What resources and sources do you use to learn Java?

To learn Java, I use the following resources:

• Official Oracle Documentation — the best source for understanding standard libraries and new language features.
• Books — for example, "Effective Java" by Joshua Bloch for an in-depth understanding of best practices.
• Online courses — platforms like Coursera, Udemy, where you can take structured courses with practical exercises.
• Practical projects and tasks — solving problems on LeetCode, HackerRank, and also writing small projects to reinforce knowledge.
• Communities and forums — Stack Overflow, Reddit, specialized chats and groups in Telegram for sharing experiences and solving problems.

This comprehensive approach helps not only to learn the syntax but also to understand best practices and modern tools of the Java ecosystem.
