Search - "bluej"
My teacher at school who taught me programming. We were taught Java.
You see, Java is not a beginner's language, most say. But the way she taught it, the examples, the analogy, the explanation; she made it so easy.
She made us execute our first Hello World program (using BlueJ) and proudly said, "you're all programmers now!", that was when fascination took me over. I remember that moment till today.
Also, unlike regular exams, the programming exams required extreme competency. Marks were split up for algorithm and syntax. There were also questions like find the error in this algorithm for this output. She would always surprise us at the exams!
I had several glorious moments in class by being the first to answer most of her questions. At 13, it was kind of a big deal for me.
(Okay, who am I kidding, it still is :-P)
It was mostly just self learning from there. I switched schools and then there was college. Attending classes in college was like going to the gym with fat trainers. Utterly useless :-/ It just made me appreciate her even more.6
We've got a new CS teacher this year, and she wants to teach us how to use a step debugger. But, instead of using eclipse or IntelliJ, she thinks we should all use BlueJ, which is just as bad as fucking JCreator! Why do schools, particularly highschools, use these shitty ass IDEs? IntelliJ has a free community version. And I'm pretty sure that Eclipse is just free. Why the fuck aren't we using either of those?!5
So once in school, I went to my CS lab to find my friend cursing under his breath. On asking him, he tells me that he can't figure out how to print his code in BlueJ(our school requires us to use BlueJ). So I told him to download another IDE and use that instead. He had a look of bewilderment in his eyes and asked me what an IDE is. He was absolutely shocked to learn that you could write Java programs elsewhere.
P.S This was our fourth year of Java4
Having to use BlueJ makes me want to jump off a bridge. :)
Stupid fucking editor tells me I have errors in my code, even though it compiles without problems using the Java command.1
I found this funny, or my dev-humor is just really bad :>
Friend: Java and BlueJ.
Friend: Why you indicate relationships between classes that have no relationships.
Friend: Fu BueJ
Me: It's called a crush :wink:
Precision: As in having a crush on a person, but no relationship :)1
So today our informatics showed us how to download a file from the internet using Firefox.
It was BlueJ...
So he told us the people who develop BlueJ randomly include the JDK in BlueJ or don't.
He told us it's a bit like Russian roulette whether JDK will be included or not.
What he didn't know,
the standalone version for Windows obviously included it (.exe... ) and the version for other systems doesn't include the JDK.....3
OKAY WHAT THE FUCK JAVA.
At school we were assigned the task to do Huffman's algorithm. Since I am way ahead of all the others, I made a GUI for that. (Btw, we use BlueJ for Java, it's just painful)
Now... I made a JTextField to put the output, which would be any character from 0x0 to 0xFFFF, into it.
Apparently, there is a bug in the setText method, which throws random NullPointerExceptions right into your face if you give it those Unicode characters.
So I looked it up:
It was a Bug, in JDK 1.6.something, where putting a 0xFFFF together with a 0x10000 would cause this. Now you may think, do we still have 1.6? No, we have 1.8 v171, WHY THE FUCK DOES THIS SHIT GIVE ME A NPE?! THE WORST PART IS I CAN'T DO ANYTHING ABOUT IT!
AND IT HAS THE WORST UNDEFINED BEHAVIOR:
1. NPE, nothing else happens
2. The Text box just gets invisible, but the border stays visible + NPE
3. The box completely disappears + NPE
Try-catching it doesn't do anything, everytime I fill the box with text, one of those options happens, and the box was never to be seen again! NOT EVEN CREATING A NEW TEXT BOX AND ADDING IT TO MY WINDOW WORKS.7
Teacher at university told us to install bluej in a Java class. Never in my life have I seen something so irritating as this crappy thing. Your code can have 0 errors and it still doesnt compile.
Alright, epic throwback to high school
-So I'm taking this CS course on java
-Teacher seems legit
-Knows his shit
-Gets the job done
-Introduces the class to an IDE
-I whip out my Eclipse Oxygen (with Hello World preloaded, obviously) like the nerd I am
-Literally the worst editor ever
-And teacher somehow expects us to work in it with git
For those of you who have never worked with BlueJ, thank God you haven't.
What new languages should I learn? I'm working on C++, but PHP seems fun...11
Music, but if it has words they need to be foreign. J-rock, deadmau5, gogo penguin, carrion... All are good.
Dark themes everywhere unless it's java, because it helps me compartmentalise my languages.
Second screen hooked up with the stuff I want to be viewable all the time, as it doesn't change when I switch workspaces. (bug or a feauture?)
Door shut to muffle sounds from the rest of the house, window slightly open so I don't suffocate.
Pomodoro timer on, but put phone into silent mode so no notifications disrupt my focus.
Drinks and bathroom breaks happen in the 5 minutes between pomodoro sprints. Food happens in the 15 minute breaks.
Extra RAM stick is in the mail so I lose less time waiting for android studio to exhale or whatever it's doing as it holds up the whole computer.
I might just do the java parts of my project in bluej if this ram stick doesn't alleviate my problems. I could go outside and drink mud through a metre long straw with a filter on the end sooner than android studio gets unstuck.
If anyone can add more sensible ideas I'd be happy :)1
I freaking hate slow IDEs, especially ones made in Java.
I used to use an IDE/text editor called geany, and it was great, you could do almost every language in it and it worked great. It was fast, and efficient, it was a no-nonsense editor. That was when I was a kid, but I got in univ and got a job, so I had to start using big boy """""enterprise""""" IDEs like eclipse.
Eclipse, netbeans, and intellij (basically every Java based IDE except BlueJ) are exactly what is wrong with IDEs. They are clunky editors that frankly would be better off gone. They are slow, eat RAM like crazy (like most Java software). You just CANNOT have eclipse open for extended periods of time, because it WILL take up too much resources and get slow as heck. Android Studio (based on intellij) is a nightmare to work with. It just does not want to cooperate with you (I will agree they have improved a lot though).
I cannot believe I am saying this, but even the electron based IDEs like atom and code-oss are better than them. They are very easily expandable, something that Java was supposed to be, but is not. They have tons of plugins. Even if its not there, you can make one without having to spend a lifetime making the plugin! They look good. I never thought that going from IDEs with """""enterprise""""" UIs to something modern like code-oss would feel this great. Its ridiculous, I don't want to create a darn project for every single file that I want to edit, I just want syntax highlighting for a single .sh file that I want to edit right now. A project is just a way to logically define what is one "unit" or a "container for multiple files", you know what else is that? A simple directory.
Also I don't want 9 billion .xml files for the IDE to store its crap. Just make a .vscode like folder to hide your shit.12
A friend frequently asks me for help with Java homework.
Today we spent half an hour figuring out how to use some ass-backwards linked list implementation his lecturer provided.
The list itself acted like an iterator, keeping track of a 'current' element that had to be reset to the list's head manually every time you want to iterate over the list. There were insert and append methods that call each other for no good reason and most methods would throw the same generic checked exception.
Also they're told to use BlueJ which has the ugliest debugging tools i've ever seen.3
Why many students use bluej while eclipse is far better?
I want to be a programmer so, in future probably I will join any college or something.
So, I want to know what is special in bluej That eclipse can't fulfill?5
University asks for a uml diagram as a companion for the project files (which need to be in bluej format, FML cancerous ide..)
BlueJ for Java and the IDLE for Python.
No big difference to coding in NotePad.
Just don't understand, why IDEs for learning purposes are that feature-less.
"Hey, you want to learn to code in that specifc language? It would be a shame, if you have to do almost anything by yourself."4
Not a rant, but was wondering:
If I undervolt Ryzen 5 3600 using Ryzen Master from windows, do I get the changes when I boot into my Linux distro? 🤔9
*through gritted teeth* BLUEJ WHATS UR FKIN PRBLM. DON'T LET ME MAKE SOMETHING THAT WORKS IN YOUR OWN COMMAND LINE BUT NOT MY TERMINAL.
I just want to read a single integer from System.in on different occasions during the same program. You even let me close System.in without a warning and try to reopen it later, which I'VE LEARNED ISN'T SUPPOSED TO WORK. EVER.
BlueJ you have beautiful bracket highlighting but that's it, I'm leaving.
What the shit javac let's me compile this without warnings from command line?2
