So you’ve probably been thinking about learning Java for a long time, but you’re not entirely sure if this is the right direction for you. Or maybe you are concerned about the complexity of the learning process. In this post I try to answer the questions that concern you.
Why Java and why on a smartphone?
There are so many programming languages out there! Unsurprisingly, trying to figure out which to choose, you may find yourself confused. Which language will bring the best return on your time and effort? I really believe that Java is one of the best options. Consider it:
- Java is not difficult to learn. It’s not an empty proposition: this language was originally designed to be easy to use.
- Java is a highly developed language. It has a lot of libraries and frameworks especially for each problem. Some of them were developed by Java developers, others by other programmers. Many libraries are free and open source.
- You can apply Java skills almost anywhere: from mobile application development to web application development, from finance to big data.
- Java follows the principle “write once, execute everywhere” (WORA slogan). This means you can write code for Windows PCs and it will work on Linux with minimal or no fixes. You can switch from one system to another and it won’t cause any inconvenience (maybe your brain will say, “Dude, was it okay, why move?” – but it’s not Java’s fault).
- Java developer is one of the most needed jobs in the IT market. Especially in large companies that develop complex systems.
According to Statista, almost 50% of people spend 5-6 hours a day with smartphones (use for work purposes was not included in this figure). Another 22% of those surveyed stated that they had spent 3-4 hours a day with their electronic pocket friends. More and more people want to do something useful on the subway or in line. And for GenZ people, a smartphone is basically the primary medium between them and the rest of the world.
When you’re motivated, your smartphone can help you acquire valuable skills. Coding can be one of them. So many Android applications are required to learn Java these days, all you have to do is choose the most suitable one for you.
Which options are to be considered?
With this app you have access to more than 600 mini-lectures and 1200 programming tasks (approx. 80% of the course are exercises). After you have solved a task, you can immediately check that your solution is correct. More importantly, the app looks more like a game than a traditional, boring study. There are four quests with ten levels each. You will switch from one to the other, improve your programming skills and gain a lot of experience. If you have any questions, you can use the help section, search the blog for an answer, or ask a community of other learners. If you find it difficult to write code on a smartphone, you can use automatic extensions and tips. Also, this app is famous for its very handy mobile IDE.
The app is part of an extensive desktop course – https://codegym.cc/ – with two subscription options. Premium costs $ 49 per month and gives you access to all quests, task recommendations, and much more. And the Premium Pro subscription costs $ 99 per month and also allows you to analyze your coding style. Important note: There is a “mobile only” option that costs much less (for example, $ 60 per 6 months for US users).

Learn Java programming
This app includes tutorials (for both beginners and advanced programmers), coding lessons, and a Q&A section to help you learn the basics. There are many examples that you can use to understand how to write code (100+), armed with professional comments. This app can also help you prepare for the exam in Java. The downside – it’s not gamified, so don’t expect much fun while learning.
The price of the app: free.

The basic version of the app is free. The Pro version costs $ 12.99 per month (or $ 69.99 annually if paid).

Learn Java: Programming
This app is also intended for beginners and offers small lessons that you can work through quickly, lots of practical examples and quizzes to check your learning progress. You can write code in the app and run it in the field. There’s also a feature as helpful as bookmarks that allow you to mark some topics and come back to them when you have the time.
The app is free, but a paid PRO version is available (ad-free, with challenges and the option to get a certificate). The PRO version costs $ 24.99 per year or $ 2.49 per month.

This app is also used to learn several languages (including Java, Python, R). It was made very professionally (developers worked with Google experts). It claims to have the fastest compiler in the world, in addition to lots of coding examples and interactive lessons. The content of the courses is updated regularly.
The basic version is free, but there is also a Pro version that gives you full access to all content (including offline), removes ads, and allows you to receive a certificate. Paid options start at $ 6.99 per month.

Allows you to learn multiple programming languages suitable for both beginners and those with programming experience. The app presents itself as a tailor-made learning coach. This means that you will receive personalized assignments and suggestions for what you would like to learn. This platform is well known and very popular.
There is a free version, but it has a very limited set of tools. You can buy individual access for $ 50 per year (you get access to the mentor community) or $ 350 per year (you have a personal mentor). There are also several paid options for teams.

Not only is this app tailored for Java learners, but you can find a course for beginners that has access to 11 lessons and 7 projects. Users learn basic programming concepts: variables, object-oriented java, conditions and control flow, etc. Some of the content is free, but to access the rest you need to buy a Pro version which costs $ 15.99 monthly if yearly or paid $ 19.99 monthly.

Same situation here: a big, reputable platform that offers hundreds of courses in different programming languages. You can also find several Java courses here, but many of them are not free. All courses have a rating so you can choose the title and author that you find most reliable. In addition, you will find the information not only for beginners, but also for people with different levels of knowledge.
Udemy suggests that new customers join from $ 13.99 per course. By the way, you can even buy a course as a gift (or receive it as a gift if it’s your birthday soon).

The strength of this app are the easy-to-understand video tutorials that make learning exciting. You can watch professionals complete the tasks, start some challenges (if the competition drives you), and solve quizzes. The interface is very user friendly.
The app is free, but you have to earn credits to unlock new assignments due to gamification. Or you can buy the credits, as in many other learning apps.

Java deep learning
It’s an app that will help you not only acquire or improve programming skills, but also face real-world challenges like a job interview. A separate section is dedicated to this topic. The user can learn what questions recruiters ask often and prepare the answers in advance (everyone knows how stressful such interviews can be and how hard it is to think of something smart and smart when there is a need to show how smart and one is smart).
This app is free.

As you can see, the number of options is significant and I’ve only covered 10 of them. Whichever app you choose, remember to invest at least 30 minutes a day learning Java and one day you will be a person providing advice on how to become a programmer.
