Programming should be a tool, not an end unto itself.

You do know that the Internet would go to shambles if someone managed to do that that? 20th time? What the fuck are you talking about?

In my experience C++ is superior is most cases. Java is a more like a Duplo language but C# does combine the power C++ has, with the ease of Java in a nice .NET kind of way. Started with C# a few months ago, don't regret it one bit.

Looking past the meme-y nature of Java hate, you really do have to include it in every list of major languages. It's enterprise through and through.

That being said, fuck Java.

Tell me, what is n?

[Anonymous No.7380964]

>>7380799
You mean what is O(n^3)?
Basicly, it is the number of iteration an algorithm will make with n inputs

[Anonymous No.7380967]

>>7380964
what's your measure of input

[Anonymous No.7380994]

If you create a poorly made tool, and then show it to professional tool makers, they will mock it. It doesn't matter how important the job you're doing with it is.

You could save the world with a sword made of cardboard and a coat hanger but swordsmiths are still going to call your sword a piece of poorly made shit.

[Anonymous No.7381009]

>>7380964
I'm pretty sure he meant "what is n?".
I was going to ask the same, it isn't that clear what' the input of "a program that can identify compounds that kill cancer in humans".

Really have to consider that Java is not hard, but a must, if you want to go into any enterprise type of shit, so why not just pick it up while doing other stuff?

Other than that. Yeah, fuck Java.

Hey, I'm a CS major and O(n^3) sounds just fine to me. It's still in polynomial time, and I bet it's appropriate for your input size.

[Anonymous No.7382736]

Lots of Java hate here today.

I really like object oriented design, so Java is perfect for me. Yes it's tedious to use and not as fast as languages that are closer to the processor, but it always has what I want pre-written and easy for me to visualize.

I'm also a big fan of C when I need absolute power. I just so rarely need absolute power.

>CS majors

The majority of CS majors are a bunch of faggot future code monkeys jacking off over their favorite sorting algorithm (even though they just end up calling their language's standard library's sort function anyway). They regurgitate estimates for run times, and bitch and moan because they have to take one or two classes where they actually have to prove these.

Also, programming IS a tool. It's just that most schools are churning out code monkeys rather than computer scientists because it's what they industry wants.

Imagine studying in murica, and playing 4+ years of tuition just to get a programming job. I think things are going to change here with all the trade schools that teach you industry-relevant skills in half that time that keep popping up. Good ones will appear, and nobody will go through a 4 year degree just to become a programmer. Schools will go back to teaching CS to people who care more about CS than about "coding", and everybody will be happy.

>>7382772
I'm not even aware of the meme, I'm almost never on this board.

That being said, Java is run in a virtual machine that is simulated by your processor. The fact that it's a computer on a computer on a computer makes it not as fast.

Also, the print function is the definition of tedium, even though it is well designed for the consistency of the object oriented model.

Java may be insecure and often retarded as fuck, but there's a reason it's ubiquitously used in massive coebases almost everywhere.

People who talk shit on OO and expect the entire world to build software in procedural C are delusional and probably unemployed.
