Here is another online programming textbook from Princeton, Introduction to Programming in Java. It teaches the classic elements of programming, using an "objects-in-the-middle" approach that emphasizes data abstraction. The author uses specific applications, taken from fields ranging from materials science to genomics to astrophysics to internet commerce, to teach and demonstrate the programming concepts and techniques presented. Also available are hundreds of easily downloadable Java programs and real-world data sets.


Chapter 1: Elements of Programming
introduces variables; assignment statements; built-in types of data; conditionals and loops; arrays; and input/output, including graphics and sound.

Chapter 2: Functions
introduces modular programming. We stress the fundamental idea of dividing a program into components that can be independently debugged, maintained, and reused.

Chapter 3: Object-Oriented Programming
introduces data abstraction. We emphasize the concept of a data type and its implementation using Java's class mechanism.

Chapter 4: Algorithms and Data Structures
introduces classical algorithms for sorting and searching, and fundamental data structures, including stacks, queues, and symbol tables.

To get started.
Here are instructions for installing a Java programming environment on your Mac OS X, Windows, or Linux computer.

Full programming model.
Also provided are I/O libraries for reading and writing text and binary data, drawing graphics, and producing sound.

Prototype 1.6.0.2 Cheat Sheet
A long awaited Prototype cheat sheet – a full reference to a bleeding edge 1.6.0.2 is finally here. * Modules are sorted in a somewhat logical order – those commonly used are mostly in the left/center area, while deprecated/utility methods are all the way to the right Method can be recognized by parentheses following it (anything that doesn’t have ones is a property), Deprecated items are marked red and have NO parentheses/arguments specified, Prototype extends quite few native objects’ prototypes with a set of convenient methods. In such cases there’s an explicit note about it next to a module name – i.g. stripScripts() method from “String (String.prototype)” can be called as ‘foo’.stripScripts(), When a module is also a class, there’s a “(constructor)” note next to it – i.g. “Hash (constructor)” means that it should be called as new Hash(), There are few bonus items (such as those from Prototype.Browser) which are not yet included in documentation

Here is an online mobile programming course: Programming for the Android Platform, Developing Wireless Mobile Applications. The goal of this Android programming tutorial course is to teach the technical aspects of how to program Android devices and use the Andoid API, with particular emphasis on scientific and educational applications. This platform is literally booming at this time as more than 300,000 new Android smartphones are activated per day.

Unlike the iPhone, Android is designed to run on many devices produced by many hardware manufacturers, and is based on free, open-source resources. It is programmed with a combination of Java and XML. One can develop programs on an emulator running on a regular computer, so it isn't even necessary to have an Android device to begin writing programs. There is a powerful and very well documented Software Development Kit (SDK) that is freely available, a comprehensive Interactive Development Environment (IDE) called Eclipse with an Android plugin that is free, and the Java and XML (with their editors, compilers, and interpreters) with which one programs Android devices are also free.
