Nice to meet you, my dear developers,I got some questions

[wjcking]

Firstly, Pleased to meet you, my friends.

I am a C# developer from China, having programming experience more than 3 years. Not so much, but I do acquire many skills

such as Web applications, windows applications, the use of classes, N-tier system, some design pattern and the like. In

addition, my review of data structures and algorithms is going on.

Now, I intend to study another programming language. Java, undoubtedly, is my tendency. As a new beginner,here I got some

questions for you, my friends.

1) Is there a shortcut or to learn Java depending on my C# experience.

2) Can we use Java to develop windows/linux desktop applications with beautiful shell (Microsoft WPF, so to speak)?

2) Apart from developing cellphone' games, what else things can Java develop on cellphones? (embeded software?)

3)Are there any examples related to 2D/3D programming with Java?

4)Can Java develop computer games (examples?), and is its efficiency better than Cpp?

5)In addition to Web, Cellphones and desktop app development, what else can Java do? some examples ?

6)Can we develop iphone programs by using Java?

7)Where can I get new Java information like Java7, JavaFx,which I mean websites or somethings?

Thanks a lot, while the internet can provide me relative information, I desire to hear YOUR opinions inner voice, my friends!!

Hi there, welcome on the forums.
I can not give an answer to all your questions, but i do believe that if you have 3 years experience in c#, you will master java prety fast. If you're familiar with the OO concepts , its just a matter of learning the new syntax so, this shouldnt be too hard.
I can also give an answer to you're 5th question: yes java can be used to develop computer games. I'm not an expert in this area or so, but it is possible, though not very often done.

Regards, steelshark

hi wjcking

for an answer to

7)Where can I get new Java information like Java7, JavaFx,which I mean websites or somethings?

look at Developer Resources for Java Technology there you will find a lot of information about java se, ee, me, fx and so on.

and for

2) Apart from developing cellphone' games, what else things can Java develop on cellphones? (embeded software?)

look for example Forum Nokia - Code Examples where you can find all kind of code examples for nokia devices.

and for

4)Can Java develop computer games (examples?), and is its efficiency better than Cpp?

look here Amazon.com: java games also in the reviews you can find a lot of comments relativ to your question above.

2) Can we use Java to develop windows/linux desktop applications with beautiful shell (Microsoft WPF, so to speak)?

Not even close in native java comparing to WPF.
You would have to use front end in Adobe Flex/AIR to make something look
nearly that good.

6)Can we develop iphone programs by using Java?

Instead of using native application development (written on objective C on Mac environment Cocoa fraework...) you can always use web approach.
You can use java servlet/JSP for back-end and choose you favorite
technology for front-end related to HTML, CSS, and JavaScript.
This 2 approaches are very different and you will hear many different opinions
about both at the moment.

Before you choose your approach
i would strongly suggest to read this short tutorial which will
help you make good decision:

Preface

And it's mobile platform war at the moment and many developers cannot choose which platform to work on:
Android, iPhone, BlackBerry, Symbian, Windows Mobile,
i think that crucial thing for you is to fugure out if you can kill 5 birds with 1 stone, because you don't want to spend million working hours on learning
each platform, one at the time. So can u manage to make a small web app that will run smoothly in mobile phone browser and use similar version of same app for regular PC users over Internet in regular browser...There are many other question here to solve...

You will find a lot of mobile phone emulator and simulator sowtware in Java
that comes as part of IDE (like NetBeans Mobility Pack) or as separate software so you can begin your development.
