Just want to make sure whether the StringBuffer class overrides the equals() method of the Object class.
I say no. It doesn't override it.
So,
StringBuffer sb1 = new StringBuffer("Amit");
StringBuffer sb2= new StringBuffer("Amit");
sb1.equals(sb2) returns false.

Val is right. You really should consult the documentation for questions like this. It'll help you in the long run, if you familiarize yourself with the apis.

StringBuffer class doesnot override equals(). That is when we use equals() for StringBuffers, what is done is just reference comparasion - the behaviour inherited from Object class. Boolean and String classes override equals() method. Thus when two strings are compared - comparison is done for equality of string contents not thier handles.
