Introduction to Object Oriented Programming in Java

Image
  Introduction to Object Oriented Programming and Java Introduction Object Oriented Programming (OOP) is a modern programming approach in which a program is designed using objects and classes . Java is a popular object-oriented programming language widely used in schools, colleges, and the software industry. This chapter helps students understand the basic concepts of OOP and Java , which form the foundation of advanced programming. 1. Principles of Object Oriented Programming Object Oriented Programming is based on four main principles : Abstraction Encapsulation Inheritance Polymorphism Procedure Oriented Programming vs Object Oriented Programming Procedure Oriented Programming      Object Oriented Programming Program is divided into functions Program is divided into objects Data is not well protected Data is well protected Less secure More secure Example: C language Example: Java, C++ Reusability is less Reusability is high 1. Abstractio...

Object Modelling – Entities and Their Behaviour in Java

Image
  Introduction to Object Modelling in Java      Java is an Object-Oriented Programming (OOP) language. In OOP, programs are designed by modelling real-world entities as objects . 👉 Object Modelling means representing real-life things inside a program using: Their properties (data) Their behaviour (actions) Components of Object Modelling Every object consists of three main components : 1. State (Properties / Attributes) State represents the data stored in an object . Examples: Student → Name, Roll Number Car → Color, Speed In Java → Variables int roll ; String name ; 2. Behaviour (Actions / Functions) Behaviour represents what the object can do . Examples: Student → Study, Write Exam Car → Start, Stop In Java → Methods void study () { System . out . println ( "Student is studying" ); } 3. Identity (Unique Name) Each object has a unique identity. Example: Student s1 ; Student s2 ; Here: s1 and s2 are different...
