Is there a way to limit the numeric value of JTextField

Question

I am using the KeyEvent for the user to key in only numbers

private void txtvalue1KeyTyped(java.awt.event.KeyEvent evt) {                                 
    char c = evt.getKeyChar();
    if(!(Character.isDigit(c))|| c==KeyEvent.VK_BACK_SPACE ||  c==KeyEvent.VK_DELETE){
        evt.consume();
    }
}

My question is, is there a way to limit the max/min value in the text to # number. For example I want to limit the value of my textfield min of "1" and max value of "12".

Don't use a KeyListener. For example your code won't work if text is pasted into the text field. Swing has newer and better API's as suggested below. — camickr, Oct 09 '15 at 05:56

Use a JSpinner. See the section from the Swing tutorial on How to Use Spinners for working examples.

A spinner will do the editing for numeric values and a valid range.

Or `JFormattedTextField` or `DocumentFilter` – MadProgrammer Oct 09 '15 at 05:49
