what is the difference between stringbuffer and stringbuilder class in java?

StringBuffer: It is a class in java whose object represents the mutable string. It is just like string class except that its object can be modified. StringBuffer is synchronized, hence it is thread-safe.

StringBuilder: It is same as StringBuffer except that StringBuilder is not synchronized, hence it is not thread-safe.

StringBuffer is synchronized whereas StringBuilder is not synchronized.
