Q: Canadian and US Postal Code (Inheritance) in Java

I have to implement two subclasses for Canadian and US postal code in Java. For Canadian Postal code, a valid postal postal code has the rule: positions at 0,2,5 are letters. Positions at 1,4,6 are digits. Position at 3 is white space. (eg: V9A 7N2) For a valid USA postal code, it starts with two...

Welcome to Stack Overflow. Please read How to Ask and stackoverflow.com/help/on-topic, and note well that this is not a discussion forum. We expect one, clear, specific, directly asked question - not a generic request for "criticism, advice, tips or anything". More broadly, we don't do code review here; you may try Code Review, but they have their own standards for questions. In any event, do not show us IDE screenshots. — Karl Knechtel 37 secs ago

Not really, because generic examples for such imports are strewn across the internet (both good and bad examples, likely). And in your specific case, it is much more likely that you need to rethink your app structure, so that the whole import problem goes away. But that requires much more time, and probably amounts to tutoring, which is not the same as providing a direct solution. A site like codereview might be of help with that, but a review of the full app code could be a bit much. — 9769953 31 secs ago

Q: How to handle errors requiring program termination in Python functions?

I have a main() function in my Python program which calls another function which in turn calls yet another function. There are certain conditions in those functions when the program has to call sys.exit(). One approach is to call the sys.exit() directly from the functions like this: #!/usr/bin/en...

@pacmaninbw I had a couple boomboxes in the 90s, as well as a walkman (which I got out last year during a power outage) and I had a couple discmans (one of which I use for my son's CDs)

pacmaninbw

@SᴀᴍOnᴇᴌᴀ Do you still have cassettes for music? Since I preferred to listen to my own music at work the Walkman was enough, boomboxes would not have met approval from my coworkers. I switched up Metal and Rock with classical Music (ballets and symphonies).

Sᴀᴍ Onᴇᴌᴀ

technically I do have cassettes however the walkman doesn't appear to play them anymore - so it is basically only good for the radio function

Last week our neighbors moved out and had a free pile... one day I saw a boombox with the text "Super Woofer" - hadn't seen one of those before

@SᴀᴍOnᴇᴌᴀ I don't see a CD player on the boombox, the graphic equalizer is nice.

@Mast in my city that might be useful though it might not deter the ones you'd want to deter

@pacmaninbw I think the thing in the middle was a woofer and the 80 had 2 of those.

It's not clear what the inputs and outputs of your program actually are, so it's hard to start thinking about details of how to structure your data. Also, does you code already work? If so, I recommend posting it to codereview.stackexchange.com instead of here. If your code doesn't work, then please give more details so we can help you debug it. — David Grayson 7 secs ago

Q: How do you decide if a function should return data directly (via return statement) or indirectly (e.g. updating a class property) or both?

I'm wondering what the most elegant way of returning this information is. Do I return it directly from the functions as an integer like this? $result...

Q: What are other ways of finding Max and Min in python, other from my method?

How my method works is by sorting the list of numbers from least to greatest, finds the length of the list, then pick the first and last index integers. In the python world is this efficient or is there a better faster way; speed-wise? list = [11,2,343,32324,324,23456,437575,23534654,34624,236543...
