Try and Catch

1. Never leave an empty catch in a try and catch block: catch (FileNotFoundException fileNotFoundException) { } 2. Output the log:

catch (FileNotFoundException fileNotFoundException) { log.err(“File was not found” + fileNotFoundException.getStackTrace()); System.err.println(“File was not found” + FileNotFoundException.getStackTrace()”); …

3. Inside the catch, return a value that alters the application flow. For example, redirect user to a page “Server temporarily not available”. 4. Do not wrap the whole method in a try and catch block 5. Do not use generic Exception , if more specific exceptions are available. 6. Use method() throws Exception very cautiously and only when there is a very good reason
