java 如何用用数组设置一个窗体的三级菜单？这不简单吗java多级菜单代码，直接循环加上去就可以java多级菜单代码了 。
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class List extends JFrame{
public List(){
initialization();
setTitle("三级菜单");
setBounds(300,300,400,300);
setLayout(null);
Container c=getContentPane();
setVisible(true);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
public void initialization(){
JMenu jmenuTwo=null;
String[] menubar={"编辑","帮助"};
String[][] submenu={{"复制","粘贴","","历史记录"},{"关于三级菜单"}};
String[] threemenu={"撤消","恢复"};
JMenuBar jmenubar=new JMenuBar();//创建菜单栏
for(int i=0;imenubar.length;i++){
JMenu jmenu=new JMenu(menubar[i]);
jmenubar.add(jmenu);
for(int j=0;jsubmenu[i].length;j++){
if("".equals(submenu[i][j])){
jmenu.addSeparator();//添加一条横线
}else{
jmenuTwo=new JMenu(submenu[i][j]);
