Java is one of the best coding languages for software development and game development among various programming languages. Due to its user-friendly and flexibility, it is widely used by developers. Moreover, it is popular because of its platform independency. The system which has configured java Runtime Environment (JRE) programmer can run it on multiple devices. Moreover, there are various benefits to utilizing the Java programming language as it is a highly scalable, flexible, and object-oriented programming language.
So, to learn more about the Java programming language, you can join Java Training In Chennai to acquire a comprehensive understanding of Arithmetic Operators, Logical Operators, Object-Oriented Programming Basics, etc.
Now, we shall discuss oops features in Java, why Java is a demanding career, what are oops concepts in Java, and basic java concepts.
Why is Java a demanding career?
Java is still a demanding programming language, and there are approximately 10 million Java developers worldwide, and this number is growing daily. So, who have intended to begin their career as java developer has wider opportunities in IT sectors globally.
If you want to start a career in software development, one of the best programming languages to learn is Java because it is a featured coding language. According to the survey, over 250 million television stations and 3.4 million mobile app applications use the Java coding language. Furthermore, software development is predicted to grow by more than 25%, according to more than 1 million consumers.
Many IT organizations like Accenture, Capgemini, MindTree, Zoho, Cognizant, HCL, Tech Mahindra, Wipro, Infosys, Oracle, Paypal, Sutherland, etc., hire an individual who has excellency in Java coding. Moreover, many social media platforms like Instagram, Pinterest, Google, Spotify, Netflix, etc., utilize it because of its flexibility.
Many top IT-based organizations offer multiple job roles like Java developer, Java Web Developer, Solution Architect - Java/J2EE, Application Developer, Database Administrator, etc.
Moreover, freshers who have completed their Java certification course would have access to explore their career opportunities. Almost every IT organization recruits freshers with excellent programming skills.
So, to have a comprehensive understanding, you can take up the Java Online Course to have in-depth knowledge of java concepts, strings, Java EE, etc. Freshers who have completed this course would be paid around ₹ 2 to 3 LPA.
Now, we shall look atoops features in Java and the concept of OOPS in Java in detail.
Definition of OOP Concepts in Java
An object-Oriented Programming System is a programming concept based on abstraction, encapsulation, inheritance, polymorphism, and many others. It enables users to construct their objects and ways to deal with them. The fundamental idea behind OOPs is to create objects, recycle them throughout the program, and modify them to achieve desired outcomes.
Object-Oriented Programming is a well-known and commonly utilized concept in current programming languages such as Java.
Now, we shall discuss the Java oops concept, java core concepts, and the concept of OOPs in Java.
OOPs features in Java:
-
Class
-
Object
-
Inheritance
-
Polymorphism
-
Abstraction
-
Encapsulation
-
Association
-
Aggregation
-
Composition
Class
Class is the fundamental concept of oops. The cluster of objects is called class. A class can be regarded as a blueprint from which a particular object can be created, and it does not require any room.
Object
The object can be physical or logical. The object can be anything like a chair, car, pen, etc. The instance of the class can be defined as an object. An entity holds an address and occupies memory space. Objects can communicate even if they are unaware of one other's information or code.
Inheritance
Inheritance is a feature of Java's Object-Oriented Programming that allows programmers to build new classes that inherit some of the same traits as existing classes. Using inheritance enables us to develop on earlier work without starting from scratch.
Polymorphism
Polymorphism occurs when a single task is completed in multiple ways.
To create polymorphism in Java, we employ method overloading and method overriding.
Abstraction
It is one of the oops characteristics. It is the process of developing new information that is fitted for a particular application. Now, we shall look at the meaning of the concepts with examples:
For example, while we drive a car, we won't be concerned about its engineering works; instead, we look at the gear, accelerator, steering wheels, clutch, etc.
Encapsulation
It is one of the best java core concepts in which all data and code are wrapped in a single unit. A class's components are always protected from other classes. Encapsulation, in other words, hides the data and code within the class.
For example, students are unable to leave their school without attending class.
Association
It is the best concept of oops in Java, which has significant links between two objects. In this association concept, all objects have their lifecycle. Now, we shall discuss with an example:
India has one prime minister, and the prime minister has many ministers. Still, ministers have only one prime minister, and ministers have many sub-department under them. So, the relationship can not be defined in particular, and it is un and bi-directional.
Aggregation
Aggregation is a method of attaining Association. Aggregation refers to a relationship in which one object's state includes other items. It symbolizes an unstable connection between objects.
Composition
Association can also be established through composition. The composition denotes a connection in which one thing includes other objects as part of its state. So, there is a strong relationship between the parent object and the child object.
To learn more about the Java core concepts, Java oops concept, and oops features in Java, you can join the Java course to have exposure to wider opportunities.
Now, we shall discuss the Advantage of OOPs over Procedure-oriented programming languages.
Advantage OOPs concepts in Java
-
OOPs makes quality and reliability, but an object-oriented programming language might be difficult to maintain as a project grows in size.
-
Data can be accessed from anywhere in a procedure-oriented programming language, but OOPs allow data encapsulation.
-
OOPs concepts in Java provide a clear and easy-to-understand modular approach for programming.
-
Objects produced in Object-Oriented Programs can be utilized in other applications. As a result, it saves a lot of money on development.
-
Large programs are hard to write, but if the development and implementation teams adhere to the OOPS principles, they will be able to create better-looking systems with fewer defects.
-
Because each item lives on its own, it improves software modularity.
Now, you would have understood the OOPs features in Java, the concept of OOPs in Java, and the advantages of OOPs concepts. So, individuals who have Java certification can explore their career opportunities globally; moreover, many top companies recruit individuals with excellent Java coding skills. So you can take up Java Training In Bangalore to have a comprehensive understanding of Java Basics, Program Structure of the Java constructors, Bitwise Operators, arrays, etc.
