Should ArithmeticException
appear before
RunTimeException
in the list of catch
blocks?
Yes.
If RunTimeException
appeared first, then
its catch
block would catch all RunTimeException
s,
including ArithmeticException
s.
A more compact way of showing the hierarchy is:
Exception IOException AWTException RunTimeException ArithmeticException IllegalArgumentException NumberFormatException IndexOutOfBoundsException Others Others
Don't memorize this diagram (for one thing, it is not complete). But look at it to see what it says.
