Why Java isn't purely object-oriented?

Introduction

In recent years, Object Oriented Programming (OOP) has become very popular. This is because OOP has many advantages over traditional procedural programming. OOP makes code more reusable, more maintainable, and more understandable.

However, not all programming languages are pure OOP languages. In order to be a pure OOP language, a language must satisfy certain qualities.

In this article, we will discuss the qualities that a programming language must have in order to be considered a pure OOP language. Also, we'll discuss why Java isn't a pure Object-Oriented language.

Since its inception, Java has been one of the most popular programming languages in the world. Java is known for being a versatile and powerful language that can be used for a variety of purposes. While Java is often thought of as a purely object-oriented language, this is not the case. In fact, Java is a hybrid language that combines both object-oriented and procedural programming paradigms.

Why isn't Java purely object-oriented?

There are a few reasons why Java isn't purely object-oriented. First, Java was designed to be backwards compatible with C++. As a result, Java inherited many of C++'s procedural features. Second, Java's primitive data types (int, char, etc.) are not objects. This makes it difficult to create truly object-oriented programs in Java.

Despite these shortcomings, Java is still a very popular language. This is because Java offers a good balance between object-oriented and procedural paradigms. Java programs can be written in a purely object-oriented style, or they can make use of procedural features when needed. This makes Java a versatile language that can be used for a wide variety of programming tasks.

Qualities Of A Pure OOP Language

These are some qualities to be satisfied for a programming language to be purely Object Oriented.

• Support For Classes And Objects:

  The most important quality of a pure OOP language is that it must support the concept of classes and objects. A class is a template for creating objects. An object is an instance of a class. For example, in the Java programming language, the class String is a template for creating String objects. The class String has data members (variables) and member functions (methods).

• Support For Inheritance

  Another important quality of a pure OOP language is that it must support inheritance. Inheritance is a mechanism for creating new classes from existing classes.

With inheritance, a new class can inherit the data members and member functions of an existing class. This makes code more reusable.

• Support For Polymorphism

  Polymorphism is another important quality of a pure OOP language. Polymorphism is the ability of an object to take on different forms.

There are two types of polymorphism: static polymorphism and dynamic polymorphism. Static polymorphism is also known as early binding. With static polymorphism, the type of an object is determined at compile time.

Dynamic polymorphism is also known as late binding. With dynamic polymorphism, the type of an object is determined at run time.

• Support For Encapsulation

  Encapsulation is another important quality of a pure OOP language. Encapsulation is the process of hiding the details of an object from the outside world. Encapsulation is achieved by using access modifiers. The three access modifiers are public, private, and protected. Public members are accessible to the outside world. Private members are only accessible to members of the same class. Protected members are accessible to the members of the same class and the members of the child classes.

• Support For Abstract Data Types

  Abstract data types are another important quality of a pure OOP language. Abstract data types are data types that are not tied to any particular implementation. For example, the Java programming language has an abstract data type called the String. The String is not tied to any particular implementation. It can be implemented as an array of characters, a linked list of characters, or any other data structure.

Conclusion

A pure OOP language is a programming language that satisfies the following qualities: support for classes and objects, support for inheritance, support for polymorphism, support for encapsulation, and support for abstract data types.
