/**
 * Example: Generic Method with upper bound
 * The type parameter section specifies that T extends Comparable< T >only objects of classes that implement interface Comparable< T > can be used with this method.
 * In this case, Comparable is known as the upper bound of the type parameter.
 * By default, Object is the upper bound.
