Answer / payal gupta

It is an advantage that a String class is immutable because
almost all the standard classes use its methods, if they
were mutable, then the behaviour of other standard classes
and their methods would not have been consistent.

Answer / ashish balhara

The performance for String is poor as compared to String
Buffer, as internally (for eg. a simple operation like + on
String), it generates String Buffer, calls append operation
(eqvt. of + in String) & converts result back to String.
Hence extra bytecode is generated which could be done away
with.
