A quite big drawback of try-catch-finally that we have to close resource at the end, otherwise the resource remains locked - not always, but sometimes! So either we try not to forget to close the resouce, and place finally at the end, or apply something that does this job instead of us. Try-Catch-Finally The hard part comes in finally, which encloses a try-catch, and null check is very easy to forget. https://torokmark.github.io/posts/do-you-know-java-catch-multiple-exceptions/ Wed, 25 Mar 2020 12:00:00 +0100 https://torokmark.github.io/posts/do-you-know-java-catch-multiple-exceptions/ Catching multiple exceptions is very useful when we are intended to do the same operations when they are raised. The feature introduced in Java 7 and by using it we can place exceptions in the same catch branch. The old way looked like as follows. try { } catch (SQLException ex) { logger.log(ex); } catch (RemoteException ex) { logger.log(ex); } catch (NullPointerException ex) { logger.log(ex); } In Java 7 and onwards, we can place multiple exceptions in one catch branch.
