Calling Constructors

• A constructor is a method that initializes an object when it is created.
  
  
• The name of the method is the same as the class that it belongs to and it does not have a return type.
  

• You get the default constructor by default unless you write another constructor.
  
  
• 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.
  
  
• While you are learning, you can include the explicit call to super().
