Objects to arrays?
<p>I need to make the following (X and Y are only examples):</p>

<p>I have an X class. In that class I have objects, what I made. I have an another (Y) class, what extends the X class and implements Cloneable. In the X class, which objects I made, need to put them in an array.  Then I need to clone it to the Y class. How can I do it? </p>

<p>Here is the code: </p>
