We all know String literals are allocated memory in Pool Interns.My doubt is how Java deallocates the memory after the usage of String literal.

I am guessing the lost literals would be garbage collected when the JVM feels like

As Fred said, it doesn't get garbage collected...

I don't see your point. String literals are a special case. They are handled a little different than other objects, so they are not eligible for GC.

There may be some strange, esoteric case where is it possible, but none that I am aware of.

How strings objects are cleaned..or GC'ed in some or the other way is not part of the exam.
