    <p><strong>EDIT:</strong></p> <p>It seems as though I have not been clear enough in what I'm asking for, I'm going to try to explain better.</p> <p>I have a class called <code>Board</code></p> <p>This class will have a 2-dimensional array filled with integers, each integer value in the array corresponds to some class (so 1 could be short-hand for String for example).</p> <p>This class will also have some means to take this 2-dimensional array, loop over it and create new instances of some classes.</p> <p>I need to be able to customize what the 2-dimensional array and what classes the different integers corresponds to.</p> <p>I did a little image to try to visualize what I want: <a href="http://i.imgur.com/bZXrw.png" rel="nofollow">http://i.imgur.com/bZXrw.png</a></p> <p>Along with some pseudo-code:</p> <pre><code>class Board: Integer[][] some_array = {{1,2,1},{1,2,1}} someStructure = {1 : createThing, 2 : createSomeOtherThing}; generateObjects(): List[Thing] container = [] for y in some_array: for x in y: container.add(someStructure[x]()) return container </code></pre> <p><strong>OLD FORMULATION:</strong></p> <p>I have a class called <code>Map</code> which is supposed to contain an <code>Integer[][]</code> object, the values inside the Integer array object corresponds to some object which will need to be initialized.</p> <p>Now, in a language like Python I could for example have a dictionary which has some integer values as keys and some functions which creates and returns new objects when called and then loop over a 2d-list and call the functions returned by the dict. How would I go about to do this with Java? </p> <p>I though about having a HashMap and doing some kind of reflection but I don't really know what to do tbh.</p>

    2. COSo the goal here is to go through the array and every time you see 1 you call function1(), 2: function2() etc? If so, is there a reason to not use a switch statement?

    3. COWell, a switch-case would be fine if I wouldn't have several objects which has different requirements and integer values.

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.
