and Principles of OOP Design (SOLID)

Pillers of OOP concept

2. Encapsulation
3. Inheritance
4. Polymorphism

Principles of OOP Design

2. Open-Closed Principle (OCP)
3. Liskov Substitution Principle (LSP)
4. Interface Segregation Principle (ISP)
5. Dependency Inversion Principle (DIP)

                                    public class Main {

    public static void main(String[] args) {
       /*
       Creating objects
        */
       Cat thor = new Cat();
       Cat rambo = new Cat();

       /*
       Defining Thor cat
        */
       thor.name = "Thor";
       thor.age = 3;
       thor.breed = "Russian Blue";
       thor.color = "Brown";

       thor.sleep();

       /*
       Defining Rambo cat
        */
       rambo.name = "Rambo";
       rambo.age = 4;
       rambo.breed = "Maine Coon";
       rambo.color = "Brown";

       rambo.play();
    }

}
