How to compare stringbuffers in java??

Question

..

Answer 1

All methods in StringBuffer class are synchronised. StringBuffer came in java 1.0 version. StringBuffer class is thread safe. Performance wise we can't use this class because only one task is execute at a time. And we can change the existing object in StringBuffer class. this changeable behaviour is known as mutable..

Answer 2

I think
if (Nameofstringbuffer.equals ());
can be used
i m not 100 %sure
