eg: NAME den take in N only....help me?...lol..Assuming you already know how to get input using the Scanner class, just chain the charAt() method after calling the next() method.

More information about the charAt() method here.
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#charAt(int)
Basically, what you are doing here is, when you call the next() method, it returns a String object which contains the input from the user (it's actually a token of the user input but we won't talk about it here). The charAt() method, coming from the String class, allows you to pick a character out of a String object. Say, for example, a user types in "sgForums" as input. If I want to retrieve the 3rd letter 'F', the offset of the letter would be 2 (skip 2 letters), thus I would call next().charAt(2) from a Scanner object.
If you don't understand any part of my post, please don't hesitate to clarify with me.
