Java's nested try-catch mechanism is a sophisticated error handling feature that allows for multi-layered exception management. It is essential for creating resilient applications, especially when dealing with file I/O or database operations. Best practices include proper catch block ordering and using 'finally' blocks for cleanup. Understanding and implementing these structures can significantly improve code reliability and maintainability.
