Ruby Programming Tutorial 2 - Object Orientation

[cashjamesPremium1]

i put gem install rubygame but it said it needs build tools and need to update my path

[cashjamesPremium1]

I have been trying to assign the rubygame command in the command line of cmd prompt but need to update a path as the Devkit failed. i have tried to update it but failed. anyone know how

You have the most awesome accent for teaching, my friend. I really liked listening to this. I'm a Perl programmer who's trying to pick up Ruby because it's so much cleaner than Perl for group projects.

I should be preparing for my exam, but this is far more interesting!

Right, honest opinion... what is the commercial value of learning Ruby over languages such as Java or C#?

[you123123123123]

@Caveej

i dont know much about c#, but i know that java is WAY different then ruby, because

1. it's compiled

2. you have to declare all variables before using them

3. its hella corporate and way more low level than ruby

people alway try comparing ruby to java and java to c++.

you cant do that, their different.

i guess python is the closest you could get to ruby, but java is completely different

[Julien1345]

@you123123123123 java is compiled to bytecode not machinecode, and the bytecode gets interpreted (python as far as i know also compiles to bytecode internally butas a programer you don't see this process (don't know about ruby). An really import difference is objectorientation. In ruby everything is an object. You don't have primitive datatypes like in Java and Ruby has dynamic typing. And also why should you compare something thats the same. If it would be the same, would be no need to compare

@Caveej Sorry for the bump, it depends on what you want to do. Ruby is a very nice language for browser embedded programs. Ruby on Rails is one of the programs used to make applications and games on facebook. It all depends on what kind of work you are looking to do. If you want to do freelance programming I would suggest learning all three. (Although C# is almost exclusive to microsoft, C++ is more desired for computer based programs.) If you want to make money using facebook learn ruby.

[earlbedfordjr83]

@Caveej I have no idea what uses java actually has, as I really have never bothered to research the programming language. I know it was used by mobile phones for apps, and you could make blackberry apps using java still. There are a lot of freelance jobs available for flash and java programmers. Amazon supports ruby for their webstore app thing that helps amazon sellers use your program. It is all about what you want to do.

@Caveej Learn as many as you can. Ruby is a great language and it is being used by tech companies now a days, but most likely, like many similar languages, it will go out of style. Java, C, C++, are good languages to have a firm knowledge of.

[OnlyInNaziGermany]

I know PHP :P

[GastroGreen]

lol i know all languages and I am 2

[Aggregate02]

When you create a variable with the @ (like @variable), is it similar to Java when you declare a variable outside a function like: public int variable; ?

[WOWNumansi]

Lol I know c#, Java, Batch and Html at 13 years old.I'm going to start learning lua/Ruby.

[BacklTrack]

@WOWNumansi

Don't count Batch and HTML. but C#/Java is useful, and i would doubt you actually know C# and Java though. Especially at 13, I could believe you had the basics down . But im pretty confident you don't know too much about threading , structures , REGEX and so on and so forth.

But keep it up! Programming is a great experience.

[WOWNumansi]

@BacklTrack Well as for c# I can write a compiler so ye I know Regex ext. like my back hand as for Java well I know up to structures in Java lol,programming rules!

[BacklTrack]

@WOWNumansi

Really? A compiler.. for what language. Would you mind uploading a video or some source code?

[WOWNumansi]

@BacklTrack The compiler would be for my own language which I am developing and yes I'll do some vids on it, so subscribe and I'll get back to you when their finished.

Thanks for some of the best introductory Ruby/OO tutorials I've seen. Really great explanations and step by step instruction. Great work.

[spadict]

Fantastic explanation of object oriented programming for beginners. This has really helped me get my head around that concept much better.

[daeheadshot]

Hahaha nice im starting to learn python now :)

im thinking of Cross learning ruby and python (learning them at the same time) :3
