StringBuffer is thread-safe and synchronized whereas StringBuilder is not. That’s why StringBuilder is faster than StringBuffer. String concatenation operator (+) internally uses StringBuffer or StringBuilder class. For String manipulations in a non-multi threaded environment, we should use StringBuilder...
