Is it possible to catch all exceptions except runtime exceptions?

Question

I have a statement that throws a lot of checked exceptions. I can add all catch blocks for all of them like this:

try {     methodThrowingALotOfDifferentExceptions(); } catch(IOException ex) {     throw new MyCustomInitializationException("Class Resolver could not be initialized.", ex); } catch(ClassCastException ex) {     throw new MyCustomInitializationException("Class Resolver could not be initialized.", ex); } catch... 

I do not like this because they are all handled same way so there is kind of code duplication and also there is a lot of code to write. Instead could catch Exception:

try {     methodThrowingALotOfDifferentExceptions(); } catch(Exception ex) {     throw new MyCustomInitializationException("Class Resolver could not be initialized.", ex); } 

That would be ok, except I want all runtime exceptions to be thrown away without being caught. Is there any solution to this? I was thinking that some clever generic declaration of the type of exception to be caught might do the trick (or maybe not).

Answer 1

You could do the following:

try {     methodThrowingALotOfDifferentExceptions(); } catch(RuntimeException ex) {     throw ex; } catch(Exception ex) {     throw new MyCustomInitializationException("Class Resolver could not be initialized.", ex); } 

Answer 2

If you can use Java 7, you can use a Multi-Catch:

try {   methodThrowingALotOfDifferentExceptions(); } catch(IOException|ClassCastException|... ex) {   throw new MyCustomInitializationException("Class Resolver could not be initialized.", ex); }
