发帖数: 1011 | 2 typically I only use exceptions for rare happened errors.
Althrough MS said using exceptions would not bring too much performance penalty,
I doubt it. Java will have performance penalty when using exceptions especially
for JIT VMs. You can find infromation from IBM.
If the error is really a "wrong opertions", just use exceptions for good code
management. But don't abuse exceptions. I have seen some guy used exceptions
for the situation that would happen > 20% probability. That's really not

before you start coding?

发帖数: 1011 | 6 depends on how many function models you have.
I like to classify exceptions from their models.
And I always give a way that when end-user administrator
reports us the error message, we can find the exact palce
of that code.
I also wrote exceptions manual in my formal company. :)
