Я работаю над проектом по управлению сотрудниками с помощью SQL Server и Java. При добавлении функционала для addEmployee я столкнулся с этой проблемой.
Я не могу ссылаться на компоненты JTextField (txtName, txtAge и txtAddress). Я могу что-то упустить. При попытке создать метод jButtonActionPerformed() для кнопки Add, getText() для всех текстовых полей выдает ошибку, и ни одно из имен текстовых полей не отображается для автокоррекции, как если бы они не существовали.
Может кто-нибудь помочь мне понять, как использовать объекты текстового поля в этом коде?
