public static void main(String[] args) {
  NumberFormat format = NumberFormat.getInstance();
  NumberFormatter formatter = new NumberFormatter(format);
  formatter.setValueClass(Integer.class);
  formatter.setMinimum(0);
  formatter.setMaximum(Integer.MAX_VALUE);
  formatter.setAllowsInvalid(false);
  // If you want the value to be committed on each keystroke instead of focus lost
  formatter.setCommitsOnValidEdit(true);
  JFormattedTextField field = new JFormattedTextField(formatter);

  JOptionPane.showMessageDialog(null, field);

  // getValue() always returns something valid
  System.out.println(field.getValue());
}
