![]() Let's implement our own generic class Locker that can hold one object of any type. The type parameters are usually defined with a single character. Dictionary meaning of reflection: The throwing back by a body or surface of light, heat, or sound without absorbing it. ![]() Each of them is placed between the 'smaller than' and 'greater than' signs, like this: public class Class. Using generics is done in the following manner: after the name of the class, follow it with a chosen number of type parameters. The choice is based on the generic type parameter in the definition of the classes, which makes it possible to choose the type(s) at the moment of the object's creation. Generics relates to how classes that store objects can store objects of a freely chosen type. How on Earth can you implement a class that can contain objects of a given type? For example, a list that stores strings has been defined as ArrayList, and a hash map that stores keys and values as Strings has been defined as HashMap. Since we began using lists, we have given data structures the type of the values that we want them to store. A method to return an array of Parameter objects would be defined in, which is a common superclass of Method and Constructor.
