swing學習第四天，comboBox 下取得選擇變換的值

public class Test1 extends JApplet implements ActionListener  {
    private JCheckBox checkBox = new JCheckBox("Editable");

    contentPane.setLayout(new FlowLayout());
    contentPane.add(checkBox);
    contentPane.add(comboBox);
    checkBox.addActionListener(this);
    //comboBox.addActionListener(this);
    comboBox.addItemListener(new ItemListener() {

        public void itemStateChanged(ItemEvent e) {
            int value =  e.getStateChange();
      if(1==value)
           System.out.println(">>>>>>>>>"+ comboBox.getSelectedItem().toString());
           
        }
    });
/*    checkBox.addActionListener(new ActionListener() {
