Can I use try-with-resources for custom resources?

Can I use try-with-resources for custom resources in Java?

Yes, you can use try-with-resources for custom resources as long as your class implements the AutoCloseable interface.

What does it mean to implement AutoCloseable?

Implementing AutoCloseable means you need to define a close() method in your class, which will be called automatically.

Can you give me an example of a custom resource?

Sure! For instance, if you create a class that manages a database connection, you can implement AutoCloseable to ensure it closes properly.

Are there any limitations I should be aware of?

One limitation is that if your close() method throws an exception, it can suppress other exceptions that occur in the try block.
