We, here at upGrad, believe in a practical approach as theoretical knowledge alone won�t be of help in a real-time work environment. In this article, we will be exploring some interesting Java projects which beginners can work on to put their Java knowledge to test. In this article, you will find 17 top Java project ideas for beginners to get hands-on experience in Java.

But first, let�s address the more pertinent question that must be lurking in your mind: why to build Java projects?

When it comes to careers in software development, it is a must for aspiring developers to work on their own projects. Developing real-world projects is the best way to hone your skills and materialize your theoretical knowledge into practical experience.

Amid the cut-throat competition, an aspiring Java Developers must have hands-on experience with real-world Java projects. In fact, this is one of the primary recruitment criteria for most employers today. As you start working on Java projects, you will not only be able to test your strengths and weaknesses, but you will also gain exposure that can be immensely helpful to boost your career.

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.

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 the 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 the 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.
