Calling Constructors

• Remember, a constructor is a method that initializes an object when it is created and the name of the method is the same as the class that it belongs to.

• You can call a constructor from inside of another one by using this as a method name:

      this(arg1, arg2, ...);

• When you create a constructor in a subclass, you will usually want to call the constructor in the superclass so that any inherited instance variables are initialized properly.

• Use the keyword super:

      super(arg1, arg2, ...);

• This must be the first statement in your method.

• If you don't explicitly use super to call one of the superclass's constructors, it will automatically call super() for you.
