Try/catch/finally flow, including return in try and finally

A try block contains code that might throw. It must be followed by at least one catch block, a finally block, or both; a try alone does not compile (try-with-resources is the one exception, covered later). Braces are required for every block, even with a single statement. When an exception is thrown in the try, the rest of the try is skipped, and Java checks the catch blocks from top to bottom, running the first one whose type matches. If none matches, the exception propagates to the caller after the finally runs.
