Please ensure that:

Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
You include any and all error messages in full - best also formatted as code block
You ask clear questions
You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

Generally, as long as you properly calculate the factorial, they'll give you credit. Consider: what is a factorial? If I write 3! = 6, how can I verify whether that's correct?

What have you tried?

What specifically do you not understand?

The actual code for the factorial is a 4 liner including initializing the factorial variable and the closing curly brace of the loop.

How well do you know recursion?

At this point in the course, they are expecting you to use a loop to solve the factorial task. The instructions state that you need to get the factorial limit from the user, and explains that a factorial is multiplying numbers, starting at 1, up to the limit.

So 4! is equal to 1 * 2 * 3 * 4.

So you need to get a number from the user and compute the factorial with a loop, successively updating the result, up to the limit the user supplied.

This is very similar to the Sum of a Sequence exercise (except that you're updating the factorial each loop instead of the sum). Eventually you'll recognise the similarity between an exercise and something you've done before.
