我制作了一个简单的应用程序，其中玩家攻击老板，玩家必须尝试击败老板。我遇到的麻烦是在老板被击败后打印我的小型 Java 应用程序。我老板的生命值为 5，我有一个随机骰子生成器，范围为 1 - 6。当玩家在第一次攻击中掷出“5”或“6”时，我希望程序结束。另一件事是我的程序打印出我已经击败了老板，即使玩家没有造成 5 或 6 点伤害。我认为这可能是因为 for 循环，但我不确定。

这是代码：

import java.util.Scanner;
import java.util.Random;

public class Hey{
    public static void main (String args[]){

        Scanner attack = new Scanner(System.in);
        Random dice = new Random();

        String hits;
        int hitss,total = 0;

        System.out.println("Time to attack the boss!");
        System.out.println("Press letter 'A' to attack!");
        hits = attack.next();
        hitss = 1+dice.nextInt(6);

        for(int i=0;i<2;i++){

        if(hits.equals ("a")){

            System.out.println("You have hit a " + hitss);
            total += hitss;
        }
        if(total >= 5){
            System.out.println("Well done, You have defeated the boss!");

        }
        else if(total < 5){
            total = 5 - total;
             System.out.println("You need " + total + " more hits to defeat the boss!");

        }

        else
        {
             System.out.println("Sorry, you did not defeat the boss");
        }

        }
    }
}

输出：

You have hit a 2
You need 3 more hits to defeat the boss!
You have hit a 2
Well done, You have defeated the boss!

你没有关闭扫描仪。

你不打败老板的测试必须在 for 循环之外。

您需要一个不同的变量（更多）来查看剩下的点击量。

如果您在第一轮中获胜，则需要跳出 for 循环。

这是您的代码以及我的更改

import java.util.Scanner;
import java.util.Random;

public class Hey {
    public static void main(String args[]) {

        Scanner attack = new Scanner(System.in);
        Random dice = new Random();

        String hits;
        int hitss, total = 0;

        System.out.println("Time to attack the boss!");
        System.out.println("Press letter 'A' to attack!");
        hits = attack.next();
        hitss = 1 + dice.nextInt(6);

        for (int i = 0; i < 2; i++) {
            if (hits.equals("a")) {
                System.out.println("You have hit a " + hitss);
                total += hitss;
            }
            if (total >= 5) {
                System.out.println("Well done, You have defeated the boss!");
                break;
            } else {
                int more = 5 - total;
                System.out.println("You need " + more
                        + " more hits to defeat the boss!");

            }

        }
        if (total < 5) {
            System.out.println("Sorry, you did not defeat the boss");
        }
        attack.close();
    }
}
