Yesterday the “Advanced Java” class just started actually coding. I thought the class would be interesting, as there are people with so much experience in the room. People with a masters degree in something or other who used computers extensively back in the punchcard days, etc. There’s a guy who had worked at IBM for ten years. I couldn’t believe it! Why are they taking a Java class at Front Range?
But after they actually started programming, it became painfully obvious that I was the best programmer in the room. Not obvious to them (yet :-), just to myself. We’re designing this GUI database interface with labels that change based on the locale. And the teacher’s solution kept a JLabel variable for each label! When he wanted to change the locale of each label, the code looked like:
updateLocale(languageLabel, locale); updateLocale(savingsLabel, locale); updateLocale(contribLabel, locale); updateLocale(incomeLabel, locale); updateLocale(currentAgeLabel, locale); updateLocale(retireAgeLabel, locale); updateLocale(deathAgeLabel, locale);
Ugh (And I hate camelCase, but alas, ’tis the Java way). And he had this sort of thing in three places in the program. What a nightmare to maintain! And he didn’t even align them!
Thankfully, we don’t have to use his code. Most everyone did it the way he did. I put them in a list and looped through them when I needed to. The teacher “blames” that on my Perl origin.
This should be a fun class, though, because there are few programming projects that are monotonous unless a specific coding technique is enforced, which it isn’t (well, as much as Java doesn’t). It’s always interesting to come up with a design that significantly reduces my workload.
