Need custom JTextField for currency

Question

I have people entering alot of ammounts in form, so pressing one key less is what will count on huge ammounts of data.

Idea is not to press decimal separator when entering currency ammount. I need some subclass of JTextField which will automatically show decimal and thousand separators while entering number. Is out there something already developed for instant use? Found nothing on google..

thx

Answer 1

You can use a JFormattedTextField http://java.sun.com/docs/books/tutorial/uiswing/components/formattedtextfield.html,

Answer 2

You can set an InputVerifier that can enforce any rules you want. This example shows a simple currency format and a data/time verifier that accepts multiple formats. You can adapt it to accept the default format and interpret a missing decimal separator as a value in cents.
