If you develop your own library which makes use of a third-party library that throws an exception. Now there are two options for us: 1. don't catch it (not a better option) 2. catch it and log it somewhere, then rethrow it By rethrowing, we propgate this exception to the caller (client) of your...

Yes, When you catch an exception, it's possible to rethrow it. This is just the same as if you hadn't caught it in the first place - the exception will continue to bubble up through the layers until it reaches some other code that catches it (or it reaches the top of the stack and the program exits)....

This is just the same as if you hadn't caught it in the first place - the exception will continue to bubble up through the layers until it reaches some other code that catches it (or it reaches the top of the stack and the program exits). So why would you do this? Well, it means you have temporary access to the exception at the point where you caught it. One situation I've used this in is where I want to log the fact that an error has occurred, but the real error handling is happening at a higher level. You'd only do this, though, if this local logging could add something useful that the higher level error handling doesn't know about. read less

try { // code here } catch(Exception ex) { throw ex; } but this is not advisable hust catch the same exception and re-throw it. If you want to make your application specific message then you can try this.

Yes you can rethrow an exception by throwing an exception inside catch block provided we are able to catch the Exception properly. If we are not sure what kind of Exception is caught; in that case we can catch the super Excepiton class incatch block and then throw any other exception

What do you mean by rethrow? Are you trying to ask if one can raise the exception again once it's handled in catch? If yes, then yeah we can. We need to use throw keyword. Something like this try{ //code } catch (exception ex) { //log the exception or do whatever you want. throw...
