java and c++

[matt271]

hi alls

i am new to OO programming as i just started comp sci this year

i like java cuz its easy, but i want to learn c/c++

one thing i would like to do is write a class in c++ and load it in java and call methods in the c++ class from java

is this possible? can somebody point me in the right direction?

Why yes, yes it is. Check out the Java Native Interface.

Best of luck to you.

It's possible - JNI, as rdrake said.

The better question is why you would want to do that. There are some use-cases where you literally cannot do something in Java and therefore have to do it in another language (frequently C/C++), but those are pretty rare. You've got me curious now.

hiya
id like to ask a couple of questions too
im an 8th and has taken an interest in computer science
of course i cant really get classes and things yet (starting a class in september tho )...so i was wondering well...where should i start?
what should i start off with in computer sciences?
like ive looked at alot of stuff and i think id like to do software engineering...and now im wondering...WHAT DO I NOW?
like im a super begginer...13 year old...

You should probably start with Turing. The download is free, the help is bundled, the error messages are friendly, and there's a community here to help you. Specifically, follow The Turing Tutorial.

Moving from Turing to Java is pretty easy (from personal experience). C++ is an unmitigated horrorshow to for learners, so you should probably stay away from that.

With all due respect to those who've learned Turing in school... why would anyone in their right mind not constrained by a course's curriculum choose Turing over open alternatives like Python, Scheme, etc?

[DemonWasp]

Because I haven't looked at the Python tutorials here, so I have no idea whether they're complete / any good. I also don't know Python.

Besides, you're probably talking about someone who doesn't know what a command line is, so you have to factor that in.

Sounds like we found an excellent place to start!

[wtd]

Tony speaks the truth.

[DemonWasp]

Hmmm...do we have a tutorial for the CLI (particularly on Windows, as that's where I'd assume most of the newbies to be)?

[Sniper4Life]

lol ok
i know what a command line is and i can make only simple cmd files (like once i made the matrix ...1s and 0s going down at a set speed...and colour green...with spaces between em...)..using c++ i made that
i know basic stuff but thats bout it
like i think the most advanced thing i might kno is arrays?
srry i didnt explain better earlier...but cus i had to go to sleep
so i kno basic c++....basic HTML...and ya...just the basics...

[saltpro15]

sinper4life, I assume you mean .exe files? and C++ is an excellent language, but probably not the best one to start with, I would recommend Turing or Python to start

[Sniper4Life]

no i meant batch files...and k ima start with python......

btw...kno any good sites to start with python?

[saltpro15]

well this is what I read to get started, it's good for beginners

[Sniper4Life]

thanks the tutorials are very "noob" friendly
should be pretty easy to learn
thanks saltpro

also its very easy to be because i understand all of these things in c++ so its easy to adapt
