What books on programming do you plan to study or recommend for improving your knowledge?

To improve your knowledge in Java programming, I recommend the following books:

• "Effective Java" by Joshua Bloch — a classic that helps write higher quality and more efficient code.
• "Java Concurrency in Practice" by Brian Goetz — for understanding multithreading and parallelism.
• "Clean Code" by Robert Martin — about writing clean, maintainable code.
• "Head First Java" by Kathy Sierra and Bert Bates — good for beginners, explains the basics of Java in an accessible way.

It is also useful to study the official documentation and practice solving real-world tasks and projects.
