HI all, I came across this question in Whizlabs software.
StringBuffer s = new StringBuffer("abcd");
invoking length() of String class didnt give any errors i.e. s.length();
Does anybody know the reason. I thought that it cannot use the methods of String class.
Thanks in Advance,
Latha

s is a StringBuffer and StringBuffer has a length() method.
Where do you see String.length() being called in your example?

I am not sure what exactly your problem is. There is a length() method for StringBuffer and s here is a StringBuffer.
