Stringisimmutable, if you try to alter their values, another object gets created, whereasStringBufferandStringBuilderaremutableso they can change their values. Thread-Safety Difference: The difference betweenStringBufferandStringBuilderis thatStringBufferis thread-safe. So when the application needs to b...
StringBuffer is A thread-safe, mutable sequence of characters. A string buffer is like a String, but can be modified. At any point in time it contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls. String buffe...
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...
