Remember the Illustration of the four families as shown in the picture above? Click here to refresh you memory. I explained that family “A” member can call members of families B, C and D and vice versa. Today, I will be explaining how this could be achieved, I promised three things in my last post on package: 1.)How to make a class callable outside its package, 2.)The import statement and 3.) The different styles of import. Hence, to fulfill my promise I will be providing answers to these key points today.
