The need for speed: coding styles for mobile devices

The very mention of the words "mobile application " one almost always thinks of "Java". Just about every mobile phone that is currently produced has a Java Virtual Machine as standard. Object Orientation is one of the key features of Java language. Is Object Orientation under the mobile environment more of a hinderance than a help? How does an Object Orientated solution compare to a more structured approach. How does the constant need for call methods compare with the Mining of the method functions themselves. How much of an advantage is Fixed Point Integer notation over double or floating point values in terms of computation speed and accuracy. These are some of the questions we wish to answer, by giving practical results from the domain of fractal generation.
