    <p>I'm a novice programmer. This may be a simple problem but I've never seen this before. First of all, let me clarify that I'm not even trying to manipulate the index. Here's the part of the code that is causing the exception:</p> <pre><code> int[] bumpercatcher = new int[4]; //time variable that helps control events int time = 0; public void setup() { bumpercatcher[0]=4; bumpercatcher[1]=4; bumpercatcher[2]=4; bumpercatcher[3]=4; </code></pre> <p>As you can see I'm trying to set them all equal to 4 at the start of the program. This causes the arrayindexoutofbounds exception. If I set them all equal to 0~3 then there is no problem (until I set them to a value greater than 3 later in the program). I don't understand it.</p> <p>-it doesn't matter if I set the array size to 10, I still get the same exception</p> <p>-it doesn't matter if I set only one of the values (i.e. at index 1, which is <strong>definitely</strong> within bounds of the array). same exception</p> <p>Is there something I'm doing wrong? Thanks.</p> <p>well, here' the entire code if you want to take a look(not too long, 1 class, bad programming practies): <a href="http://dl.dropbox.com/u/33501308/Pong.java" rel="nofollow">http://dl.dropbox.com/u/33501308/Pong.java</a></p> <p>Here's the html from which you can see the program from (not much to see. it just freezes instantly.): <a href="http://dl.dropbox.com/u/33501308/bin.zip" rel="nofollow">http://dl.dropbox.com/u/33501308/bin.zip</a></p> <p>by the way I'm using eclipse.</p> <p>I don't really know what SSCEE is. sorry</p>

    1. COPlease show the code where the Exception appeared.

    2. COIt almost sounds like somewhere you are using an element's value as an index. Sort of like `int x = bumpercatcher[0]; int someOther = bumpercatcher[x];`. But your code as presented should have no problems, we'll need to see a bit more where the exception is actually happening.

    3. COIt happens exactly when I set those variables, the program just freezes there. And this part is where I initialize everything.

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.
