1.3 Object-Oriented Programming GEMTRIX

Implement setters and getters for the character type.

Represent properties, which are used to read, write, or compute a private field. These methods are usually public and allow you to access data

class Shirt

{

string material = "cotton";

}

First class keyword, then the class name, then a set of brackets, and within the brackets, and then create the variable

Delegate

An event to have an object signal an action's occurence.

Events go inside delegates, which provide a way to design and execute callbacks

Subscriber

A class that receives an event notification

EventHandler

Is a built-win delegate, which is a representative of a method with a particular parameter list and data type

Access Modifier : protected

If you want your data to be accessible by members of all derived classes

Access Modifier : private

Access Modifier : public

Access Modifier : derived

To instantiate a class

AreaRect areaRect1 = new AreaRect();

get

This method should replace the comment // access the private field. Is used to access a private field from within a public field

set

This method is used to assign a value to a private field

Public/Private Constructor

Is not needed when setting or returning a private variable

Generic Classes

Have operations that are not specific to a data type

Are used collections such as stacks, queues, hashed tables, and linked lists.

Have generic methods

Base Class

There is no set limit for how many classes can be derived from this class

Child Class

Cannot inherit from multiple parent classes

Derived Class

A class that inherits functionality from a base class

Abstract Class

Cannot be used to create objects.

Serves as a base for other classes to use its methods and have these classes have their own objects and methods

Interface

Contain abstract methods, meaning without a body

A class serves as a base for an interface

Can be implemented without using the override keyword
