If a catch block handles multiple exceptions, you can separate them using a pipe (|) and in this case, exception parameter (ex) is final, so you can’t change it. The byte code generated by this feature is smaller and reduce code redundancy.
The syntax oftry catchstatement with a single catch block handling multiple exception types is </> Copy try{//code}catch(Exception1|Exception2|Exception3$e){//code} ReplaceException1,Exception2,Exception3, .., with the type of exceptions that the try block can throw. Please note that the ...
Here, themultiCatch()function has two arguments. The first one is avararg, containing the types of “multiple exceptions.” A function will be executed if any exception in the definedexceptionsoccurs.This function is the second argument:thenDo(). As we can see in the code above, we wrap ...
If you try to raise multiple exceptions, the program will finish after handling the first exception. The rest will never be raised. You can show this using code similar to the following: Python # catch_first_only.py exceptions = [ZeroDivisionError(), FileNotFoundError(), NameError()] num...

Unfortunately, the design of Java goes against this principle in many places. For example, Java has checked and un-checked exceptions, while there should only be checked ones in my opinion (the ones you must catch or declare as throwable). Also, Java allows multiple exception types to be de...
Implements error handling for Transact-SQL similar to the exception handling in C# and C++ languages.
