Is there any way to accept only numeric values in a JTextField?

Question

Is there any way to accept only numeric values in a JTextField? Is there any special method for this?

Answer 1

Try this out in the key pressed event for the related JTextField.

private void JTextField(java.awt.event.KeyEvent evt) {

    // TODO add your handling code here:
    char enter = evt.getKeyChar();
    if(!(Character.isDigit(enter))){
        evt.consume();
    }
}
