Methods with loops are destroying my brain, help!

Question

Define the method printValues() that takes two integer parameters and outputs all integers starting with the first and ending with the second parameter in reverse order, each followed by a newline. The method does not return any value.

Ex: If the input is 3 7, then the output is:

7

6

5

4

3

import java.util.Scanner;

public class ValuePrinter {

/* Your code goes here */

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

int numberA;

int numberB;

numberA = scnr.nextInt();

numberB = scnr.nextInt();

printValues(numberA, numberB);

}

}

I have a general idea of what to code, but I honestly don't understand how the input/output works in this question. Below is all I have an idea of.

public static void printValues (int numberA, int numberB) {

}

Answer 1

I think your main problem is that you aren't quite understanding the question so let me try to tackle that. I hope this is helpful.

The code given takes input from the user of the program but there is no additional input required in your function. The inputs are the two numbers: numberA and numberB.

Your function is supposed to print all of the integers starting at numberB counting down to numberA. So if numberA is 1000 and numberB is 1005, your function should print the following:

1005

1004

1003

1002

1001

1000

You might want to consider using a for loop in your implementation of the printValues function.
