java - 循环错误 - 修复循环意味着破坏其他东西，反之亦然

Question

我一直在努力处理这个循环分配。我可以使程序按预期工作，但是，如果用户未输入值，则代价是在末尾有额外的文本。如果我编写代码以使未输入值的用户没有此额外文本(即最大数字为 0 并且最大数字的计数为 0)，则循环不起作用。我的代码包含在下面。这是怎么回事？

import java.util.Scanner;

public class lab4b_hmcka
{
    public static void main (String [] args)
    {
    //variables
    int num1, num2, max1 = 0, max2 = 0, count = 0, maxCount = 0;

    System.out.println("          Find the maximum number");
    System.out.println();

    System.out.print("Enter an integer <0 ends the input>: ");
    Scanner input = new Scanner(System.in);
    num1 = input.nextInt();

    if (num1 ==0)
    {
        System.out.println("No numbers are entered except 0");
    }

    while (num1 != 0)
    {
        if (maxCount == 0)
        {
            System.out.print("Enter an integer <0 ends the input>: ");
            num2 = input.nextInt();
            max1 = Math.max(num1, num2);
            maxCount = maxCount + 1;
            count = count + 1;
            System.out.print("Enter an integer <0 ends the input>: ");
            num1 = input.nextInt();
            continue;
        }
        else
        {
            max2 = Math.max(num1, max1);

            if (num1 == max1)
            {
                maxCount = maxCount + 1;
                count = count + 1;
            }
            else
            {
                count = count + 1;
            }
            System.out.print("Enter an integer <0 ends the input>: ");
            num1 = input.nextInt();
        }


    }

        if (count == 1)
            {
            System.out.println("The maximum number is " + max1);
            }
        else
            {
            System.out.println("The maximum numberis " + max2);
            }
        System.out.println("The count for the max number is " + maxCount);
    }

}

我不完全确定您想要实现什么以及您试图实现什么(无论是什么)，但我假设您只是想在用户想要立即退出时终止程序(= 首先输入 0)。因此只需添加一个返回即可:

if (num1 == 0) {
    System.out.println("No numbers are entered except 0");
    return; // Terminate now.
}
