TTEXTFIELD in java

How to create ttextfield in java?

What's a "ttextfield"? I googled the term and found a few obscure references, but nothing which looked relevant to "in java".

I've also found it very difficult to get the meaning of "ttextfield" and what i found out is that it is just like a simple "textfield" but consist of some rules or obligations, such as it will accept only numbers(or only letters) from keyboard, or it can make the small letters entered by users into capital letters...
This is all what i've got...so anyone please help me..

If you don't know what it is, then it's pretty hard to tell you how to implement it.

Perhaps you can ask the person who told you to make one of those things what they are and why they made up that name?

Anyway as a general rule to make a JTextField which restricts what can be typed into it, you can use a Formatted Text Field or a Document Listener or Filter.
