     As the name suggests, Object-Oriented Programming or OOPs refers to languages that use objects in programming, they use objects as a primary source to implement what is to happen in the code. Objects are seen by the viewer or user, performing tasks assigned by you. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc. in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.

     Let us discuss prerequisites by polishing concepts of method declaration and message passing. Starting off with the method declaration, it consists of six components: 

     private: Accessible only within...

     • public: Accessible in all classes in your application.
     • protected: Accessible within the package in which it is defined and in its subclass(es) (including subclasses declared outside the package).
     • private: Accessible only within the class in which it is defined.

     Assuming that you have a copy constructor in Model. You need y use simply Model constructor, which is possible with Gooko object, because Gomoku extends Model. Please check this example.

     Data Abstraction is the property by virtue of which only the essential details are displayed to the user. The trivial or non-essential units are not displayed to the user. Ex: A car is viewed as a car rather than its individual components.Data Abstraction may also be defined as the process of identifying only the required characteristics of an object, ignoring the irrelevant details. The properties and behaviors of an object differentiate it from other objects of similar type and also help in classifying/grouping the object. - -//abstract class abstract class GFG{   //abstract methods declaration   abstract void add();   abstract void mul();   abstract void div(); } -Pillar 2: Encapsulation - -//Encapsulation using private modifier    //Employee class contains private data called employee id and employee name class Employee {     private int empid;       private String ename; } -Pillar 3: Inheritance  - -//base class or parent class or super class class A{   //parent class methods   void method1(){}   void method2(){} }   //derived class or child class or base class class B extends A{  //Inherits parent class methods   //child class methods   void method3(){}   void method4(){} }-Pillar 4: public Gomoku ( Gomoku other ){ super(other); // this will initialize all Model properties // set other properties, that belong only to Gomoku }-

     By invokin super(object) you are refering to Model constructor, that accepts Model as an argument. Because Gomoku extends Model, you can use Gomoku object here.

     In your Model class you have a problem with property order. Line containing

     if (other.w <= 0 || other.h <=0) return;-

     Can break initializing of winningSequence list, so you can initalize it before the declared constructor.

     class Model{private List<?> winningSequence = new ArrazLis<>();- public Model ( Model other ) { // your constructor }} -

     or

     public Model ( Model other ) { this.winningSequence = new ArrayList<>(); // use this before if statement }-

     Let us discuss prerequisites by polishing concepts of method declaration and message passing. Starting off with the method declaration, it consists of six components: 

     • Access Modifier: Defines the access type of the method i.e. from where it can be accessed in your application. In Java, there are 4 types of access specifiers: 
     • public: Accessible in all classes in your application.
     • protected: Accessible within the package in which it is defined and in its subclass(es) (including subclasses declared outside the package).
     • private: Accessible only within the class in which it is defined.
     • default (declared/defined without using any modifier): Accessible within the same class and package within which its class is defined.

     Message Passing: Objects communicate with one another by sending and receiving information to each other. A message for an object is a request for execution of a procedure and therefore will invoke a function in the receiving object that generates the desired results. Message passing involves specifying the name of the object, the name of the function and the information to be sent.

     • Modifiers: A class can be public or have default access (Refer to this for details).
     • Class name: The class name should begin with the initial letter capitalized by convention.
     • Superclass (if any): The name of the class’s parent (superclass), if any, preceded by the keyword extends. A class can only extend (subclass) one parent.
     • Interfaces (if any): A comma-separated list of interfaces implemented by the class, if any, preceded by the keyword implements. A class can implement more than one interface.
     • Body: The class body is surrounded by braces, { }.
     • State: It is represented by the attributes of an object. It also reflects the properties of an object.
     • Behavior: It is represented by the methods of an object. It also reflects the response of an object to other objects.
     • Identity: It is a unique name given to an object that enables it to interact with other objects.
     • Method: A method is a collection of statements that perform some specific task and return the result to the caller. A method can perform some specific task without returning anything. Methods allow us to reuse the code without retyping it, which is why they are considered time savers. In Java, every method must be part of some class, which is different from languages like C, C++, and Python. 
     • Technically, in encapsulation, the variables or the data in a class is hidden from any other class and can be accessed only through any member function of the class in which they are declared.
     • In encapsulation, the data in a class is hidden from other classes, which is similar to what data-hiding does. So, the terms “encapsulation” and “data-hiding” are used interchangeably.
     • Encapsulation can be achieved by declaring all the variables in a class as private and writing public methods in the class to set and get the values of the variables.
     • Superclass: The class whose features are inherited is known as superclass (also known as base or parent class).
     • Subclass: The class that inherits the other class is known as subclass (also known as derived or extended or child class). The subclass can add its own fields and methods in addition to the superclass fields and methods.
     • Reusability: Inheritance supports the concept of “reusability”, i.e. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. By doing this, we are reusing the fields and methods of the existing class.
