Java for Beginners

Core Programming & OOP Principles

Description

Java is one of the most widely used programming languages for developing robust and scalable applications. In this beginner-friendly course, you will learn the core concepts of Java programming, including variables, data types, control flow, and methods. You will also dive into object-oriented programming (OOP) principles like classes, objects, inheritance, polymorphism, and encapsulation. This course will provide a strong foundation in Java, enabling you to write efficient, maintainable code. By the end of the course, you’ll be equipped to build basic Java applications and understand the key principles that power more complex software systems.

Course Content

Introduction to Java Programming

Overview of Java, its history, and why it’s widely used in software development.

Setting Up the Java Development Environment

Install Java Development Kit (JDK), set up an IDE (IntelliJ IDEA or Eclipse), and create your first Java program.

Variables, Data Types, and Operators

Learn how to declare variables, use basic data types, and perform mathematical operations with operators.

Control Flow: Conditionals and Loops

Use if, else, switch, and loop constructs (for, while, do-while) to control the flow of your program.

Methods in Java

Learn how to define and call methods, pass parameters, and return values in Java programs.

Arrays in Java

Work with arrays to store and manipulate collections of data.

Introduction to Object-Oriented Programming (OOP)

Learn the four pillars of OOP: classes, objects, inheritance, and polymorphism.

Creating Classes and Objects

Understand how to create classes and instantiate objects, and how to use constructors and methods.

Inheritance and Polymorphism

Learn how to extend classes to reuse code (inheritance) and use polymorphism to improve flexibility and scalability.

Encapsulation and Abstraction

Understand how to hide implementation details and expose only the necessary parts of your classes (encapsulation), and how abstraction helps manage complexity.

Requirements

No prior programming experience required.
A computer with internet access.
Java Development Kit (JDK) installed on your system (instructions provided).
IDE: IntelliJ IDEA, Eclipse, or NetBeans (recommended).
Basic understanding of computer programming concepts is helpful but not required.
