CodeGym: learn Java

The mobile solution aims to gamify the learning experience and make it more interactive. For this reason, it tries to capture users' attention through its colorful interface and carefully selected content. Moreover, it displays dozens of valuable tips to provide everyone with clear guidance after signing up for an account.
Users must go through four different sections to master the fundamentals of Java programming. Each of them gets the chance to unlock these chapters and the associated lessons at their own pace. However, it is worth noting that the app lets them advance to higher levels only in a predefined sequence.
The creators of CodeGym want to ensure this way that all learners receive the necessary information in the correct order. They can go through previous lessons again at any time in the future, complete coding tasks within the built-in IDE (Integrated Development Environments), and get instant feedback regarding their solutions.
Furthermore, users may keep track of their progress and achievements, set daily reminders to continue learning, and switch to the dark mode to prevent eye fatigue. They can also join various groups and chat with other community members about coding topics.
