How to Java

Posted by Zhiko on Feb. 24, 2012, 5:31 p.m.

Okay so, as some people may know if they read that other blog about what people are doing, I'll (hopefully) be starting a programming class in a few months, and that class is going to be using Java all but exclusively.

They do teach it from the ground up, but I'm thinking it would probably be good to familiarize myself with the language ahead of time, so I was wondering if anyone on here knows some good online tutorials or anything to learn Java.

The IDE we'll be using in the class is called Blue Jay or something like that if it matters.

I havent heard of Blue Jay. Ive used eclipse which is decent. Java isnt too bad though, its similar to other languages you may know. Though what is different about java is you use a lot more imports. You also use a little different way of handling arguments and parameters, and the names of some functions is a little similar to VB as opposed to C++.

I found this on a site i found from google: http://www.java-examples.com/hello-world-example and this http://www.java-examples.com/java-class-example

BlueJ is a sort of stripped-down IDE from what I hear - or at least I recall people in classes that require they use it complaining about not having certain automatic debugging things that are in Eclipse..

(Eclipse is nice because it gives suggestions and does some auto-complete things but is also very configurable)

When I was learning Java, I found the official Oracle tutorials (or as they call them, 'trails') very good: http://docs.oracle.com/javase/tutorial/

I had to use jcreator in my high school classes, I tried blue jay but never made anything with it and now I've been using eclipse ever since I started CheeseMod. I've found Java to be a pretty easy language to learn even without tutorials.

Ugh. I'm in an intro programming class right now using java and it fucking sucks. I probably should've asked if I could've taken the next programming course instead since this one assumes you have no prior experience in programming whatsoever. Even though I've just been skipping all the lectures since they're painful to sit in, it still sucks since it's a giant retarded roadblock until I can do the later programming classes. Y'know, the ones that actually sound fucking remotely interesting. If you've got any experience in java/c++/c/etc you'll probably be bored out of your fucking mind for a lot of the first class.Or at least I'm halfway through it and it's still pretty basic. Although I guess it depends on the school but since you mentioned "They do teach it from the ground up" I'm guessing they're not going to be diving into very advanced concepts.

What other languages do you have experience in?

I was going to ask the same thing.

Also, not that it matters, since you're forced to use BlueJ, but I love netbeans. The Eclipse GUI makes me cringe, but the netbeans GUI makes me feel really good inside.

We used BlueJ at my uni in my first CompSci course here, Introduction to Java Programming. It's a stripped-down Java IDE - if you have any programming experience already, you'll outgrow it quickly. They teach Eclipse here, but I've heard good things about NetBeans, too.

As Josea mentioned, the official Oracle tutorials are very handy. I'd suggest sitting down and giving them a good read - and make sure you learn by actually writing code and following through the examples!

Your class is literally going to start from square one in the programming world, so familiarizing yourself with basic terms like classes, methods, and variables if you don't know these already will probably prove useful. As you read and write code, these ideas will be constantly reoccuring and you'll be able to recognize each part with ease. Most of those fundamental ideas are applicable to almost every other programming language (with a bit of finagling with the syntax, of course).

The Oracle tutorials will also provide an introduction to the Object-Oriented Programming paradigm (which is the "wave of the future" or something :P). It will help you understand concepts such as abstraction and inheritance, which are all related to classes and objects… they'll give you real-world examples so that you can wrap your head around it if you're new.

Thanks for all the input, I'll be sure to give those tutorials a try.

@Rob and firestormx: The only other language I'd say I have experience in is GML. Also, BlueJ is for the first semester or maybe the whole first year, but then after that they switch to netbeans.

The IDE you use is irrelevant anyways. What's important is knowing the language itself (I'd even say that it's way more important to know how to compile your programs using the compiler directly instead of using an IDE, that way you learn better what's going on under the hood)

This, also I find the best way to learn anything (not just programming) is to mess around with it, do your own thing with what you are taught. be curious about everything and think "what if I…." a lot.

I too want to learn some Java and C# before I start my computer science course for uni in September, thing is, I sort of want to expand to all languages at once, and I can't decide where to start XD. I tried C++, but that gets complicated pretty fast.

I have also touched on actionscript (not that it really counts), SQL, and VB. so I want to learn more in them too.

But the only language I would say I can really do much in is GML, I want to change that.
