two String objects using equality operator (==)...

yes you are right.. the equality operator checks if the reference variables are pointing at the same object or not
thanks
