Java ：swing界面

常规菜单：

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;

public class J_Menu extends JFrame{
	public J_Menu(){
		super("常规菜单例子");
		JMenuBar mBar = new JMenuBar();
		setJMenuBar(mBar);//设置菜单栏
		
		J_Menu [][] m={ new JMenu("文件(F)"),new JMenu("编辑(E)")};
		char [][] mC = { {'F','E'},{'O','S'},{'C','V'}};
		JMenuItem [][] mI ={
			{new JMenuItem("打开(O)"),new JMenuItem("保存(S)")},
			{new JMenuItem("复制(C)"),new JMenuItem("粘贴(V)")}
		};
		int i,j;
		for(i=0;i< m.length;i++){
			mBar.add(m[i]);//添加下拉式菜单
			m[i].setMnemonic(mC[i][j]);//设置助记符
