According to an estimation by the United States Bureau of Labor Statistics, 1,469,000 software developers are there in the country, and 35% of these web developers use java programming as one of the popular programming languages. So, it's the better choice to pursue your career as a Java developer in the USA. Are you looking for a complete roadmap to master java skills and want to become a successful java developer? If yes, look no further. 

In this article, we'll unveil the concept of Java programming, Object Oriented Programming (OOP), the responsibilities of java developers, how much java developers earn, and the steps to become a java developer. Let's begin with what is java programming: 

What is Java?

Java is a popular programming language used to develop mobile and web applications. The early concept of java language was given by 'The Green Team' in the early 1990s. James Gosling, a team member of this team, contributed a lot to the progress of the java language and earned the title of "Father of Java." Gosling was a senior software developer at Sun Microsystems (today known as Oracle) when he introduced Java programming language. After the release of Java language, many programming languages were introduced, such as Python, PHP, and JavaScript, but Java has maintained its status as the most popular programming language. The reason for this hype is the simple, portable, secure, multithreading, and dynamic nature of Java language. 

JAVA

Currently, there are four editions of Java that you need to learn to become a competent Java developer. Let's unveil the broader view of these editions: 

Java Card

Java developers use this java edition to support small processing devices such as ATMs and SIM cards.  

Java Standard Edition

Java developers use this standard edition to develop software for desktops and servers.

Java Micro Edition

A java developer uses java micro edition to develop mobile programs (Android and iOS). 

Java Platform Enterprise Edition

 A java developer uses this java edition to develop enterprise-level programs such as CRM. After going through the concept of java programming, you need to understand the concept of Object Oriented Programming to become a java developer.

What is Object Oriented Programming?

Java organizes its objects using Object-Oriented Programming (OOP) language. An object in OOP is an entity with a unique identity and properties. As a java developer, you need to understand the principles of OOP. Let's discover: 

Encapsulation

 Encapsulation encloses data and functions into a single unit in a private mode. This mechanism helps java developers to secure the data and methods and restricts their access to public functions. 

Abstraction

Abstraction in OOP is used to disclose the necessary details while hiding the other data. This concept helps java developers to share the required data that helps in software development. 

 Inheritance

Since OOP works with real-world entities, inheritance deals with building logical relationships between these objects/entities. Inheritance allows a java programmer to reuse the code by sharing the common logic of the child and parent classes. 

Polymorphism

Polymorphism in OOP allows a java programmer to use the different child classes with the same interface as the parent class. This approach helps the java programmer to reuse the code when developing similar software tools. 

Apart from these concepts, you need to understand the SOLID principle of OOP to become a java developer with high java developer skills. 

  • S: S stands for Single Responsibility Principle, which implies that one class should solve only one particular problem. 
  • O: O in SOLID principles refer to the Open-Closed Principle that says that a java developer should extend the objects (classes, methods) instead of adding new parameters. 
  • L: L refers to the Liskov Substitution Principle that says that a java developer should replace superclasses with subclasses smoothly while keeping the code logic right. 
  • I: I indicate the Interface Segregation Principle that implies that a java programmer should develop different interfaces for different clients. 
  • D: D indicates the Dependency Inversion Principle that says that a java developer should not make the higher-level modules of java coding lower-level modules.

So, the SOLID principle of OOP helps java developers to learn java developer skills for java development. 

What does a Java developer do?

The role of a Java developer highly depends on the project's nature and seniority level. But most java developers perform similar tasks in a software development life cycle (SDLC). Now, let's unveil the responsibilities of a java developer in software development based on his/her experience:
