Introduction
Java is an advanced, object-oriented programming language. It is a popular programming language among other OOPs languages because it is robust, secure, multithreaded, and platform-independent. In addition to being widely employed in the development of software, web, and mobile applications, it is also utilized in big data analytics and server-side technology. It is used for a variety of purposes by many Java fans. A wide range of applications, such as Android apps, games, desktop programs, network applications, and many more, can be built using Java. The primary subjects of this article will be Java's benefits and characteristics.
This blog showcases the major features of the Java programming language. However, before moving to that let us first learn why Java is such a widely used language.
What makes Java so Recognized by the Developers?
The platform independence of Java is the main factor. Because of the Java Virtual Machine, programmers may create software that is platform-independent, meaning that it can run on any platform or operating system, no matter what the underlying configuration. In other words, we can argue that Java complies with the WORA principle, which stands for Write Once Run Anywhere.

Java also offers the ability to construct several threads inside a single process that operate independently and concurrently. In addition to them, Java's performance is outstanding. It employs a JIT (Just in Time Compiler) that can only compile the method being called, not the entire program. Because of this, the development process is much more swift and effective.
The fact that the message 3 Billion Devices Run Java appears while Java is being installed confirms how widely used the Java programming language is. Java offers an extensive and complex collection of APIs to aid developers in the creation of apps. Java enables us to create a wide variety of programs, each serving a unique function. Java technology can be used to create applications such as mobile applications, Desktop GUI Applications, Web-based Applications, and Technology Applications for Big Data. Gain knowledge on how to create applications using Java by enrolling in an online java program.
There is a tonne of benefits to utilizing Java as a programming language, as well as a long number of arguments in favor of Java's superiority to other languages.

The Major Features of Java Programming Language
There are numerous features of Java that make it stand out from the other programming languages. Here are some of them:-
Java is a Simple Language
As a result of its lack of complications found in earlier programming languages, Java is a straightforward and simple programming language. Because it must operate on electronic devices with limited memory and resources, minimalism was really a design goal for the Javasoft team. The grammar of Java is identical to that in C and C++, so programmers who are transitioning to Java won't encounter any difficulties. Second, Java no longer uses pointers at all, which makes programming more difficult and exposes pointers to security risks.

Object-Oriented Nature
Another major feature of java programming language is its object-oriented nature. As an object-oriented programming language, Java allows for the creation of classes and objects for everything that is written. The definition of an object is simply a thing in the real world that may stand in for any individual, location, or item while still being unique. There is a state and behavior connected to every object in our immediate vicinity. For instance, a real-world object like a lunchbox has qualities like color, design, capacity, etc. These attributes are represented by variables. The actions that are connected with mobile devices, such as calling, messaging, photographing, etc., are represented by Java methods.
A class is a collective term for a group of objects that share the same state and behavior. For example, companies such as Tupperware, Milton, etc. fall under the category of lunchboxes. The following are the key ideas in any object-oriented programming language:
- Object and Class Encapsulation
- Transmission of Abstraction
- Polymorphism
Java is Platform Independent
Java enables programmers to create their code on any computer with any configuration and execute it on any other computer with a different configuration.
The bytecode produced by the compilation of Java source code is platform-independent. In actuality, the only program that can interpret this bytecode is the Java Virtual Machine that is installed on our machine. Each operating system has a unique JVM that can read bytecode and translate it into a language that a machine can understand. Currently, programmers only create one copy of a program and compile it. Find out more about Java's platform independent feature by taking up a java certification course.
Java is a Portable Language
Java is portable thanks to its platform independence and WORA (Write Once, Run Anywhere) principle. Developers may now get the same outcome on any system by writing only one line of code using the Java programming language. Bytecode and JVM are the causes of this. If you created any Java code, it would first be translated into a form that the JVM alone could understand—equivalent bytecode. For various platforms, we offer various JVM versions. Each of the three operating systems—Windows, Linux, and macOS—has its own version of the JVM. The JVM of any machine that receives your bytecode will convert it into the appropriate machine code.
Java is Secure
Each application has security as a top priority. Due to the fact that all devices are currently connected to one another over the internet, hacking is now a possibility. Java offers programmers security features. Java allows for the handling or minimization of security issues like malware threats, manipulation, eavesdropping, and impersonation. Your data is protected from internet eavesdropping and manipulation with encryption and decryption technologies. Java may be used to generate digital signatures. A virus is a program that can damage our system and is typically propagated through. exe files, image files, and video files, however, text files cannot be shared. It's a good thing that Java bytecode is also a text file (yep, a class file is a text file that is not readable by humans).

Conclusion
We have covered the design goal of Java in this article, namely that it be created as a system-independent language that adheres to the WORA (Write Once Run Anywhere) philosophy. Additionally, we studied Java's most advantageous traits, which set it apart from other programming languages in terms of popularity. You have undoubtedly learned something about the major features of the Java programming language at this point.
