Hi,
First you need to rectify the question. Because StringBuffers append the data, and Strings concatenate the data. Since Strings are immutable a new object is created for each concat operation. So it is better to use StringBuffer when you are append different data to the same StringBuffer object.

The main benefit of String is immutability which differentiate it from Stringbuffer but in case of string manipulation this advantage becomes biggest disadvantage and creates lots of garbage also using "+" operator for String concatenation is very slow as compared to StringBuffer.append()method which cost you some performance.
