1.はActionListenerで適当な文字列をsetLabelすればいい
import java.awt.*;
import java.awt.event.*;
public class Res170 {
public static void main(String[] args) {
Button b = new Button("開始");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Button b = (Button)e.getSource();
b.setLabel(b.getLabel().equals("開始") ? "停止" : "開始");
}
});
Frame f = new Frame();
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
((Frame)e.getSource()).dispose();
}
});
f.add(b);
f.pack();
f.setVisible(true);
}
}
