I wonder what would would happen if u would create a class extending
an array.

class CustomArray extends Object[ ]
{
}

It would be never more useful than implementing List.

class CustomArray implements List {
}

i know, just wondering if it would work

Probably you could override these two methods

public Object operator[](int index);
public void operator[](int index, Object value);

But you could not change the 'length' because it is final.

Errm, we are talking Java here, right ?

I hypothetic Java, you can do anything you want

In real Java, you are very far from being able to extend array
types or overload operators.

You have two problems:

the name of the class is no accessible in ordinary java. You would
have to write byte code.

The class is almost certainly final.

Consider writing an HAS-A rather than IS-A implementation, the way
ArrayList does.

I am not took good at reflection, but would it be possible the change
the size of an array with reflection.

No. If you want to have resizable collections you should go for an
ArrayList or something similar. That's what they are made for.
