坦克大战
该坦克大战运用了JavaGUI图形库，多线程，文件IO，反射等Java高级编程中的知识，用来巩固Java语法非常合适。 我在韩老师原版的设计上做了一些改变，敌方坦克会永远保持三个，你每杀死一辆敌方坦克，并会在屏幕内随机生成一个敌方坦克以此来增加游戏乐趣，其他内容与原版无异。下面是展示图：
该项目总共九个类，包含近1000行代码。
编程过程中的一些注意事项：
- 坦克爆炸是通过反射实现的，而反射是Java程序在运行时实现的，所以图片应该放在项目的out文件夹下。
- 第一个爆炸图片加载不出来是因为线程刚加载的时候运行速度过快，可以把第一个图片的life放大。
这是我第一次分享项目，有其他问题或不足的欢迎大家在评论区讨论，也可以私聊问我哦。
图示
以上是基本的运行内容，下面是源代码实现：
1.方法入口（TankGame06）
import javax.swing.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.util.Scanner;
public class TankGame06 extends JFrame {
static Scanner scanner=new Scanner(System.in);
private Mypanel mp=null;
public static void main(String[] args) {
new TankGame06();
}
public TankGame06(){
System.out.println("请输入你的选择>:");
System.out.println("1. 开启新游戏 2. 继续上局游戏");
String key=scanner.next();
mp=new Mypanel(key);
Thread thread=new Thread(mp);
thread.start();
this.add(mp);
this.setSize(1300,800);
this.addKeyListener(mp);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
Recorder.keepRecord();
System.exit(0);
}
});
}
}2.坦克类父类（Tank）
