| Subject: Handling error cases |
|
|
| Q:Do we need to handle the case where input doesn't make sense (e.g. there is a plus node with no children)?
A:Only handle the cases that the DoIt.java driver file brings up and test. Normally you would check for things like this, but we are not testing that issue here.
Q:Is it ok to get "infinity" as a result of a divide by zero (that is, do we need to throw an exception or something)?
A: Try it out, you will see that java handles this for you by making Infinity part of the int datatype. So, you don't have to worry.
