How about portability of arithmetic? In Java, int is always exactly 32
bits 2's complement. In Ada, Integer is whatever the machine supports.
And if I say "type T is range 1..100;" I might get 32-bit arithmetic, or
I might get 8-bit arithmetic, or who-knows-what. In Java, 64-bit
integers are supported, and no more. In Ada, 64-bit integers are
supported by GNAT, but not by other compilers. A compiler could support
more, or less, according to its whim. Is "type T is range 1..10**10;"
legal? It is on *some* Ada compilers, but not others.
On the other hand, at least Ada notifies you of overflows -- in Java, it
just silently gets the wrong answer. (This is the C and C++ culture --
Java inherits much more than just syntax from that culture.)
