import java.awt.Button ;
import java.awt.Menu ;
import java.awt.MenuBar ;
import java.awt.MenuItem ;
import java.awt.Frame ;
import java.awt.event.ActionEvent ;
import java.awt.event.ActionListener ;
import java.awt.event.WindowAdapter ;
import java.awt.event.WindowEvent ;

public class calculator extends Frame implements ActionListener
{
private Frame F = new Frame() ;
private MenuBar menubar = new MenuBar() ;
private Menu menu = new menu("菜单") ;
private MenuItem mNew = new MenuItem("新建") ;
private MenuItem mExit = new MenuItem("退出") ;
private Button m1 = new Button("1") ;
private Button m2 = new Button("2") ;
private Button m3 = new Button("3") ;
private Button m4 = new Button("4") ;
private Button m5 = new Button("5") ;
private Button m6 = new Button("6") ;
private Butt

帮你修改好了，逻辑还得靠自己实现！

import java.awt.Button ;
import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.Menu ;
import java.awt.MenuBar ;
import java.awt.MenuItem ;
import java.awt.Frame ;
import java.awt.event.ActionEvent ;
import java.awt.event.ActionListener ;

import javax.swing.JFrame;

public class calculator extends JFrame implements ActionListener
{
private Frame F = new Frame() ;
private MenuBar menubar = new MenuBar() ;
private Menu menu = new Menu("菜单") ;
private MenuItem mNew = new MenuItem("新建") ;
private MenuItem mExit = new MenuItem("退出") ;
private Button m1 = new Button("1") ;
private Button m2 = new Button("2") ;
private Button m3 = new Button("3") ;
private Button m4 = new Button("4") ;
private Button m5 = new Button("5") ;
private Button
