| - | Μέχρι τώρα είδαμε πως μπορείτε να προσθέσετε ένα κουμπί σε ένα JFrame. Εάν θέλετε να προσθέσετε κάποιο κείμενο σε ένα JFrame θα χρειαστείτε ένα label (JLabel) για να το κάνετε όπως παρακάτω: | ||
| - | |||
| - | <code java LabelGreeting.java> | ||
| - | import javax.swing.*; | ||
| - | import java.awt.event.ActionListener; | ||
| - | import java.awt.event.ActionEvent; | ||
| - | |||
| - | public class LabelGreeting extends JFrame { | ||
| - | public LabelGreeting () { | ||
| - | super(); | ||
| - | setSize(200, | ||
| - | setTitle(" | ||
| - | JLabel greeting = new JLabel(" | ||
| - | add(greeting); | ||
| - | } | ||
| - | | ||
| - | public static void main(String[] args) { | ||
| - | LabelGreeting lg = new LabelGreeting(); | ||
| - | lg.setVisible(true); | ||
| - | } | ||
| - | } | ||
| - | </ | ||
