无限循环：如果您输入数字 1、3、5，我的 Mastermind 程序会创建一个无限循环

Question

每次输入数字 1、3、5 时都会出现无限循环，我不知道如何解决。这是一个使用数组的策划程序，其中使用钉子而不是数字。问题很可能出在 while 循环中，在该循环中进行了更改以使程序更加简洁。任何帮助都会很棒。

package New;
import java.util.Random;

import New.ArrayMethod2;
import TurtleGraphics.KeyboardReader;

public class Mastermind2 {



    public static void main(String[] args) {
        Mastermind2 object = new Mastermind2();KeyboardReader reader = new KeyboardReader();
    int[] V = new int [3];
    do {

    System.out.println("Please choose your first number (1-5)");
    V[0]=reader.readInt();
    System.out.println("Please choose your second number (1-5)");   
    V[1]=reader.readInt();
    System.out.println("Please choose your third number (1-5)");
    V[2]=reader.readInt();
    }while((V[0]>5)&&(V[1]>5)&&(V[2]>5));
    object.CorrectVariables(V[0], V[1], V[2]);
}
public void CorrectVariables(int num1, int num2, int num3) {
    Mastermind1 object = new Mastermind1();
    int Cornum1, Cornum2, Cornum3;
    Random generator = new Random();
    Cornum1 = generator.nextInt(5)+1;
    Cornum2 = generator.nextInt(5)+1;
    Cornum3 = generator.nextInt(5)+1;
    IFstatements(Cornum1, Cornum2, Cornum3, num1, num2, num3);
}
public void IFstatements(int Cornum1, int Cornum2, int Cornum3, int num1, int num2, int num3) {
    Mastermind1 object = new Mastermind1();
    do{
        int Number=0, Color=0;
        if(Cornum1==num1)
        {
            Number++;
            Color++;
        }
        if(Cornum1==num2)
        {
            Color++;
        }
        if(Cornum1==num3)
        {
            Color++;
        }
        if(Cornum2==num2)
        {
            Number++;
            Color++;
        }
        if(Cornum2==num1)
        {
            Color++;
        }
        if(Cornum2==num3)
        {
            Color++;
        }
        if(Cornum3==num3)
        {
            Number++;
            Color++;
        }
        if(Cornum3==num1)
        {
            Color++;
        }
        if(Cornum3==num2)
        {
            Color++;
        }
        System.out.println("You have "+Number+" numbers correct and "+Color+" colors correct");
        if((Cornum1!=num1)||(Cornum2!=num2)||(Cornum3!=num3));
        {
            Number=0;
            Color=0;
        }
    }while((Cornum1!=num1)&&(Cornum2!=num2)&&(Cornum3!=num3));
    System.out.println("Congrats you guessed the correct numbers");
}

}

Answer 1

您的 IFStatements 函数的退出条件似乎是用户的输入与正确的模式匹配。但是，用户没有机会更新他的输入，并且您永远不会更改 num 或 Cornum 变量以匹配正确的输出。因此，循环将永远继续执行。您需要做的是让该代码运行一次，然后让用户有机会更新他们的答案。

Answer 2

public static void main(String[] args) {
    Mastermind2 object = new Mastermind2();
    Scanner scan = new Scanner(System.in);
    int one = getNumber("first", scan);
    int two = getNumber("second", scan);
    int three = getNumber("third", scan);
    object.correctVariables(one, two, three);
}

private static int getNumber(String str, Scanner scan) {
    while (true) {
        System.out.print("Please choose your " + str + " number (1-5): ");
        int num = scan.nextInt();

        if (num >= 1 && num <= 5)
            return num;
    }
}

public void correctVariables(int one, int two, int three) {
    Random random = new Random();
    int expectedOne = random.nextInt(5) + 1;
    int expectedTwo = random.nextInt(5) + 1;
    int expectedThree = random.nextInt(5) + 1;
    ifStatements(expectedOne, expectedTwo, expectedThree, one, two, three);
}

public void ifStatements(int expectedOne, int expectedTwo, int expectedThree, int one, int two, int three) {
    int num = expectedOne == one ? 1 : 0;
    num += expectedTwo == two ? 1 : 0;
    num += expectedThree == three ? 1 : 0;

    int color = expectedOne == one ? 1 : 0;
    color += expectedOne == two ? 1 : 0;
    color += expectedOne == three ? 1 : 0;

    color += expectedTwo == one ? 1 : 0;
    color += expectedTwo == two ? 1 : 0;
    color += expectedTwo == three ? 1 : 0;

    color += expectedThree == one ? 1 : 0;
    color += expectedThree == two ? 1 : 0;
    color += expectedThree == three ? 1 : 0;

    System.out.println("You have " + num + " numbers correct and " + color + " colors correct");

    if (num == 3)
        System.out.println("Congrats you guessed the correct numbers");
}
