Arrays of Objects
	• When you create an array of objects – You are really creating an array of references – Which are automatically initialized to null – Java interprets a null as being a reference which isn’t pointing to an object – You must assign an object to each reference before you use it! – And, if you try to use a reference while it is still null, you will get a run-time error reported – Plus, Java provides for range checking – so that arrays cannot be accessed outside of range
