Java has been one of the most widely used programming languages of the past two decades. In return, there are job opportunities en masse at some of the biggest companies in the world.
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! Great developers are uniquely situated to get into engineering management positions too.
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
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.
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.
Java has changed dramatically since the previous edition of Effective Java was published shortly after the release of Java 6. This Jolt award-winning classic has now been thoroughly updated to take full advantage of the latest language and library features. The support in modern Java for multiple paradigms increases the need for specific best-practices advice, and this book delivers.
In test driven development, you first write an executable test of what your application code must do. Only then do you write the code itself and, with the test spurring you on, you improve your design.
Coding and testing are often considered separate areas of expertise. In this comprehensive guide, author and Java expert Scott Oaks takes the approach that anyone who works with Java should be equally adept at understanding how code behaves in the JVM, as well as the tunings likely to help its performance.
These days, courses are no longer a sequence of videos. They are
usually accompanied by projects and
a
learning community, keeping you accountable and on the path.
Our
experts recommend these
courses, from
free
selections to paid programs.
CodeGym
There are tons of good books on the Internet, but you won't become a programmer by reading books. To learn Java and become a programmer, you need to write a lot of code.
CodeGym is an online Java programming course consisting of 80% practice and 20% of the essential Java theory. This is what you need to become a real Java developer.
This course provides complete coverage of the Java programming language and serves as a strong foundation for all Java-based development environments including client-based, server-side, and Android.

Key articles and posts of industry experts can help you get a better picture of what you are getting
into.
In our opinion, these are some must-reads you really shouldn't miss.
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.
On the way to your first coding interview? This is a collection of some of the most common coding, algorithm and engineering questions. Your perfect preparation for your interview!
In the end, advancing your career is all about getting the right opportunities at the right time and
a
good portion of luck.
These are some interesting things going on in the Java space and you
probably don't want to miss them.
Get into open-source
The world thrives on open-source software and this is no exception. Core contributors to core libraries and fast-growing tech like React, scikit-learn, Bitcoin and TensorFlow prove their abilities by going into the inner workings of a framework to improve it. For many companies, that's a desirable skill!
These projects are always looking for fresh faces. Grab an issue from the issue board or review a PR to get started!
For many years, Java was the one programming language you could use to build mobile applications. While today, you can use a wider variety of technologies, Google still builds on the tech.
Growing into a Senior Java Developer role pays off –
$30,000 up to per year.
Not only is the progression from individual Java Developer to a Senior role a natural
progression, it
also makes all the difference in your average salary.
On a global average, Senior Java Developer receive a
$30,000
salary hike over entry-level Java Developers when they go from individual contributor to
senior personnel.
