Why should anybody learn Objective-C if already know Java?

It's all about what language is best supported in the environment.[/quote wrote:
Please point/post what about Java isn't supported and what is best supported in Objective-C than Java.

What performance benefits of being native? People don't do enough computation in IOS apps to care about performance of the app, its all about the performance of the frameworks, and you can't change that.
The point is that writing for IOS essentially requires you to write in Objective-C. These days, the best way for an independent to have a profitable product is to sell it through the app-store, which means writing Objective-C.
The good reason is that when you write in Objective-C, you get, for free, or at least no cost to use, a very rich framework that gives your app the native look and feel, and all the cool multi-touch support, etc. Java is cursed/blessed with being platform independent, so you only get to use the minimal common subset of features on all platforms. THis means that Java is way behind IOS on cool touch and sensor apps.
We are talking about iOS devices right? There isn't a much ram or cpu power on these devices? When you do a lot of animations you really should go for C in opengl.

Good one... PROFIT!

Another one.. "Native look and feel" and "Multi-Touch Support".
What else guys?

Whether it is can be called Java or not, but does your last line applies on Java's Android?

Java as a cross-platform product, sure, its cursed with minimal common subset. Nothing prevents a vendor such as Google from releasing a library that works great on a specific set of hardware. But that doesn't mean that Swing or AWT has any modern UI support.
Which gets back to what is Objective-C really? and what is Java?
The modern interest in Objective C is for IOS development. Its really Objective-C plus the Apple supplied frameworks for their hardware.
While I'm sure someone could, in theory, write Objective-C for Android, I've never heard of anyone doing that. For Android, you write in Java with the Dalvik world. Or for the Dalvik world. I believe that Google is being sued over whether or not you write in Java for Dalvik.
honestly, I don't even know how to answer that question, but I'll try:
It's like asking "Why should I bother learning German if I already know English?" Maybe you want to talk to people in Germany, Austria and Switzerland? Maybe you want to order a meal at a restaurant there? Maybe you want to move there or open a business?
Just as learning new spoken languages is either useful or necessary, depending on what you want to or have to do, so is learning new programming languages.
You want to use Ruby on Rails? Well, you'll need to learn Ruby because Rails happens to be written in Ruby.
You want to use SproutCore or jQuery? Well, you'll need to learn JavaScript.
You want to develop for the Mac or iOS? Well, you'll need to learn Objective-C because all of the Cocoa frameworks are written in Obj-C (or C).
So, to sum it up: You don't have to learn Obj-C if you don't want to develop for iOS. If you want to stick with Java, you should check out Android. But if you do want to develop for iOS, you have to learn Obj-C (unless you use something like Titanium or make HTML5 apps, but then you'll have to learn JavaScript
).
