This week, we learned about generic programming and learned about the benefits of generic methods, which are that generic classes improve the type safety of Java programs, eliminate forced type conversions, and increase the reuse rate of code.A generic parameter type can use the extends statement to define the upper bounds of a generic variable, and the upper bound declared by the extends keyword can be either a class or an interface. Classes handled by T in the public numbergenericArrays are co
