Why Java?

Although Java is a relatively new programming language (it was launched in the early 1990s), it has created a unique niche in the IT industry. Java is the driving force behind some of the largest organizations, including Airbnb, Uber, eBay, Pinterest, Groupon, Spotify, Intel, Symantec, TCS, Infosys, Wipro, Flipkart, and TripAdvisor, to name a few.

As an OOP language, Java has a modular structure, making solving complex problems significantly easier. Thus, programmers can write reusable codes with Java, enhancing the development process. Additionally, Java offers various features, such as polymorphism, abstraction, inheritance, and encapsulation, that further simplify the code-writing process. Easy to program and run, Java-based applications can be developed to operate on one computer as well as multiple client and server systems within a network.

The five main reasons for Java’s popularity are:

• Platform independence – Java runs on the WORA (Writing Once, Run Anywhere). A Java code is compiled into an intermediate format (a.k.a. bytecode), which is then executed in the JVM (Java Virtual Machine). So, any system running a JVM can execute Java code. Furthermore, JRE (Java Runtime Environment) is compatible with all three operating systems – Linux, macOS, and Windows.
• Multi-threaded – Java has inbuilt multithreading capabilities, which means that you can develop highly interactive and responsive apps with multiple concurrent threads of activity using Java.
• Object-oriented – Java is a purely object-oriented language. Inspired by C and C++, Java extends the functionality of these languages to become a pure object-oriented programming language. Abstraction, encapsulation, inheritance, and polymorphism are some of its core OOP features. 
• Secure – When it comes to safety, Java incorporates a host of safety features into the runtime systems, including runtime checking and static type-checking at the time of compilation. With these features in place, it is pretty challenging to hack into a Java application from an external source.
• Robust – Java leverages a simple memory management model reinforced by automatic garbage collection. Since Java objects do not require external references, Java code is robust. Besides, it also encourages developers to adopt productive programming habits for developing secure and reliable applications. The more you experiment with different java projects, the more knowledge you gain.
• Open source – Java’s position as the second most trending programming language worldwide (IEEE Spectrum) in 2023 primarily rests on it being freely available for use; in other words, it is open source. This makes it ideal for developers and programmers of various competencies looking to build apps of their own. They can even access the latest versions of Oracle JDK and Open JDK free of charge through the Java Development Kit.
• API rich – Consisting of approximately 52 keywords, Java boasts a rich and extensive API (Application Programming Interface). Thus, making projects in Java is easy, with a multitude of methods available for use in any program directly. Developers can accomplish any task with Java API methods, whether handling output input, networking, processing XML, or connecting to databases.
• Community backup – Java’s robust and active community is among the many reasons for its continuing popularity. The Java Community, Stack Overflow, and Java in General are some of the top communities where developers and beginners alike can find assistance when faced with a problem. If you are developing core Java projects or seeking project ideas for Java, you can find extensive and reliable support on these websites from expert developers.
• Documentation support – Another factor contributing to Java’s immense popularity is its detailed documentation feature. Javadoc, a well-documented guide, provides solutions to developers who face problems while coding any application or program.
• Development tools – In addition to frameworks, integrated development environments (IDE), and profilers, Java has an arsenal of various automation, debugging, and editing tools. Java has tools for every type of development project along with various stages of development. Different projects in Java require the use of different tools. These include Maven for building applications, Jenkins for integration and delivery, JIRA for bug tracking and planning, and Splunk for monitoring, to name a few.
• User-friendly – Java offers an easy learning curve with its simple English syntax and use of minimum special characters. This makes it easy for beginners and professionals to master this language. Basic knowledge of programming languages like C and C++ is all that is needed to learn Java and build projects using Java later. Resources are readily available online on various websites, mostly for free.
