More about methods

We might want two instances of Person to be able to procreate. We can implement this by writing methods. Instance methods are actions that an object does to itself; static methods are actions the type does.

Which you choose depends on what makes the most sense for the action.

Good Practice: Having both static and instance methods to perform similar actions often makes sense. For example, string has both a Compare static method and a CompareTo instance method. This puts the choice of how to use the functionality in the hands of the programmers using your type, giving them more flexibility.

Implementing functionality using methods

Let's start by implementing some functionality by using both static and instance methods:

1. Add one instance method and one static method to the Person class that will allow two Person objects to procreate, as shown in the following code:

   // static method to "multiply"
   public static...
