check the equality of StringBuffers

[Vicken Karaoghlanian]

how can i test the equality of two different StringBuffers (s1, s2)??
Although s1.equals(s2) compiles fine, but it doesn't show the equality.
should i write a complete code to do that? isn't there any method i can use?
by the way should i know all the methods that are used to manipulate Strings and StringBuffer for the SCJP 1.4 exam?

StringBuffer class doesn't override equals() method, so you can't expect it to perform lexicographical comparison of the String contents as String would do. It helps to learn the most frequently used methods of String and StringBuffer and their behaviour for the exam.

You can use this:
s1.toString().equals(s2.toString())
