Why should you become a
Java Developer?

Java Developer

Java has been taught as the fundamental programming language to computer science and software engineering students of the last decade. That's why companies like Google, Goldman Sachs, IBM and Accenture still bet on it even after the crown as the "most popular" programming language has been passed.

Java can be used in almost all areas of software engineering. Frameworks make it possible to bring Java to the web, it can be used to build mobile applications, as well as high-frequency algorithms and big data architectures.

Java is here to stay and new talent is needed!

Best books to build Java understanding.

A well-written and thorough book can be an amazing path to build deeper understanding and also act as a handbook as you discover the internet's vast resources.

These are our and our experts top picks to get started building career-relevant skills.

Head First Java

Head First Java

Learning a complex new language is no easy task especially when it s an object-oriented computer programming language like Java. You might think the problem is your brain. It seems to have a mind of its own, a mind that doesn't always want to take in the dry, technical stuff you're forced to study.

Clean Code

Clean Code

Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way.

The Java must-reads you shouldn't miss.

Key articles and posts of industry experts can help you get a better picture of what you are getting into.

Java Coding Tips

As Java offers so many features and options to the developers, people are sometimes lured into learning too many things in too little time. As a result of this, they get ‘bits and pieces’ knowledge of a few options that Java offers, but their basics hang on a loose thread.

Trust me when I say this, Java is one programming language which is easy if you have paid attention to the simple basics, however; it can be frustrating if you get greedy and try to take the shorter route forward.
