Program Plan Intro

Generic Programming:

• Java generic classes and generic methods allow the programmers to specify, with a single class declaration, a set of related types and with a single method declaration, a set of related methods.
• Using the concept of generics, user can write a generic method sort for sorting objects array then call this method with String arrays, Integer arrays, Double arrays and more for sorting the elements of the array.

Generic Classes:

• The declaration of generic class looks like a non-generic class declaration except the type parameter section followed by the name of the class.
• The generic class can have more than one parameters separated by commas. This type of classes is called as parameterized types or parameterized classes because these classes accept one or more parameters.
