Я работаю с JPanel с именем infoPanel в предоставленном коде, что я хочу иметь возможность точно разместить JTextField с JLabel перед ним. Я попытался добавить JLabel к нему и не смог разместить там, где я хочу. Я хочу поставить его примерно на 20 пикселей ниже, чем в предоставленном коде, и перед ним я хочу добавить JTextField. Я также хотел бы сделать только JTextField.JTextField пошив одежды
Как я могу точно разместить JTextField и JLabels?
Какова наилучшая практика для этого?

ОК. Я сделаю некоторое исследование по этим вопросам, спасибо. – feltersnach
Кроме того, в вашем примере кода нет 'JLabel' ... – MadProgrammer
