How does try-with-resources improve exception-safe resource handling?

try-with-resources closes objects implementing AutoCloseable when the scope exits, including when the body throws. Resources close in reverse declaration order. If the body throws and closing also throws, the original exception remains primary and the close failure is available as a suppressed exception. This is more reliable than manually closing only on the success path. Use it for files, streams, and database resources that require explicit cleanup. Garbage collection manages reachable memory, but it does not provide timely release of these exte al resources.
