Java OOPs Concept: Class & Object Basics

📘 Day 1 OOPs Concept – Class & Object Welcome to Day 1 of my journey to level up from Manual Testing to Automation Testing 🚀 Today, we’re covering one of the core fundamentals of Java — Class and Object, which form the foundation of OOPs and test automation frameworks. 🔹 Understanding what a class is 🔹 How objects are created from a class 🔹 Why this concept is critical for Java-based automation Every automation journey starts with strong basics 💡 🔹 Class A class is a blueprint or template that defines the attributes (variables) and behaviors (methods) of an object. It is a logical entity A single class can have n number of objects It does not occupy memory until an object is created Example: Animal is a class Attributes: name, color, age Behaviors: eat(), sleep() 🔹 Object An object is an instance of a class. It is a real-world entity It occupies memory Multiple objects can be created from the same class 🧑💻 Simple Java Example class Animal { String name; int age; void eat() {     System.out.println("Animal is eating");   } } public class Main {   public static void main(String[] args) { // Creating an object of Animal class    Animal dog = new Animal(); dog.name = "Dog";     dog.age = 5;     dog.eat();   } } 📝 Explanation: 👉 Animal is the class 👉 dog is the object of the Animal class 👉 Using the object, we access variables and methods of the class Automation frameworks (like Page Object Model) are built using classes and objects. Each web page is represented as a class, and its elements and actions are defined using methods. #Java #OOPsConcept #ClassAndObject #ManualToAutomation #TestAutomation #LearningJourney
