Finally always executes. That’s what it’s for, which means its return value gets used in your case. You’ll want to change your code so it’s more like this: function example() { var returnState = false; // initialization value is really up to the design try { returnState = true; } catch { returnState = false; … Read more
Write a SQLUtils class that contains static closeQuietly methods that catch and log such exceptions, then use as appropriate. You’ll end up with something that reads like this: public class SQLUtils { private static Log log = LogFactory.getLog(SQLUtils.class); public static void closeQuietly(Connection connection) { try { if (connection != null) { connection.close(); } } catch … Read more
If you call System.exit() the program exits immediately without finally being called. A JVM Crash e.g. Segmentation Fault, will also prevent finally being called. i.e. the JVM stops immediately at this point and produces a crash report. An infinite loop would also prevent a finally being called. The finally block is always called when a … Read more
Well, for one thing, if you RETURN inside your try block, the finally will still run, but code listed below the try-catch-finally block will not.
No. System.exit(0) doesn’t return, and the finally block is not executed. System.exit(int) can throw a SecurityException. If that happens, the finally block will be executed. And since the same principal is calling the same method from the same code base, another SecurityException is likely to be thrown from the second call. Here’s an example of … Read more
finally executes every*† time Regardless of errors, exceptions, or even return statements, the finally block of code will run. *It will not run if the try or catch blocks execute die/exit. Exception One example is closing a database connection in a process that might otherwise leave a dangling connection that blocks the database server from … Read more
In general, no, this is not an anti-pattern. The point of finally blocks is to make sure stuff gets cleaned up whether an exception is thrown or not. The whole point of exception handling is that, if you can’t deal with it, you let it bubble up to someone who can, through the relatively clean … Read more
If you are thinking about the SWIFT 2.0 error handling to be the same thing as exception you are missunderstanding. This is not exception, this is an error that conforms to a protocol called ErrorType. The purpose of the block is to intercept the error thrown by a throwing function or method. Basically there is … Read more
There is no automatic way provided by Java. You could use a boolean flag: boolean success = false; try { reportStartWorkflow(); doThis(); doThat(); workHarder(); success = true; } finally { if (!success) System.out.println(“No success”); }
Click on the File menu, open Project Structure, then under “Settings” there should be “Project”. Within that tab, there’ll be an SDK Settings option which specifies the language version you want to use. See the JetBrains help page for more details (“Project language level”).
