I am stuck on this question and I am in need of assistance

Question about the task

Resolved

I am confused on how I should write this code for some reason. I understand what the code is asking me, yet I don't know what I am doing. I must be overthinking this. Can anyone help me? Thank you and have a great rest of your day!

The main method reads 3 integers from the keyboard: start, end, and multiple.
Update the program so that the screen displays the sum of all numbers in the range from start (inclusive) to end (not inclusive) that are evenly divisible by the multiple variable.
Use a for loop to do this.
Hint: To move to the next iteration of the loop, use a continue statement.

Requirements:

The program should display the sum of all numbers in the range from start (inclusive) to end (not inclusive) that are evenly divisible by the multiple variable.
The program must use a for loop.
You must use a continue statement in a for loop.

package en.codegym.task.pro.task04.task0412; import java.util.Scanner; /* Sum of even numbers */ public class Solution { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int start = scanner.nextInt(); int end = scanner.nextInt(); int multiple = scanner.nextInt(); int sum = 0; for (int a = 1; a >= start && a < end; a++) { if (end % multiple == 0) { a++; continue; } sum = a + sum; } System.out.println(sum); } }

I didn't do the pro tasks, but the way that I read this is first take the three numbers. Think of the first 2 as the start and end of a number line. The third number is the "step" of numbers to sum up in that line. Example :Lets say I entered 8, 27, 4 The first 2 numbers determine the number line:

8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
        ↑           ↑           ↑           ↑

while the third is telling us to sum up every 4th number so the 4th, 8th, 12th, and 16th numbers (the numbers in that line 11, 15, 19, and 23 as marked). So, if I am correct in my assessment of the conditions, the answer would be achieved by summing those up and coming to 68.

Re-reading it I think they are asking you to sum up any numbers in the range that are a multiple of the third entered number. So in the example I gave it would be 8, 12, 16, 20, and 24 (all multiples of 4 in that range) for a total of 80.

I understand what you are trying to say, and I appreciate the detailed explanation and examples, yet I still don't understand how to incorporate the condition into a functional code, which is the problem I am trying to solve.

solution

That is simple. The first entered number is the start counter of the loop and what you will add 1 to each loop cycle. The second entered number is the condition where the loop continues running until reached. The third entered number is what you need to check the current counter against as a multiple:

for(first number; first number < second number; first number++) {
    if(check if first number is not multiple of third number) continue;
    add first number to sum
}

Thank you! I finally figured it out. I wasn't that hard, I was just dumb and couldn't put the puzzle together. 🤣 I appreciate it.
