Java游戏俄罗斯方块的实现实例

java小游戏主要理解应用java Swing,awt等基础组件的知识，通过本例应当掌握面向对象的知识。

实现代码：

package cn.hncu.games;

import java.awt.Color;

import java.awt.Font;

import java.awt.Graphics;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.KeyAdapter;

import java.awt.event.KeyEvent;

import javax.swing.JFrame;

import javax.swing.JMenu;

import javax.swing.JMenuBar;

import javax.swing.JMenuItem;

import javax.swing.JOptionPane;

import javax.swing.JPanel;

import javax.swing.Timer;

public class Tetris extends JFrame {

private TetrisPanel tp;

// 添加菜单，这里只是意思一下，留待大家自己做更详细的

// 菜单条

//菜单项监听

mi1.addActionListener(menuListener);

mi2.addActionListener(menuListener);

mi3.addActionListener(menuListener);

// 版本菜单

JMenu menuHelp = new JMenu("帮助");

menubar.add(menuHelp);

setLocation(700, 200);

setDefaultCloseOperation(EXIT_ON_CLOSE);

setSize(220, 275);

setResizable(false);

// tp.addKeyListener(tp.listener);//不行,画布不方便获得键盘焦点
