I have taught myself a lot of Objective-C over the past year and a half, and have even been able to publish some iOS apps on the App Store. Concepts that were foreign to me before about object oriented programming are now second nature and I understand MVC, inheritance, polymorphism etc. I'm now interested in learning to develop for the Android platform, which will entail learning Java. I want to find resources that can match up Java basics with regards to syntax and structure with the same things from the Objective-C world.
The Wikipedia entry for Objective-C has exactly what I'm looking for with regards to how Objective-C relates to C++. If there is a document, blog post or book dedicated to something like this for Java in relation to Objective-C I would be all over it like a bear on honey. It should include things like
Thank you for all of your suggestions!

Objective-C is a compiled OO programming language. Java is both compiled and interpreted and therefore does not offer the same run-time performance as Objective-C. Objective-C features efficient, transparent Distributed Objects. Java features a less efficient and less transparent Remote Machine Interface.
Most programmers agree that Java is easier to learn first. Java's syntax is usually easier for new programmers to understand. The syntax requirements in C++ are very strict. It is difficult to write C++ in a readable way and making a single mistake can set off a chain of errors.
Most experts will tell you that Java is easier to learn. It's a newer language than C++ and isn't as complex in its principles or execution. However, there's more to consider than a language's learning curve. Selecting a programming language comes down to what you want to do with it.
Java is more data-oriented. C is a middle-level language because binding of the gaps takes place between machine level language and high-level languages. Java is a high-level language because translation of code takes place into machine language using compiler or interpreter.
"Matching up syntax" is not necessarily a useful thing. The two languages are not merely different syntaxes for the same thing. Lots of people go into a new language with that mindset, and it leads them to write bad code in their new language. For example, class methods in Objective-C are roughly equivalent to static methods in Java, but class methods can be overridden in subclasses while static methods can only be hidden by new static methods — they're more similar to namespaced functions than methods.
Better to just learn Java from a good book or tutorial — without your baggage from Objective-C.
