The last one and the current. I want to show all the ids as far as the user wants. Not infinite of course. So how can i create an arraylist, lets say with ten values, and store the id each time?</p>

    1. COuse a static arraylist and be sure about getting the ID's.

    2. COYou say that i should create an arraylist with ten values(null) and then replace them? How can i replace values with specific idex inside the arraylist?

    3. CONo, only use static key before the arraylist :) static ArrayList<String>. On the other hand, you can do what you said, because you add values to index which you have selected.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
