Я уже давно учусь программировать java. Я слышал, если у меня есть какие-либо проблемы с моим кодом, я могу спросить здесь, поэтому я делаю это сейчас, я думаю. Сейчас я учусь использовать аддон Windowbuilder в Eclipse. Я слышал, что добавление слушателя действий решит мою проблему, но есть другая проблема. Я не знаю, возможно ли добавить слушателя действия и связать все с ним после того, как все спроектировано. Я хочу слушать эти поля, потому что мне нужны предопределенные переменные для расчета. Мне нужно прослушать getEggAmount, getMilkAmount и getFlourAmount JTextFields. Мой класс mainmenu здесь:
public class main {
private JFrame frmBlinmaker;
private JTextField getMilkAmount;
private JTextField getFlourAmount;
private JLabel MilkAmount;
private JLabel FlourAmount;

private JLabel setMakeableBlins;

makeable k = new makeable();
