There’s a common misconception in software development that you have to spend hours at the office, chained to a PC and coding books to learn a new programming language. The good news is, with the impressive development of mobile coding education, you can learn on your feet and combine professional development with running personal errands. 
Whether you’re an experienced or a novice developer who wants to improve, there are mobile apps to learn Java. Let’s take a closer look at the most popular learning tools on the market.

The interface is minimalistic and intuitive. There are four tabs: ‘Learn’, with free coding lessons, ‘Play’ - here, you can challenge other users in online battles, ‘Code’ - a built-in integrated development environment, ‘Discuss’ - a forum where developers share tips and answer questions.
