When should you prefer finalize (deprecated) and cleaners and when should you avoid it?

    // Example demonstrating the usage of Cleaner in Java
    import java.lang.ref.Cleaner;

    public class ResourceHandler {
        private static final Cleaner cleaner = Cleaner.create();
        private final Cleaner.Cleanable cleanable;

        public ResourceHandler() {
            // Register a cleanup action with the Cleaner
            cleanable = cleaner.register(this, () -> {
                // Cleanup logic goes here
                System.out.println("Cleaning up resources...");
            });
        }

        public void useResource() {
            System.out.println("Using resources...");
        }

        public void close() {
            // Explicitly cleaning up resources if needed
            cleanable.clean();
        }

        public static void main(String[] args) {
            ResourceHandler handler = new ResourceHandler();
            handler.useResource();
            handler.close(); // Clean resources manually
        }
    }
