这期内容当中小编将会给大家带来有关利用Java编写一个俄罗斯方块小游戏，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。
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;
public Tetris() {
// 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
JMenuBar menubar = new JMenuBar();
setJMenuBar(menubar);
// 菜单
JMenu menuGame = new JMenu("游戏");
menubar.add(menuGame);
// 菜单项
JMenuItem mi1 = new JMenuItem("新游戏");
mi1.setActionCommand("new");
JMenuItem mi2 = new JMenuItem("暂停");
mi2.setActionCommand("pause");
JMenuItem mi3 = new JMenuItem("继续");
mi3.setActionCommand("continue");
JMenuItem mi4 = new JMenuItem("退出");
mi4.setActionCommand("exit");
menuGame.add(mi1);
menuGame.add(mi2);
menuGame.add(mi3);
menuGame.add(mi4);
//菜单项监听
MenuListener menuListener = new MenuListener();
mi1.addActionListener(menuListener);
mi2.addActionListener(menuListener);
mi3.addActionListener(menuListener);
mi4.addActionListener(menuListener);
// 版本菜单
JMenu menuHelp = new JMenu("帮助");
menubar.add(menuHelp);
menuHelp.add("版本所有@湖南城院 QQ:666688888");
setLocation(700, 200);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(220, 275);
setResizable(false);
tp = new TetrisPanel();
getContentPane().add(tp);
// 让整个画布添加键盘监听
// tp.addKeyListener(tp.listener);//不行,画布不方便获得键盘焦点
this.addKeyListener(tp.listener); // 让框架来监听键盘
}
public static void main(String[] args) {
Tetris te = new Tetris();
te.setVisible(true);
}
class MenuListener implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().equalsIgnoreCase("new")){
getContentPane().remove(tp);
