怎么用JAVA在一個(gè)程序里面創(chuàng)建多個(gè)圖形界面窗口？

創(chuàng)建一個(gè)窗口程序（JFrame），標(biāo)題欄起名為“瀏覽器”，有一個(gè)菜單條，有“文件”、“編輯”、“查看”3個(gè)菜單。“文件”菜單有兩個(gè)菜單項(xiàng)，一項(xiàng)是“打開”，一項(xiàng)是“保存”，“打開”項(xiàng)做成子菜單，有兩個(gè)菜單項(xiàng)“打開x”和“打開y”，“保存”項(xiàng)就是普通的菜單項(xiàng)。“編輯”菜單就一個(gè)菜單項(xiàng)“復(fù)制”。“查看”有兩個(gè)菜單項(xiàng)“停止”和“刷新”。在菜單及菜單項(xiàng)上添加合適的快捷鍵。

package 窗口;

import javax.swing.*;

import java.awt.*;

import java.awt.event.KeyEvent;

import java.awt.event.InputEvent;

public class Text {

public static void main(String[] args) {

JFrame a=new JFrame("瀏覽器");//頂層容器

JMenuBar b=new JMenuBar();//菜單條

JMenu c=new JMenu("文件A");//菜單

c.setMnemonic('A');

//c.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_A,InputEvent.CTRL_MASK));

JMenu d=new JMenu("編輯B");//菜單

d.setMnemonic('B');

//d.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_B,InputEvent.CTRL_MASK));

JMenu e=new JMenu("查看C");//菜單

c.setMnemonic('C');

//e.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_C,InputEvent.CTRL_MASK));

JMenuItem f=new JMenuItem("保存");//菜單項(xiàng)

f.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_D,InputEvent.CTRL_MASK));

JMenu g=new JMenu("打開");//子菜單

//g.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_E,InputEvent.CTRL_MASK));

JMenuItem h=new JMenuItem("打開x");//菜單項(xiàng)

h.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_F,InputEvent.CTRL_MASK));

JMenuItem i=new JMenuItem("打開y");//菜單項(xiàng)

i.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_G,InputEvent.CTRL_MASK));

JMenuItem j=new JMenuItem("復(fù)制");//菜單項(xiàng)

j.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_H,InputEvent.CTRL_MASK));

JMenuItem k=new JMenuItem("停止");//菜單項(xiàng)

k.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_I,InputEvent.CTRL_MASK));

JMenuItem l=new JMenuItem("刷新");//菜單項(xiàng)

l.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_G,InputEvent.CTRL_MASK));

g.add(h);

g.add(i);

c.add(g);

c.add(f);

d.add(j);

e.add(k);

e.add(l);

b.add(c);

b.add(d);

b.add(e);

a.setJMenuBar(b); //將菜單條加入窗口

a.setBounds(260,100,188,108);

a.setVisible(true);

a.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

}
