I would honestly appreciate if somebody could explain this to me. I know this is something that can be fixed easily and I don't understand how.

The insertArticles option doesn't actually insert the articles immediately like it is supposed to. It does it AFTER expanding the array, so basically you have to re-type Option 1 and then how many articles you would like to insert.

Isn't that method overwriting articles at the beginning?

#

The thing I don't get is why the code basically adds new articles after like, 2 runs, instead of doing it directly.

#

Do you have any idea? If you could be concrete it would help a lot.

ocean dew
#

it deletes the first few articles and replaces them

#

or not?

Look

  1. Insert articles
  2. Remove an article
  3. Display a list of articles
  4. Register a sale
  5. Display order history
  6. Sort and display order history table.
    q. Quit

    How many articles do you want to add?
    2
    There are not enough free slots.
    I need to expand the array by 2 slots.

i asked to insert 2, and after doing the same process twice it added one new article

#

I use replit

ocean dew
#

in the last article table

#

so it seems like it did insert two article

#

just one is a duplicate

It used to work before with the same code, but when I fixed another method it affected this somehow.

What about the following approach: You first check whether it is full and expand it if necessary and after it, you insert the articles?

# 
    public static int[][] insertArticles(int[][] articles, int noOfArticles) {
        System.out.println("How many articles do you want to add?");
        int numberOfArticles = userInput.nextInt();

        int articlesInserted = 0;
        if (articlesInserted < numberOfArticles) {
            articles = checkFull(articles, numberOfArticles);
        }
        for (int row = 0; row < articles.length && articlesInserted < numberOfArticles; row++) {
            for (int column = 0; column < 3; column++) {
                if (articles[row][column] == 0) {
                    articles[row][0] = articleNumber;
                    articles[row][1] = (int) (Math.random() * 10) + 1;
                    articles[row][2] = 145;
                    articlesInserted++;
                    articleNumber++;
                }
            }
        }

        printArticles(articles);
        return articles; // Return the modified articles array
    }
#

something like that

muted ferry
#

correct

#

You wrote that?

#

Just like now?

muted ferry
ocean dew
#

maybe you need to change articles[row][0] = articleNumber; to articles[row][0] = articleNumber+1;

that can really help you with finding out where the problems are

yeah you should definitely use an IDE
