Program Plan Intro
Generic Class:
- It is a class in which the class name is followed by the type parameter section.
- In generic class, one or more type arguments are separated by commas.
- The programmers are enabled to specify a single class declaration with a set of related type.

Java programming - Using your knowledge in oop, inheritance, generics, create a generic class from non-generic class then create objects of type (int, sting, boolean, mixed). Write all necessary classes, functions that will return an object of each inherited data type
Why do we use generic methods?
Generic methods allows for code reuse (for different data types)
Generic methods allows for the Object class (the generic data type) to be used
Generic methods allow for handling abstract class (of which there can be no
instantiations)
The compiler will automatically generate test cases based on the appropriate
data types
please help me understand this code in java (using generic method). More specifically why was item1,item2, item3 parameter names never used again and what is the purpose of this line of code:
TheType tripleMin(TheType item1, TheType item2, TheType item3) {
