	A consturctor is a special method that is used to instantiate an object, 
	it does not have a return rype. 
	A constructor is always called when an object is created, it's inovked with
	the "new" keyword 

	(implicit) Default constructor: 
	The JVM will always provide a constructor if none have been provided. It's 
	provided udring compile time. 

	Other than creating it in memory, it does nothing else. Effectively it is 
	a no args constructor with no body. 

	No-args construcotr: 
	It's developer created and allows us to do things
