OOP Simplified: Breaking Down the 4 Core Principles
- A constructor is a special method used to initialize an object when it is created in object-oriented programming.
- Inheritance is one of the key principles of object-oriented programming (OOP) which allows a class to inherit properties and methods from another class.
- Polymorphism enables the same entity (like a method or object) to behave differently in various scenarios.
- Method overloading takes place in the same class. It is determined during compile-time and its key feature is that it has different parameter lists.
- Method overriding is determined during run-time and happens between parent and child classes. Its key feature is that it has the same name and parameter list.
- There are multiple types of inheritance namely single inheritance, multilevel inheritance, and hierarchical inheritance.
- The 'this' keyword refers to the current object of the class and 'super' keyword is used to refer to the parent class in a child class.
- Inheritance allows you to reuse code instead of rewriting it and create a hierarchy between classes for better organization.
- Polymorphism enables the same interface to represent different behaviors depending on the context.
- Encapsulation and Abstraction are two more pillars of object-oriented programming and will be explained in detail in the next blog.
