String are once created, we can't modify it. Any such attempt will create a new string. In Stringbuffer one can can the insert,delete,append character after it is created. String values are resolved at compile time. So if we know the exact size of the string to be appended, better use String object. In StringBuffer values resolved at runtime, one can appened any number of String.only one StringBuffer is used to hold. No new object will be created. which is very fast
