What are the limitations of try-with-resources in Java?

What are the limitations of try-with-resources in Java?

While try-with-resources is great for automatic resource management, it has some limitations. For instance, it can only be used with resources that implement the AutoCloseable interface.

Can you give me an example of a situation where it might not work?

Sure! If you have a resource that doesn't implement AutoCloseable, like a regular File object, you can't use try-with-resources for it.

Are there any performance issues associated with it?

Generally, try-with-resources is efficient, but if you have multiple resources, closing them can add overhead. It's best to minimize the number of resources.

What happens if an exception occurs during resource closing?

If an exception occurs while closing a resource, it can suppress the original exception. You can access suppressed exceptions using the getSuppressed() method.
