String is immutable where as StringBuffer is mutable. The significant performance difference between these two classes is that StringBuffer is faster than the String when performing simple concatenations.

More specifically, StringBuffer is faster for concatenations that cannot be done in a single expression, i.e. when it's done in a loop.
