    1. COThe exception: (copy & paste) `java.lang.InstantiationException: generics.MyClass` `at java.lang.Class.newInstance0(Unknown Source)` `at java.lang.Class.newInstance(Unknown Source)` `at generics.CoolArray.<init>(CoolArray.java:14)` `at generics.CoolArrayTest.create(CoolArrayTest.java:12)` `at generics.CoolArrayTest.main(CoolArrayTest.java:6)` I couldn't get anything from that :)

    2. COI am really grateful for your enthusiasm towards solving my problem! But I just posted the solution to my problem myself. You are right again, i meant `InstantiationException` and it looked like `java.lang.InstantiationException: generics.MyClass`. It pointed to the line where I call `array[ i ] = clazz.newInstance();` That's why I figured that there must be something wrong in that line but it was the constructor of my class that led to that error. My detailed explanation below should leave no questions.

    3. COThank you for your answer! Well, you are not correct with the ArrayList part. I didn't want to use ArrayLists because of the performance issue when inserting and removing elements. Especially when called multiple times each frame from *update()* and *render()*. Well, I didn't mean I solved the `NullPointerException` I just wanted to know what I have to write there to make it work. You are absolutely right, it is `array[i].newInstance()`. But when I wrote that, I got an `InstantiationError`. That is the one I wanted to get fixed.

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.
