Anyone interested in Java software development will find it a good career choice to learn Java and become a Java developer.
This comprehensive guide will teach you everything you need to be a Java developer.
This guide will explain the skills required, job responsibilities, and the amount you can expect to be paid by your employer.
What is Java?
Before we can explore all, and if you are an enthusiast developer, it's essential to understand what Java is.
Developers use Java programming language to develop software and mobile applications.
In the early 1990s, Java was first conceptualized by a small group called "The Green Team." James Gosling was part of that team and later became the 'Father of Java' because of his contributions. Gosling was an engineer at Sun Microsystems, a subsidiary of Oracle today. He developed Java.
Java was initially designed to be:
- Simple
- Robust
- Portable
- Platform-independent
- Secure
- High Performance
- Multithreaded
- Architecture Neutral
- Interpreted
- Dynamic
Many modern programming languages, such as Scala, JavaScript, and PHP, have evolved from Java since its 1995 release.
One of the most popular programming languages is still Java.
There are currently four editions of Java:
-
Java Card is used to creating programs for devices with limited processing capabilities (such as SIM cards or ATM cards).
-
Java Standard Edition (Java SE) is used to create programs for servers and desktops.
-
Java Micro Edition creates programs for mobile devices (like iOS or Android).
-
Java Platform Enterprise Edition is used to create large-scale applications.
Who is a Java Developer, Exactly?
Java developers understand a website's client-side (front-end) and backend (server-side) sides.
Front-end developers design and implement the user interface (UI), while Java backend developers process user requests behind the scenes.
Backend services include logical processing, user validation, and database handling.
To be a full-stack Java developer, you must have a good understanding of both backend and front-end technologies.
You should also understand full-stack technology and the skills required for it.
Full-stack web development can also be proficient in coding languages, know databases, design and manage UI/UX, and have soft skills that will help them succeed.
What is Object-Oriented Programming (OPP)?
Java is an Object-Oriented Programming language (OOP), meaning it organizes design around objects instead of logic and functions.
An object is an entity that has a unique identity (sometimes called a label), characteristics (sometimes called state), and behavior.
OOP development is based on four key principles. These are:
-
Encapsulation refers to a condition in which an object's state, private and enclosed within its class (a template with similar properties that developers use to create objects), is achieved.
Public functions cannot access it.
-
Abstraction is when objects only reveal the essential details that you need to work with them.
This makes your program easier to create.
-
Inheritance is when objects are arranged into parent and child structures.
They share the same logic but do not have to be identical.
- Polymorphism allows you to use child classes as parent classes without changing the child class.
Many developers also use OOP to develop their projects. Robert Martin and Uncle Bob created these principles.
These are the SOLID principles:
-
S - The Single Responsibility Principle states that a class can only be responsible for one problem unless interconnected subsystems solve it.
-
O - The Open-Closed Principle states that entities should be extended but not modified (e.g., classes, modules, and functions).
-
L - The Liskov Substitution Principle states that superclasses should be replaced with subclasses without breaking your code.
-
I - The Interface Segregation Principle states that each client should have its interface.
-
D - The Dependency Inversion Principle states that higher-level modules should not support lower-level ones.
Java vs. JavaScript
Many newer Java developers need to learn about Java and JavaScript because they have similar names.
They are, however, distinct languages. Java is a compiler language. This means that Java is translated into machine code by the compilers. On the other hand, JavaScript is an interpreted scripting language that can be translated into machine code by its run.
Java and JavaScript have their uses. Java is used for client-side projects, while JavaScript is used for server-side development.
Java Developer vs. Software Engineer
Java developers are often confused with software engineers by new developers. However, these careers are also different.
Java developers are highly skilled professionals who (usually) work only with Java projects.
Software engineers have more skills to work with different programming languages and projects.
Many professionals switch between Java developers and software engineers because they have the same skills and roles. This allows them to be more varied, take on new challenges, or learn new skills.
You now have a good understanding of Java and are ready to explore custom java development as a career.
What is a Java Developer?
Java developer is also known as a Java engineer or Java developer. Specialist IT professionals works with Java developers.
