This week we learned about generic programming, which reduces the amount of code through generic classes. When calling a generic class, you can do a series of actions by changing the type variable. A generic class can have more than one type variable, and a type variable specifies the return type of the method and the type of the local variable. A generic method can be defined in a normal class or in a generic class, and if the class that implements the generic interface is a normal class, then
