- Can I catch multiple Java exceptions in the same catch clause?
22 If there is a hierarchy of exceptions you can use the base class to catch all subclasses of exceptions In the degenerate case you can catch all Java exceptions with:
- The difference between try catch throw and try catch(e) throw e
The third try-catch block is different When it throws the exception, it will change the source and the stack trace, so that it will appear that the exception has been thrown from this method, from that very line throw e on the method containing that try-catch block
- Difference between catch (Exception), catch () and just catch
Both constructs (catch () being a syntax error, as sh4nx0r rightfully pointed out) behave the same in C# The fact that both are allowed is probably something the language inherited from C++ syntax Others languages, including C++ CLI, can throw objects that do not derive from System Exception In these languages, catch will handle those non-CLS exceptions, but catch (Exception) won't
- Difference between try-finally and try-catch - Stack Overflow
Finally and catch blocks are quite different: Within the catch block you can respond to the thrown exception This block is executed only if there is an unhandled exception and the type matches the one or is subclass of the one specified in the catch block's parameter Finally will be always executed after try and catch blocks whether there is an exception raised or not

- When is finally run if you throw an exception from the catch block?

- c# - Catch multiple exceptions at once? - Stack Overflow
try { WebId = new Guid(queryString["web"]); } catch (FormatException) { WebId = Guid Empty; } catch (OverflowException) { WebId = Guid Empty; } Is there a way to catch both exceptions and only set WebId = Guid Empty once? The given example is rather simple, as it's only a GUID, but imagine code where you modify an object multiple times, and if one of the manipulations fails as expected, you
- Exception thrown inside catch block - will it be caught again?
One related and confusing thing to know is that in a try- [catch]-finally structure, a finally block may throw an exception and if so, any exception thrown by the try or catch block is lost That can be confusing the first time you see it
