Class And Object- Java Object Oriented Programming Lab Report
- 1. LAB REPORT CSE222: Object-OrientedProgramming Lab Topic: Class & Object Submitted To Shahriar Hossain Shanto (SHS) Designation Department of CSE, Daffodil International University Submitted By Student ID: 0242310005101263 Section: 64_K2 Student Name: Md Rakibul Hasan Date of Assignment Submission: 22nd November 2024 01
- 2. Experiment No: 01Mapping: CO1 and CO2 Experiment Name Class & Object Experiment Details: Class: A class in Java is a blueprint or template used to create objects. It defines properties (attributes) and behaviors (methods) that the objects of the class will have. Think of a class as a prototype for creating similar entities. Real-World Example Consider the concept of a Car. Every car shares attributes like brand, model, color, speed, and behaviors like start, stop, and accelerate. The class car would define these attributes and behaviors. Object: An object is an instance of a class. It represents a specific entity with a state (attributes) and behavior (methods). Objects are created using the new keyword in Java. Real-World Example A specific car, like a red Toyota Corolla, is an object of the class Car. This object will have specific values for its attributes, like color: red, brand: Toyota, and model: Corolla, and can perform behaviors like start, and accelerate. Code: //file Name : Main class Car { String brand; String model; String color; int speed; Car(String brand, String model, String color, int speed) { this.brand = brand; this.model = model; this.color = color; this.speed = speed; }

Toyota Corolla Current speed: 60 km/h Toyota Corolla has stopped. Tesla Model 3 is starting. Tesla Model 3Current speed: 80 km/h Tesla Model 3 has stopped. Desired Output? YES
