What challenges have you faced when implementing your projects?

When implementing projects in Java, I often encounter challenges such as:

• Memory management and leaks, especially when working with large objects.
• Exception handling and ensuring application stability.
• Integration with external libraries and APIs, where documentation may be lacking.
• Concurrent programming and thread synchronization.
• Performance optimization and response time.

For example, when working with multithreading, it is important to correctly use synchronized or classes from java.util.concurrent to avoid data races.
