Question

How does Generics and Parameterized classes promote reusability, give an example?

Answer 1

Introduction:

• Generic is a category that allows the user to define classes and methods with a local host. The basic idea behind using a generic is to allow the type (Integer, String, ... etc, and user-defined types) to be a composite of methods, classes, and forums.
• The main limitation of the clusters is the lack of functional testing of the type. This means that you can put anything in the collection because all classes of programming language extend from the base of the object.
• This drops the security of the genre and goes against the basic definition of C # as a secure language. In addition, using clusters includes a number of functionality in the form of transparent and precise installation of the type required to insert or retrieve items from a collection.

Generic category:

General in C # is its most powerful feature. Allows you to define secure data structures. This turns out to be amazingly powerful for working with high-level code because it helps to use algorithms for data processing without having to duplicate code of some kind.

Genetics are similar to templates in C ++ but are different in functionality and capacity. General introduces the concept of type parameters, due to the possibility of creating methods and classes that limit data type entries until the class or method is declared and entered by the client code. Parameter types are defined in standard class creation.

Benefits of Generics:

Uses for reuse: You can use one standard type definition for multiple purposes in the same code without any changes. For example, you can create a standard way to add two numbers. This method can be used to enter two numbers and two flats without code modification.

Security Type: Standard data types provide better type security, especially in the case of clusters. When using generics you need to define the type of objects to be passed to the collection. This helps the compiler to ensure that only those types of items specified in the description can be passed to the collection.

Functionality: Standard edition types provide better performance compared to standard program types because they reduce the need for box placement, non-boxing, and typing of variables or objects.

To make objects of a generic class, we use the following syntax.

// To create an object of generic class 
className <Type> obb = new className <Type>()

Type= Integer, String, etc
