Java使用do-while循环

Question

使用do-while循环，编写一个程序，请求5 (5)个整数。确定最高值和最低值。考虑示例输出。

输出：

Enter 1st number: 5
Enter 2nd number: 10
Enter 3rd number: 2
Enter 4th number: 50
Enter 5th number: 30

The highest value is: 50
The lowest value is: 2

老实说，我不知道该如何回答这个问题，因为我的教授还没有讨论过用do while循环来确定数字。到目前为止，我有的是

编辑:我最后得到了这个代码，但我不知道如何使第一，第二，第三，第四，第五次出现。

enter code here

public static void main(String[] args) {
    // TODO Auto-generated method stub
    Scanner inp=new Scanner(System.in);
    int a = 1;
    int i =1;
    int highestNumber=0;
    int lowestNumber=0;
    
    while (i < 5) {
        System.out.println("Enter " + a++ +" number ");
        int numbers = inp.nextInt();
        
    
        if(highestNumber==0) {
            highestNumber = numbers;        
        }else if(numbers>highestNumber) {
            highestNumber=numbers;          
        };
        
        if(lowestNumber==0) {
            lowestNumber = numbers;     
        }else if(numbers<lowestNumber) {
            lowestNumber=numbers;           
        };
        
        System.out.println("The Highest Number is: " + highestNumber);
        System.out.println("The Lowest Number is: " + lowestNumber);
    
    }
}

Answer 1

一些作业改进以满足要求：

import java.util.*;

public class Main {
    public static void main(String[] args) {
        String[] nums = new String[] {"1st", "2nd", "3rd", "4th", "5th"};

        try(Scanner inp = new Scanner(System.in)) {

            int min = Integer.MAX_VALUE;
            int max = Integer.MIN_VALUE;
            
            int i = 0;
            do{

                System.out.print("Enter " + nums[i] + " number: ");
                int num = inp.nextInt();

                if(num < min) min = num;
                if(num > max) max = num;

            } while(++i < nums.length);

            System.out.println("\nThe highest value is: " + max);
            System.out.println("The lowest value is: " + min);

        } catch(InputMismatchException e) {
            e.printStackTrace();
        }
    }
}

在提出这样的问题之前，请先做一些调查。而-循环在互联网上有很好的记录。尽管如此，这可能是可行的(虽然还没有测试)：

public static void main(String[] args) {
    Scanner inp=new Scanner(System.in);
    int[] numbers = new int[5];
    int i = 0;
    
    while (i < numbers.length) {
        System.out.println("Enter number " + i);
        numbers[i] = inp.nextInt();
        i++;
    }
}
