introduction to object oriented programming java

Why is object oriented programming better than procedural programming?
Object-oriented programming has several advantages over procedural programming: OOP helps to keep the Java code DRY "Don't Repeat Yourself", and makes the code easier to maintain, modify and debug Tip: The "Don't Repeat Yourself" (DRY) principle is about reducing the repetition of code.
What are the 4 principles of object oriented programming?
There are the four main principles of the Object-Oriented Programming paradigm. These principles are also known as the pillars of Object-Oriented Programming. The four main principles of Object-Oriented Programming are: Encapsulation (I will also touch briefly on Information Hiding) Encapsulation is when you wrap up your data under a single unit.
What is object oriented programming in Java?
Object-oriented programming is a common style of programming where you design your code to function like objects in the real world. In Java, understanding the basics of object-oriented programming is especially important because every piece of Java code that you write interacts with objects and classes.

What Is Object-Oriented Programming?

Object-oriented programming (OOP) is a fundamental programming paradigm based on the concept of “objects”. These objects can contain data in the form of fields (often known as attributes or properties) and code in the form of procedures (often known as methods). The core concept of the object-oriented approach is to break complex problems into smal

What Is Java?

Java is a general-purpose, class-based, object-oriented programming language, which works on different operating systems such as Windows, Mac, and Linux. You can use Java to develop: 1. Desktop applications 2. Web applications 3. Mobile applications (especially Android apps) 4. Web and application servers 5. Big data processing 6. Embedded systems

What Is A Class in Java?

A class is defined as a collection of objects. You can also think of a class as a blueprint from which you can create an individual object. To create a class, we use the keyword class. freecodecamp.org

What Is An Object in Java?

An object is an entity in the real world that can be distinctly identified. Objects have states and behaviors. In other words, they consist of methods and properties to make a particular type of data useful. An object consists of: 1. A unique identity:Each object has a unique identity, even if the state is identical to that of another object. 2. St

What Is The Java Virtual Machine (JVM)?

The Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs. The JVM has two primary functions, which are: 1. To allow Java programs to run on any device or operating system (this is also known as the "Write once, run anywhere" principle). 2. And, to manage and optimize program memory. freecodecamp.org

How Access Modifiers Work in Java

In Java, access modifiers are keywords that set the accessibility of classes, methods, and other members. These keywords determine whether a field or method in a class can be used or invoked by another method in another class or sub-class. Access modifiers may also be used to restrict access. In Java, we have four types of access modifiers, which a

How Methods Work in Java

A method is a block of code that performs a specific task. In Java, we use the term method, but in some other programming languages such as C++, the same method is commonly known as a function. In Java, there are two types of methods: 1. User-defined Methods: These are methods that we can create based on our requirements. 2. Standard Library Method

Key Principles of Object-Oriented Programming.

There are the four main principles of the Object-Oriented Programming paradigm. These principles are also known as the pillars of Object-Oriented Programming. The four main principles of Object-Oriented Programming are: 1. Encapsulation (I will also touch briefly on Information Hiding) 2. Inheritance 3. Abstraction 4. Polymorphism freecodecamp.org

Interfaces in Java

An interface is a collection of abstract methods. In other words, an interface is a completely "abstract class" used to group related methods with empty bodies. An interface specifies what a class can do but not how it can do it. Example: Output: freecodecamp.org

Conclusion

We have looked at some of the main object-oriented programming concepts in this article. Having a good understanding of these concepts is essential if you want to use them well and write good code. I hope this article was helpful. My name is Patrick Cyubahiro, I am a software & web developer, UI/UX designer, technical writer, and Community Builder
