Polymorphism: Why is it needed especially from an OOP standpoint? What is the essential concept when you cast objects regarding Polymorphism/Inheritance? Generics: Explain Generic Programming. Why is generics important as a data type regarding objects? Polymorphism and Objects: Explain an array of polymorphic objects in a single/double dimensional array. How do you access this? How do you process this? When would you use this? Also, when the new topic/chapter is posted regarding File/IO: Write a few lines of code that allows you to save/retrieve this data from a file using the appropriate class/methods. Do this in two ways: StreamFile I/O and URL access. You can also illustrate this in your code via text (.txt) and binary (.dat) data access. Also, write a few more additional lines of code illustrating StreamFile I/O access for .txt and .bin files. PROGRAMMING LANGUAGE - JAVA
