A high-level, exclusively object-oriented programming language is Java. Among other OOP languages, it is well-liked because it is a multithreaded, robust, secure, and platform agnostic programming language. In addition to being widely employed in the development of software, web, and mobile applications, it is also utilised in big data analytics and server side technology. Let’s examine Java’s history before moving on to its features.
Why is Java so Popular?
The platform independence of Java is the primary justification. Because of the Java Virtual Machine, programmers who created their software on one platform can now execute it on any other platform or operating system, regardless of the underlying configuration. In other words, Java adheres to the WORA principle, which stands for Write Once Run Anywhere. In addition, Java offers protection against the threats of virus infection, tampering, impersonation, and eavesdropping. 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.

Why Use Java?
Java is simple for programmers to learn. Java is frequently chosen as the first programming language to learn. Furthermore, the industry continues to benefit from Java’s prominence. The majority of websites and apps in the government, healthcare, defence, and educational sectors continue to use Java technologies. Java is thus worthwhile to learn and use. If you choose a career in Java, you can follow a number of different career routes. Almost anything that Java can accomplish.
Top Java Features
Simple
Java is a straightforward programming language that is simple to learn since it lacks the intricacies found in earlier programming languages. Given that Javasoft must run on electronic devices with limited memory and resources, minimalism was actually a design goal. Java has the same grammar as C and C++, thus programmers transitioning to Java won’t encounter any syntax-related issues.
Object-Oriented
Due to the fact that Java is an object-oriented programming language, every code in Java is expressed in terms of classes and objects. What is an object, then? An object is nothing more than a physical thing that can stand in for any person, place, or thing while yet being unique. Every thing in our immediate vicinity has a specific state and behaviour.
Platform Independent
The developers at JavaSoft set out to create a language that would be compatible with every platform. Platform in this context refers to a class of operating system and hardware technology. Java gives programmers the flexibility to create their code on any machine with any configuration and run it on any other machine with a different configuration.
Portable
Java is portable thanks to the WORA (Write Once Run Anywhere) idea and platform independence feature. With the help of the Java programming language, developers may now produce the identical outcome on any machine with a single line of code. The JVM and bytecode are to blame for this. If you created any Java code, it would first be translated into corresponding bytecode that the JVM alone could understand. For various platforms, we have multiple JVM versions. Each of the three operating systems—Windows, Linux, and MacOS—has its own version of the JVM.
Robust
The Java programming language is resilient, so it can deal with an unexpected programme termination. This is due to two factors. First, it offers Exception Handling, a crucial and practical feature. In Java code, an exception won’t cause any harm, but in other low-level languages, the application will crash. Java’s memory management capabilities are another factor that makes it effective. Java offers a runtime garbage collector provided by JVM, in contrast to other low level languages, which gathers all the unused variables.
Secure
In the present world, security is the main issue for any apps. Hacking is now a possibility because all gadgets are currently connected to one another via the internet. For our Java application, we also require some sort of security. Java therefore provides security features to programmers. The threat of malware, manipulation, eavesdropping, and impersonation can all be managed or minimised with Java.
Interpreted
You’ve probably learned that programming languages either utilise a compiler or an interpreter, but the Java programming language uses both. When Java programmes are executed, the JVM interprets the bytecode files that were created during compilation. Additionally, JVM makes use of a JIT compiler (it increases the speed of execution).
Multi-Threaded
A thread is a resource-sharing, lightweight subprocess of a process that is currently operating. And multi-threading is the process of running many threads concurrently. You’ve probably seen numerous processes running in a variety of applications, such as Google Docs, where you can spell-check and autocorrect as you type.
Final Words
We’ve talked about Java’s design goal in this article, namely James Gosling’s desire to create a system-independent language that adheres to the WORA (Write Once, Run Anywhere) philosophy. In addition, we learnt the key characteristics of Java that set it apart from other programming languages. You must have caught a glimpse of Java by now. Along with all of this, we also talked about C++ issues that Java has fixed.
