Arrays of Objects
lWhen 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
