Can I catch multiple Java exceptions in the same catch clause?
exception, java, multi-catch, try-catch
Solution
This has been possible since Java 7. The syntax for a multi-catch block is:
try {
...
} catch (IllegalArgumentException | SecurityException | IllegalAccessException |
NoSuchFieldException e) {
someCode();
}
Remember, though, that if all the exceptions belong to the same class hierarchy, you can simply catch that base exception type.
Also note that you cannot catch both `ExceptionA` and `ExceptionB` in the same block if `ExceptionB` is inherited, either directly or indirectly, from `ExceptionA`. The compiler will complain:
Alternatives in a multi-catch statement cannot be related by subclassing
Alternative ExceptionB is a subclass of alternative ExceptionA
The fix for this is to only include the ancestor exception in the exception list, as it will also catch exceptions of the descendant type.
Problem
In Java, I want to do something like this: ``` try { ... } catch (/* code to catch IllegalArgumentException, SecurityException, IllegalAccessException, and NoSuchFieldException at the same time */) { someCode(); } ``` ...instead of: ``` try { ... } catch (IllegalArgumentException e) { someCode(); } catch (SecurityException e) { someCode(); } catch (IllegalAccessException e) { someCode(); } catch (NoSuchFieldException e) { someCode(); } ``` Is there any way to do this?
