What is the basic difference between string and stringbuffer object?

Hi,
Here is the answer.
String is a class that represents an immutable string, that is a sequence of characters that can never change. Any modification to the String will have to create a new String object. A StringBuffer (and in Java 1.5 and up, a StringBuilder) is a mutable string object that can be modified at runtime.
The advantages of using Strings are that the String is generally lighter and faster to use where the String isn't going to change. When building a long String of text by making changes to one object over time, you should use a StringBuilder or StringBuffer (in Java 1.4 or when synchronization is important).
Thanks.
