Java

[Gleb]

As a part of my school lessons, we learn to work with the Java language.
Does anyone know any helpful web-sites connected with the topic?

Recently we started working with several pages simultaneously, and this is really complicated.

Thanks.

http://www.w3schools.com/js/default.asp

w3schools is a useful reference for any language commonly used with web design. I may come across something else later but I haven't actually used Java much (skipped it and went straight to PHP) so I don't know of another off hand.

Re: Java

Are we talking Java or JS? I'm guessing what's meant here is Javascript because of Gleb's description, but I'll post a link for Java, too.

This is a good JS page: https://developer.mozilla.org/en-US/...ted_JavaScript. I like this site, too: http://www.tutorialspoint.com/javascript/. I've also used this last site to pick up C# and Ruby. SitePoint is supposed to be good: http://www.sitepoint.com/javascript/.

For Java, you can't beat Oracle's page: http://docs.oracle.com/javase/tutorial/.

So, are you learning to be a web dev, Gleb? That's pretty cool. ^_^ Web dev is fun stuff.

Re: Java

I just learn the language, it's not easy, but interesting!:yesss:
The exercises in the exams are sometimes beyond the level of insane, but I am not gonna quit learning.

From time to time, we master the exercises of the final exam, that every student must pass. Every time the level becomes harder (a bit), but I don't complain
Oh and thanks for the links!

Hey, no problem. Yeah, I feel your pain. Software/web development is a lot of fun, but it's also frustrating, too.

This is how the program we work with looks like.

Re: Java

Looks like it might be a higher quality IDE than the one I got stuck with when I was first learning. (JGrasp) Any Java IDE that renames the "bin" folder to "classes" needs to be buried in the woods somewhere.

Re: Java

Of course Just wanted to show the program, since I don't know the difference between ordinary Java and Javascript - it looks a bit similar to me.

Re: Java

like MO, I would point you to w3schools... but more importantly, I would point you away from the evils of Java. As a programming language, it is a wicked temptress. It draws you in with simple syntax and cross-platform interoperability... then it strikes your users with unexpected security holes that you have no control over.

Just say not to Java.

Re: Java

I can't change the learning program... It is really bothersome a bit, but it is also a bit easier for me than C or C-sharp languages.

LOL. Java's actually improved quite a lot. J7 is great and J8 supposed to be super awesome, too. (Haven't started using J8 yet.) I think a lot of the security issues come from non-defensive programming. Java makes it waaaaaay too easy to do things the wrong way. It should break a little more often than it does.

If security's a big concern, though, C# and Ruby/Rails are good options, too. Hell, if you know Java, C# takes about five minutes to get started in. Now when you start fiddling with LINQ and ASP.NET. . . .

I'd say Java's biggest flaw is how it covers up memory management. When you program in C or C++, you have to be more attentive to how much memory you're using. You get to understand exactly how memory + data flows through use of pointers. With Java, it just does that for you. You could go your entire programming life with no idea how things work "under the hood", because Java (or high level languages in general) hides that from you.

Re: Java

By the way, in some of OS which don't have a calculator utility, java can be used as a calculator.
I don't know about other programming languages, so I don't write them down.

Although, when I do a mistake and click "compile", the java sometimes shows me a message which is barely understood!!!

Re: Java

You've got to learn to understand what the compiler spits out at you. Usually the first 3 - 5 lines have the most immediately important information. (Not that the rest isn't important, it's just you've gotta start somewhere.)
