Answer 1

Where you declare the myclass[] array as :

xClass myclass[] = new xClass[10]

, simply pass in as an argument the number of XClass elements you'll need. At that point do you know how many you will need? By declaring the array as having 10 elements, you are not declaring 10 XClass objects, you're simply creating an array with 10 elements of type xClass.
