Having done OCR GCSE computing:
It’s just a pseudocode style language that they use in exam questions so that you can understand the question regardless of which language your school had you study (in my case it was VB6 💀). In questions where you are asked to write code, you can use the reference language but realistically you just use the one you learned (although I did it all in python instead)
Not a bug exactly, but about ten years ago I was working as an iOS developer and to get around a major problem introduced by the app designer, I made use of a “private method”, which is something an app supposedly gets rejected for by Apple. I came up with a way of hiding it and had to sweat out the approval period before it went live. Ten years later that shit is still there; I’m sure the developers currently responsible for the app don’t even know it’s there. I normally comment my code with an eye to helping future programmers understand what’s going on and why, but this hack was one where I even obscured the comments.
Objective-C does not enforce method access (e.g. private methods) at the runtime level. If you are sufficiently determined, there are no restrictions on what methods you can call, unlike Java or C# (AFAIK).
Java absolutely lets you do that with Reflections. You’re not supposed to, and it’s painfully slow, but the JVM is only marginally smarter than javac (and that’s saying something) so there’s nothing actually stopping you.
I thought there was security code to stop that kind of thing. Granted, it’s been over 10 years since I’ve done anything with Java more than tinkering with Minecraft mods.
Java did have a Security Manager that can be used to prevent this sort of thing. The original thinking was that the Java runtime would essentially be an OS, and you could have different applets running within the runtime. This required a permission system where you could confine the permissions of parts of a Java program without confining the entire thing; which led to the Java security manager.
Having said that, the Java Security Manager, while an interesting idea, has never been good. The only place it has ever seen significant use was in webapps, where it earned Java the reputation for being insecure. Nowadays, Java webapps are ancient history due to the success of Javascript.
The security manager was depreciated in Java 17, and I believe removed entirely in Java 21.
Grading in red is generally avoided, nowadays. Red is closely associated with failure/danger/bad, and feedback should generally be constructive to help students learn and grow.
I usually like to grade in a bright colour that students are unlikely to pick: purple, green, pink, orange, or maybe light blue (if most students are working in pencil). Brown is poo. Black and dark blue are too common. Yellow is illegible. Red is aggressive.
Anyway, I’m guessing they just graded everything in green. The only time I’ve ever graded in more than one colour was when I needed to subgrade different categories of grades, like thinking/communication/knowledge/application. In that case, choosing a consistent colour for each category makes it easier to score.
Java is extremely widespread in corporate companies - hence the suit and tie. Perl is fair to liken to spelunking deep into a dark cave with only your wits to save you.
PHP seems to be a reference to the fact that it’s extremely common on servers… but it also might be a lazy phpbad joke - it’s pretty weak either way (if you wanted to play into the server characteristic give it a dozen arms serving the entire restaurant in the background).
As a Perl dev, I dunno if that’s how I’d characterize the language, but I’ll take it over yet another “Perl is unreadable line noise lol and what’s the deal with airline food” reference.
Yeah, to be honest you can write good code in any language and it’ll usually look pretty similar… all the perl stereotypes come from having to maintain shell scripts from someone kludging their way through learning to code… it’s the same reason why phpbad, amateurs could get into webdev with php so there’s an impression that all php is the php written by amateurs.
Also, bear in mind that over time these languages have converged through feature additions “LISP has functional programming - why can’t PHP have first class functions… oh traits look neat, let’s add that… you know those statically typed languages sure seem nice…”
I could’ve used a lot of things, but I’m on my phone and I wanted fewer characters to render it, whilst being sure it would work without having to run it.
Also, I am pleased to have maybe helped. Perhaps we can be friends, you and I. Perhaps not. Idk, maybe you punch dogs, why would you do that? Seems mean.
Have you ever just, like, edited a comment? How do people know when you did it? I guess if I were writing a thing to check it I’d use a registry of timestamps and checksums… So, like, ok, you can track, but why, how does it look?
Anyway sorry I had some drinks between now and first post, goodnight
Code as given can be made valid in scala I believe. My starter was based on that assumption. I think raku can do it too, but you would probably have to x = $ to make it work…
Edit: misread your comment slightly, CBA to change mine now. It is what it is
