敌人飞机类，因为后面还想做些关卡弄不同的飞机，所以加了个飞机类型，线程根据不同的飞机类型类控制移动的规则

package Game;
    
    import java.util.Vector;
    
    import javax.swing.ImageIcon;
    
    public class FoeFly extends Fly implements Runnable{
    	public Vector<FoeFly> foeFlyArr;
    	public ImageIcon img;
    	public int type; //敌人飞机类型
    	public FoeFly(){
    		foeFlyArr = new Vector<>(); //实例化敌人飞机集合
    	}
    	public FoeFly(int x, int y, int hp, boolean doom, int type, String path){
    		super(x,y,hp,doom);
    		this.type = type;
    		img = new ImageIcon(path);
    	}
    	@Override
    	public void run() { //敌人飞机移动线程
    		while (true){
    			try {
    				Thread.sleep(8);
    			} catch (InterruptedException e) {
    				e.printStackTrace();
    			}
    			
    			for (int i=0; i<foeFlyArr.size(); i++){
    				if (foeFlyArr.get(i).type == 1){ //类型一飞机，直线向下移动
    					if (foeFlyArr.get(i).y > 600){
    						foeFlyArr.remove(i);
    						i--;
    						continue;
    					}
    					foeFlyArr.get(i).y += 1;
    				}
    			}
    		}
    	}
    }

通过一个线程类来创造敌人飞机

package pass;
    
    import Game.FoeFly;
    
    /**
     * 
     * @author Administrator
     *关卡1的创建飞机线程
     */
    public class ProduceNo1 implements Runnable{
    	FoeFly foefly;
    	public ProduceNo1(FoeFly foefly) {
    		this.foefly = foefly;
    	}
    	@Override
    	public void run() {
    		while (true){
    			try {
    				Thread.sleep(2000);//间隔两秒生成一架敌人飞机
    			} catch (InterruptedException e) {
    				// TODO 自动生成的 catch 块
    				e.printStackTrace();
    			}
    			int x = (int)Math.round(Math.random()*350);
    			int y = (int)Math.round(Math.random()*(-20));
    			foefly.foeFlyArr.add(new FoeFly(x,y,40,true,1,"img/Foefly-1.png"));
    		}
    	}
    }

敌人子弹通过线程创建出来（在敌人飞机位置生成）

package Game;
    /**
     * 
     * @author Administrator
     *生成敌人子弹类线程
     */
    public class Pfb implements Runnable{
    	FoeFly foefly;
    	FoeBomb foebomb;
    	public Pfb(FoeFly foefly, FoeBomb foebomb){
    		this.foefly = foefly;
    		this.foebomb = foebomb;
    	}
    	@Override
    	public void run() {
    		while (true){
    			//给每个子弹类在敌人飞机位置生成 子弹
    			for (int i=0 ;i<foefly.foeFlyArr.size(); i++){
    					foebomb.bombarr.add(new FoeBomb(foefly.foeFlyArr.get(i).x+25, foefly.foeFlyArr.get(i).y+50, true,"img/drzd-1.png"));
    			}
    			try {
    				Thread.sleep(1500);
    			} catch (InterruptedException e) {
    				e.printStackTrace();
    			}
    		}
    	}
    
    }

敌人子弹类

package Game;
    
    import java.util.Vector;
    
    import javax.swing.ImageIcon;
    
    /**
     * 
     * @author Administrator
     *敌人子弹线程
     */
    public class FoeBomb extends Bomb implements Runnable{
    	public FoeBomb(){
    		bombarr = new Vector<>();
    	}
    	public FoeBomb(int x, int y, boolean vis, String path) {
    		super(x, y, vis);
    		img = new ImageIcon(path);
    	}
    	@Override
    	public void run() {
    		while (true){
    			try {
    				Thread.sleep(7);
    			} catch (InterruptedException e) {
    				e.printStackTrace();
    			}
    			for (int i=0; i<bombarr.size(); i++){
    				if (bombarr.get(i).y > 600){//超出边界
    					bombarr.remove(i);
    					i--;
    					continue;
    				}
    				bombarr.get(i).y += 1;
    			}
    		}
    	}
    }
