String in Java are immutable, ihat is once a String is initialized with  certain value it cannot be changed but the reference to that String can be change to another String. While a String Buffer size can be always altered. The contentsof the StringBuffer can be changed by appending ned string or concatinating them with the later Strings.

Generally there will be asmall java code written in the interview where you will find that a String will be in a Loop and some constand String will be getting Added to the existing String. The wnswer will befinetly be the aaaaaaaaaaaaaaaaaaaaaaaa, if "a" is appended  soem nnuber of time, here Java will internally create a internal StringBuffer and do it for U.

           String class is used to manipulate character strings that cannot be changed. Simply stated, objects of type String are read only and immutable. The StringBuffer class is used to represent characters that can be modified.

         The significant performance difference between these two classes is that StringBuffer is faster than String when performing simple concatenations. In String manipulation code, character strings are routinely concatenated.
