Time for action – Declaring some fields

Now, imagine that we want to create a class named Person. Its instances should have a public name field, a private age field, and the class should have a static and public count field.

1. The first thing we can do is to write it in the following way:

   class Person
   {
      public var name : String; //This one is public
      var age : Int; //This one is private
      public static var count : Int = 0; //This one is static and initialized at 0
   }

2. On the other hand, we can write it by implementing the Public interface, as follows:

   class Person implements Public
   {
      var name : String; //This one is public
      private var age : Int; //This one is private
      static var count : Int = 0; //And this one is public
   }

What just happened?

These two solutions will result in exactly the same thing:

• Without implementing Public: When a class does not implement Public, all of its fields are private by default. That's why we have to explicitly write that the name and count properties...
