 THE DETAILS ARE AS FOLLOWS:
 THE classes apartmentblock and estate are classes within the class apartments.the main function is executed in the class cat1. how do i add  a new apartmentblock to the estate and how do i use arrays in the code

In your Estate class you can declare and initialise a simple array of ApartmentBlocks. Then you can have a public method that takes an ApartmentBlock as a parameter and puts it into the array. It's not hard, so just have a go and see how you get on.

after creating the array inside the estste how do i use the add method to add a new apartment block
