What are some common finalizer issues in programming?

What are some common finalizer issues in programming?

Common finalizer issues include resource leaks, performance problems, and unexpected behavior during garbage collection.

Can you explain how resource leaks happen with finalizers?

Resource leaks occur when finalizers are not called, leading to unreleased resources like file handles or database connections.

What can I do to avoid these issues?

To avoid issues, consider using try-with-resources or explicit resource management instead of relying on finalizers.

Are there any best practices for implementing finalizers?

Yes, best practices include keeping finalizers simple, avoiding heavy operations, and using them only when necessary.
