第9题：
请完成下列Java程序：实现2个下拉式菜单，一个包含exit菜单项，另一个包含item1和item2共2个菜单项。要求选择exit菜单项时，退出程序；选择item1菜单项之后，item1项变为不可选而item2可选；选择item2菜单项时，item2变为不可选而item1可选。
注意：请勿改动main()主方法和其他已有语句内容，仅在下划线处填入适当的语句。
程序运行结果如下：
import java.awt.*;
import java.awt.event.*;
public class ex18_2 extends Frame. implements ActionListener {
private choiceHandler ch;
private MenuItem item1;
private MenuItem item2;
public static void main(String[] arg) {
new ex18_2 ( );
}
ex18_2 ( ) {
setTitle("ex18_2");
MenuItem item;
ch = new choiceHandler();
MenuBar mb = new MenuBar();
Menu fm = new Menu("File");
fm.addSeparator();
fm.add(item = new MenuItem("Exit"));
item.addActionListener(this);
fm.add(item);
mb.add(fm);
Menu mm = new Menu("Choice");
mm.add(item1 = new MenuItem("item1"));
item1.addActionListener(ch);
mm.add(item2 = new MenuItem("item2"));
item2.addActionListener(ch);
mb.add(mm);
setMenuBar(mb);
setSize(200,200);
show();
}
public void actionPerformed(ActionEvent ae) {
if(ae.getActionCommand().equals("Exit"))
System.exit(0);
else
System.out.println(ae.getActionCommand());
}
class choiceHandler implements ActionListener {
public void actionPerformed(ActionEvent ae) {
String strCommand = ae.getActionCommand();
if(_________________) {
item2.setEnabled(true);
item1.setEnabled(false);
} else if(______________________) {
item2.setEnabled(false);
