Description:

This is one of the most popular interview question on String in Java which starts with discussion of What is immutable object , what are the benefits of immutable object , why do you use it and which scenarios do you use it.

It can also come once interviewee answers some preliminarily strings questions e.g. What is String pool , What is the difference between String and StringBuffer , What is the difference between StringBuffer and StringBuilder etc.

Though there could be many possible answer for this question and only designer of String class can answer this , I think below two does make sense
