Java is well-known among developers for its dependability, making it a versatile and safe programming language. It is known as one of the earliest object-oriented languages. Java’s robust features support various applications—from Android and desktop development to enterprise solutions and cloud computing. It is also recognized as one of the top languages developers want to learn. Java’s applications in tech are both vast and valuable. In this article, we will look into Java’s fundamental features, and its application in various domains, and provide examples to make things easier for you to understand.
Features of Java:
Platform Independent
It has a core philosophy of Write Once, Run Anywhere. Java is compiled into a platform-independent form – Byte Code.
Byte-Code can be executed on any computer that has the Java Virtual Machine (JVM) installed. Object-Oriented
It started as a language to overcome the limitations of C++.
It is a purely object-oriented programming language. The object-oriented approach makes Java secure, reliable, and scalable.
What Is Object-Oriented Programming?
Object-oriented programming is a paradigm of programming. Functional programming, procedural programming, and task-oriented programming are the other paradigms of programming that are generally acknowledged. Object-oriented programming is based on objects which contain data and methods (functions). It encourages reusability and modularity. Object-oriented programming’s most significant characteristics are: Abstraction
Inheritance
Encapsulation
Polymorphism
Secure
Language before Java such as C++ had a major drawback of security. It has features to ensure enterprise-level security in its applications.
The features such as runtime checking, no use of pointers, exception handling, access control and type-checking, are responsible to provide such high-security standards to Java.
Simple
It is simple syntax and great readability due to the modular nature of code. It is easy for a beginner to start off and understand the key principles of the language.
Robust
It is a robust programming language. It is termed robust or strong for its strong features such as efficient memory management, automatic garbage collection, exception handling, and type checking.
Because of these features, it is the preferred programming language for building complex enterprise applications with ease and dependability. Architecture Neutral
It has solved the binary-distribution problem. The code is transformed into a “binary code format” that does not depend on hardware architectures, interfaces for operating systems, or window systems. Its run-time platforms are used for different hardware and software environments.
Any Java code written on any system configuration can run on any different system without the need to change the code. The format of “Byte code format is system independent making it architecture-neutral.
Multi-threaded
It gives you the ability to run multiple processes together to maximize the utilization of the CPU.
These threads run simultaneously. It is also known as concurrency in Java. With its multithreading feature, you can create interactive applications as a developer. High Performance
It has Just-In-time compilers that make it faster and enable high performance.

Other Features And Functionality of Java :
There are various other aspects of it that make it a desirable choice to learn and do development:
Community Support – It has matured over time and has a constant large developer community. It is always great to have community support to resolve issues and grow together as a community.
It is owned by Oracle and has huge support from Google and IBM.
There are some of the best IDEs for development in it. It simplifies software development, testing, and debugging. The most popular ones are Eclipse and Netbeans.
It has a huge open-source library to experiment with and use in your projects.
It is the foundation for Rapid Application Development (RAD) frameworks. Some of the most popular frameworks are Spring, Vaadin, Hibernate, and JSF (JavaServer Faces).
Why should I learn Java?
Java is a versatile language. You can explore diverse developments with this one language. It has a market and makes your skill employable.
If you are interested to know the salary offered of Java developer then according to Indeed.com, The average salary of a Java developer in the USA is $103476.
It is quite higher than in many competitive languages. You can do development in the following areas:
Android Development
Android development is one of the recent excitement. It is a growing field and most of the companies are making new development in this field.
Flutterby Google is gaining popularity nowadays. React-native by Facebook is also a popular choice among Android developers. Android programming is based on the Java programming language.
So it is a prerequisite to learn java to get started with android development.
Kotlin is the programming language of choice for Android developers. Many organizations are shifting their codebase to Kotlin.

Web Application Development
Java is also popular to build secure, robust, and scalable web applications.Java servlets, JSPs, and web containers are the technologies popular for web development.
