As I said earlier, I was writing C long before I started using Java and 
am still writing quite a bit of C: which language I use depends on the 
sort of task and what the target hardware is [*].

Of course YMMV, but it makes sense for me to make these checks explicit 
in Java because that's what I'm used to doing in C.

[*] I considered writing an 8-bit emulator in Java. Some parts, including 
configurable modularity, would have been really easy in Java, but making 
8 bit register handling  (which required 8 bit unsigned arithmetic plus a 
setting the CC register on overflow, whether bit 0 was set, etc,etc 
turned out to be much easier in C. OTOH a tool for setting up a set of 
club duty rosters was a breeze in Java and would have been bad news in C.
