Java OOP Lecture 1 | Introduction to Java, Variables, Classes, Objects & Operators

Welcome to Lecture 1 of Object Oriented Programming (OOP) using Java! In this beginner-friendly session, we introduce Java programming and cover essential concepts needed to start building Java applications. In this lecture, you will learn what Java is, why it is widely used, and how to set up your development environment using JDK and Eclipse IDE. We also explore core programming concepts such as variables, classes, objects, access modifiers, and operators. ⏱️ Timestamps: 0:00 Introduction to Java Programming 0:46 What is Java & Why Java 4:59 Setting Up Java (JDK & Eclipse IDE) 7:32 How Java Works (JDK, JVM, JRE) 16:25 Java Variables (Instance, Local, Static) 20:27 Creating Java Project in Eclipse IDE 23:02 Variables Demo 28:46 Static Variables Demo 33:13 Classes and Objects in Java 40:22 Methods in Java 47:11 Constructors Demo 1:00:18 Access Modifiers (Private, Default, Protected, Public) 1:08:44 Access Modifiers Demo 1:19:14 Java Operators 📘 In this lecture, you will learn: - What Java programming is and its importance - How Java works (JDK, JVM, JRE) - How to install and set up Java development tools - Types of variables in Java - Classes, objects, methods, and constructors - Access modifiers in Java - Java operators and their usage This lecture is ideal for: ✔ Beginners learning Java programming ✔ Students studying Object Oriented Programming ✔ Anyone preparing for exams or coding interviews 💻 Follow along and practice the examples to strengthen your understanding. 🚀 Next Lecture: We will dive deeper into Object Oriented Programming concepts such as inheritance, encapsulation, polymorphism, and abstraction. 📌 This is part of a full Java OOP course—follow the playlist for the complete learning experience. 👍 Don’t forget to LIKE, COMMENT, and SUBSCRIBE for more programming lectures. #JavaProgramming #OOP #LearnJava #ProgrammingForBeginners #ObjectOrientedProgramming
