Using do-while loop, Write a program that will ask for five (5) integer numbers. Determine the highest and lowest value. Consider the sample output.

Output:

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

I honestly don't know how to answer this since my professor haven't discussed about determining the numbers using a do while loop. So far, here's what I have

Edit: I ended up with this code but I don't know how to make the 1st 2nd 3rd 4th 5th show up.

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);
    
    }
}

Some homework improvements to meet the requirements:

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();
        }
    }
}

Please do some research before asking a question like this. While-Loops are well documented all over the internet. That said, this should probably work (haven't tested it though):

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  ;
    }
}
