    <p>I know what a static array is and how to use it in Java, but my Prof assigned us a program and for one of the many classes we had to create, he asked us to 'use a static array' in such a way that multiple objects will store their data there.</p> <p>For instance, if the objects were car garages, then each garage instance would store in a 100x3 static array their data:</p> <pre><code> 1, honda, four-door 3, toyota, two-door 1, bicycle, -1 1, ford, pickup 2, ford, fiesta 3, chevy, two-door 3, bicycle, -1 </code></pre> <p>The -1 indicates the end of each garage.</p> <p>That's a lousy example, but you get the idea.</p> <p>So, I am thinking that what he wants is kind of like this:</p> <p>In the demo class (which is the main), I will declare an instance of a class I made with the static array in it:</p> <pre><code> PublicAccessArray p1 = new PublicAccessArray(); </code></pre> <p>Then that class starts off like: </p> <pre><code> public class PublicAccessArray { public static int[][] accessArray; public static void PublicAccessArray() { accessArray = new int[100][3]; ... </code></pre> <p>And then my class that will create the objects to use the static array will look like:</p> <pre><code> public class ClassThatUsesTheStaticArray { public void ClassThatUsesTheStaticArray (PublicAccessArray array1) {... </code></pre> <p>So then back in the demo/main class I would instantiate those objects with:</p> <pre><code> ClassThatUsesTheStaticArray c1= new ClassThatUsesTheStaticArray (p1); </code></pre> <p>I think that's what he means, and I know that the static array should look like the example I gave (though it uses numbers as data/elements).</p> <p>I know he wants us to instantiate the ClassThatUsesTheStaticArray objects from the demo/main class and the only way I can see to do that would be to pass the p1 array to it.</p> <p>Does what I am doing seem to be the right way? I often an easier time doing the actual coding than figure out what my Prof. is actually asking us to do so I was wondering if that sounds like a way to 'use a static array'.</p>

    1. COI think the underlying idea idea is to use the static array as a database, of sorts.

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.
