add key listener in textfield... use keyReleased and use the code below

char k_code = evt.getKeyChar();

if((Character.isDigit(k_code)) || (k_code==evt.VK_PERIOD))

text.setText(text.getText());

else

text.setText(text.getText().substring(0,text.getText().length()-1));

Hi,

I've implemented number fields based on JFormattedTextField.

They also support a min and a max value.

Maybe you find them useful (the library is open source):

Puce is also right... I think you should use JFormattedTextFieldI always use JFormattedTextField when it comes to formatting inputs..
