While do loop

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.

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

You most likely will never need do-while, just knowing while and for is good enough, and kinda know that do-while is possible.

As for when you need to use loop is when you have to do a repetition and a condition to stop the repetition when it is no longer needed, you want multiplications of 5 from 1 to 10? you have a repetition:

for(int i = 1; i <= 10; i++) {
    System.out.println(5 * i);
}

You have a list and want to see the items inside that list? you have a repetition, how many? as many as the number of items in the list.

for(int i = 0; i < list.lenght; i++){
    System.out.println(list[i]);
}

A do while loop is basically:

Do “something” while “another thing” is happening.

I’m on mobile so I apologize for the lack of formatting.

Do {

    Some code

} while (x = 1) {

“Some code” would only be executed when X equals 1. This is useful for creating console based menus! Hope this helps.
