Can anybody explain why the equals() method in StringBuffer is not overriden?
Assuming in main() block:
StringBuffer s1=new StringBuffer("hello");
StringBuffer s2=new StringBuffer("hello");
The code returns false. I could not understand it? Help please.

Hi Jordan,
I've never come across any reason why <code>equals()</code> isn't overridden in <code>StringBuffer</code>; just that it isn't.
Not much help, I know ... you just need to remember that <code>String</code> and the Wrapper classes overload <code>equals()</code> and that <code>StringBuffer</code> doesn't.
