Hi
We have two classes namely String and StringBuffer.
If we can do everything with StringBuffer, then what is the
need for String class.

They are for different purposes. A StringBuffer is used when you want to insert/remove/splice/etc characters on the fly, something Strings can't do. A StringBuffer might be loosely thought of as an ArrayList of chars, since it can grow and shrink dynamically. A String can not change its size.
HTH!

The String class is there for speed/performance. It does not carry the same overhead as a StringBuffer object.
