Class - 10 things to know with detail

• What is a class?
• A class is a blueprint for creating objects in object-oriented programming. It defines the properties and behaviors that an object will have.
• How to define a class?
• In most programming languages, a class is defined using the class keyword followed by the class name and a code block containing the properties and methods of the class.
• What are properties in a class?
• Properties are the characteristics or data that an object of a class can have. They are defined within a class and hold values that describe the state of the object.
• What are methods in a class?
• Methods are functions defined within a class that can perform actions or operations on the object's properties. They define the behavior of the object.
• What is object instantiation?
• Object instantiation is the process of creating an instance of a class. When an object is instantiated, memory is allocated for the object, and the object's properties are initialized.
• How to create an object from a class?
• To create an object from a class, you use the new keyword followed by the class name and any arguments required by the class's constructor.
• What is inheritance in classes?
• Inheritance is a feature of object-oriented programming that allows a class to inherit properties and methods from another class. This promotes code reusability and helps create a hierarchy of classes.
• What is encapsulation in classes?
• Encapsulation is the concept of bundling data (properties) and methods that operate on the data (methods) within a class. It helps to hide the internal implementation details of a class and only expose the necessary interfaces.
• What is polymorphism in classes?
• Polymorphism is the ability of an object to take on different forms. In object-oriented programming, polymorphism allows objects of different classes to be treated as objects of a common superclass.
• How are classes used in programming?
• Classes are used to model real-world entities, abstract concepts, or data structures in programming. They help organize code, improve code readability, promote code reusability, and facilitate object-oriented design principles.
