    <p>The code needs to be correct really isn't a functional requirement, so its hard to say exactly what is correct without knowing more about your game/map.</p> <p>Assuming you have a map that has X tiles and no ordered adjacency a non-matricial solution is best, a common solution is to just model it like a graph using either adjacency list for non-symmetric adjacency or incidence list for symmetric adjacency. If youre using an incidence list you need an edge object that contain the vertices the edge is connecting, if youre using adjacency list a <a href="http://www.java2s.com/Code/Java/Collections-Data-Structure/MultiMapextendsAbstractMap.htm" rel="nofollow noreferrer">multimap</a> might be cool to use.</p> <p>If you want a non-matricial solution with ordered adjacency AlbertoPL has the solution for that.</p> <p>Assuming you have a map thats X tiles wide and Y tiles tall and the tiles that are next to each other are adjacent, so that each tile has at max 4 and min 2 adjacent tiles you could use a matrix to access the tiles and also represent adjacency by matricial adjacency. The idea is that map[Y][X] is adjacent to map[Y+1][X] and map[Y][X+1] and reversely. This solution could also fit max 6 and min 3 tile adjacency if tile [Y+1][X+1] is adjacent to tile [Y][X]. Upside to this is that you can easily parse the map, and since it has 2 dimensions its natural to model it like this. Downside is that once a tile is set, you cant change its adjacency without changing the matrix. As this isnt what you professor suggested you might not want to do it, but if you have (static) ordered adjacency this might be easiest way to do it.</p>

    1. COThe beginning idea was to use an adjacency list. Right now I'm trying to make Alberto's way work. I understood your method btw, so thank you! ^_^

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.
