Questions about organizing catch statements in a catch block - compiler specific language or language?

Question

I am currently using Visual Studio Express C ++ 2008, and I have some questions about ordering catch blocks. Unfortunately, I could not find the answer on the Internet, so I ask these questions to experts.

I notice that if catch (...) does not fit at the end of the catch block, compilation will fail with error C2311. For example, the following compilation:

catch (MyException)
{
}
catch (...)
{
}

while the following:

catch (...)
{
}
catch (MyException)
{
}

and. May I ask if this is defined in the C ++ language standard, or if it is just a Microsoft compiler that is strict?

b. Does C # and Java have the same rules?
