Ummm... isn't the substring() method enough by itself?

To remove first two chars:

To remove last two chars:

Of course for robust code you prbably want to make sure that there really are at least two chars in the string, before you remove them.

This works well would you say its overdoing it? Do I need to use the string buffer? Is s = s.substring(2); using StringBuffer under the hood?

And of course you're not removing anything from the String. You're creating a new String that's the old String minus the stuff you want removed.

Perhaps this is overdoing it if you only want to remove the first 2 chars (or the last 2). However, if you want to remove chars from the middle of a String, this is probably better than trying to use substring().
