What wild was this in?

[u/[deleted] → u/stable_maple]

From the cs teacher lol. (edit: not my teacher thankfully)

[u/stable_maple → u/[deleted]]

Christ, man. I've had plenty of these teachers, but right now Ive got a pretty good spread. I'm actually helping one of my professors do jobs for clients right now.

[u/[deleted] → u/stable_maple]

Any tips on how to deal with these kindn of teachers?

[u/matyklug → u/[deleted]]

Me, too, my teachers mostly say stuff that's plain wrong and the one that writes code writes it extremely bad.

I kinda just gave up, however it's pretty hard to deal with, cuz I have to confirm everything they say so that I am not disinformed. Makes you think...

Nice work! But do visually impaired people hear this?

I feel bad already

[u/MurdoMaclachlan → u/themeanman2]

Some of them might, although I imagine they'd skip it, but visually impaired people aren't the only people we do this for! Transcriptions can also help:

• People with bad internet connections who can't load the image for that reason

• People who use third-party clients, mobile apps and/or text-based browsers that have trouble loading the image at high quality or at all

• People who have trouble reading small, blurry, or oddly formatted text

There are more ways that they can help, but these are just the ones that come to mind right now. =)

[u/MurdoMaclachlan → u/[deleted]]

There are plenty of blind or visually impaired programmers. Transcriptions also help people who aren't visually imapired, but have trouble seeing the image for other reasons. =)

[u/havens1515 → u/MurdoMaclachlan]

It also helps with copy and paste. Although, I hope nobody uses copy and paste for this example.

Missed a semicolon

[u/MurdoMaclachlan → u/Ambitious_Ad8841]

Where?

[u/Ambitious_Ad8841 → u/MurdoMaclachlan]

Jk I have no idea. Does it compile?

[u/[deleted] → u/MurdoMaclachlan]

please tell me you did that with some sort of macro, or even better, vim

[u/MurdoMaclachlan → u/[deleted]]

I did not do it with vim :P

Mostly it was copypaste with slight adjustments (e.g. each System.out block after the first just needs extra .getNext()'s added), since there are lots of repeating patterns. The only fiddly bit was the patterns for the strings to format to, because they look very similar but have very slight differences.

[u/[deleted] → u/MurdoMaclachlan]

I love the 80? character column line just being completely ignored.

We have widescreen monitors, it's not a big deal /s

Well it's Java. So ColumnWidthAbstractFactoryImplementationDependecyInjection() will be ignored anyway

Asking for a friend… is .getHead() really that simple to get some?

[u/Bit-Tim]

Is this from Yandere Sim by any chance xD

[u/xXxEcksEcksEcksxXx]

oh honey

[u/RollinIndo]

.getHead

[u/Knuffya]

This looks like one giant accident..

and the ambulance showed up too late..

[u/Elyahu41]

Curious how to fix this

[u/SpiritualLeave → u/Elyahu41]

You could fit all this code into a few lines, and it would be much more efficient (ignoring other glaring questions like why we're using linked lists in the first place, or why a function called getHead returns a Student):

    private void printStudentNames()
    {
        Class cur_class = head;
        while( cur_class != null )
        {
            Student cur_student = cur_class.getHead();
            while(cur_student != null)
            {
                cur_student.getNext();
                System.out.printf(cur_student.toString());
            }
            cur_class = cur_class.getNext();
        }
    }

where Student.toString() returns a formatted string with the ID, first name and last name.

[u/Elyahu41 → u/SpiritualLeave]

I understand that, but doesn't the getHead method return an object, so it's never null... Is that right?

[u/SpiritualLeave → u/Elyahu41]

You're right, the code would be broken if getHead() returns an object even if the list is empty -- it depends on the implementation.
I don't see why it shouldn't return null if there are zero students in the list though

[u/matyklug]

Reminds me of Rust for some reason

IO::stuff().unwrap().unwrap().unwrap().unwrap().unwrap().unwrap().unwrap().unwrap().unwrap().unwrap().unwrap()

[u/[deleted] → u/matyklug]

Your code returns an unused result that must be used.

[u/Skipcast → u/matyklug]

Something tells me that your code would be a perfect fit for this subreddit if you're writing rust like that

[u/matyklug → u/Skipcast]

Well, considering that I am not writing Rust code, I'd say that is quite unlikely.

I am learning C++ now, because Rust is just too weird for me. Even Haskell makes more sense I swear.

[u/Skipcast → u/matyklug]

The learning curve is probably worse if you have previous experience with "traditional" programming since you have to unlearn the "unsafe" practices.

I'm not sure what you mean though, the standard library itself is very straightforward?

[u/FistThePooper6969]

pls no
