java 中实现如果进攻时枪里没子弹，则自动装载子弹

public class AK47 {
public int bullets=100;
public void fire() {
if(bullets==0) {
System.out.println("枪里无子弹");
return;
}
int r=new Random().nextInt(10);
if (r > bullets) {
r=bullets;
}
bullets -=r;
for(int i=0;i<r;i++) {
System.out.print("轰");
}
System.out.println("~");
if(bullets==0) {
System.out.println("弹药已空");
}
}
public void load() {
bullets = 100;
System.out.println("弹夹已满");
}

}
对此代码进行升级，自动装弹

public class AK47
{
    private int bullets = 100;

    public static void main(String[] args) throws InterruptedException
    {
        AK47 ak = new AK47();
        while (true)
        {
            if (ak.bullets == 0)
            {
                System.out.println("弹药已空");
                ak.load();
            }
            ak.fire();
            Thread.sleep(200);
        }
    }

    public void fire()
    {
        int r = new Random().nextInt(10) + 1;
        if (r > bullets)
        {
            r = bullets;
        }
        bullets -= r;
        for (int i = 0; i < r; i++)
        {
            System.out.print("轰");
        }
        System.out.println("~");
    }

    public void load() throws InterruptedException
    {
        bullets = 100;
        System.out.println("正在重新装弹...");
        Thread.sleep(3000);
    }
}

public class AK47 {
public int bullets=100;
public void fire() {
if(bullets==0) {
load();
System.out.println("枪里无子弹");
return;
}
int r=new Random().nextInt(10);
if (r > bullets) {
r=bullets;
}
bullets -=r;
for(int i=0;i<r;i++) {
System.out.print("轰");
}
System.out.println("~");
if(bullets==0) {
System.out.println("弹药已空");
}
}
public void load() {
bullets = 100;
System.out.println("弹夹已满");
}

public static void main(String[] args) {
    AK47 ak47 = new AK47();
    for (int i = 0; i < 100; i++) {
        ak47.fire();
    }
}
