How to write a TableModelListener[^]

You might want to read that. There are multiple Listener-Implementations, choose the one that seems to be the right one for you. I can recommend the TableModelListener - but also the FocusListener[^] (focusLost(FocusEvent e) ) might suite your needs.

No matter which one you might choose, you need to validate the entered String. You can parse the entered String and react on the NumberFormatException and set up a switch-condition to limit the range.

I want when user input characters, this value will not display on editor of table, it is same with command return true or false of event KeyPress in DOT NET.

please make a little search on "validate int java" and see the link above for a Listener-implementation. it's no secret, you can read it all in the WWW.

I can also recommend o buy a book, it's got the advantage that you do not need to know any "search engine keywords" to read it.
