Greetings:
I have a situation where I need to access a member of a mutable array (max 4 members).
Sometimes I could get an out-of-bounds exception, if for example, I try to access member #3 out of a 2-member array.
It's not serious, I could just ignore it and continue.
Question:
Is it acceptable to merely trap for the out-of-bound exception within the method() and continue my way?
... or should I test EVERY TIME I access a member, to see if the member exist?
The amount of code is less for the @catch() exception route.
This could happen quite frequently.
Thoughts?
Ric.
