I'm diving into a new programming career and have only been studying Java for about four months. While I've been managing the assignments at school, I'm struggling to find alternative practice sites beyond Hackerrank. The initial beginner challenges were manageable, but I'm hitting a wall with the so-called 'easy' challenges and often require help to complete them. I need a platform with beginner-friendly challenges that also provides solutions so I can improve my understanding of Java instead of just memorizing how to answer specific questions. Any recommendations for sites that would be better for beginners?

For a deeper understanding of Java, consider building an API with Java 11 using Spring Boot 2.3 and swagger codegen. Then, challenge yourself to upgrade it to Java 17 and Spring Boot 3.0. Pick any fun idea for the API; I made one for fetching random quotes from historical figures. This project will teach you a lot about modern Java programming and don’t forget to write unit tests!
You might want to focus more on your schoolwork instead of just practicing on sites like Hackerrank. It’s great to get extra practice, but don't let it overwhelm your studies. Just make sure to balance both!
I run out of practice problems really quickly, though! I finish my assignments fast and I still want to hone my skills throughout the week.
This sounds really useful! I’ll definitely look into starting an API project. Thanks a ton!
