Non-static nested classes are called inner classes. Static class can be defined as : class OuterClass{ static class StaticNestedClass{ //OTHER STUFF } } Static nested classes are accessed using the enclosing class name: OuterClass.StaticNestedClass For example, to create an object for the static nested class, use this synta...

  An open letter to those who want to start programming

First off, welcome to the fraternity. There aren’t too many people who want to create stuff and solve problems. You are a hacker. You are one of those who wants to do something interesting. “When you don’t create things, you become defined by your tastes rather than ability." – WhyTheLuckyStiff Take the words below with a pinch of salt.

  Eleven Equations True Computer Science Geeks Should (at Least Pretend to) Know

This idea is a complete rip off an article that appeared in Wired a little while ago and it got me thinking what would my list for Computer Science look like?  Plus I thought it might be a fun post and unlike the Wired list this one goes to eleven.  So here they are in no particular order: Binomial Coefficient The Binomial Coefficient equation generates Pascal’s Triangle and gives you the coefficients for the Binomial Theorem these ideas are often attributed to Pa...

  What is Asian UI design like from a Western point of view?

From a western point view, Asian UI designs are usually quite dense and compact. People in Asia are think more in detail when they start design something. They think these designs have following characteristics Dense tightly packed text Tiny low-quality images More columns than you can count Bright clashing colours and flashing banners Overuse of outdated technologies like Flash While the Western design is much simpler.

  NIO vs IO in Java

Java 1.4 provides a new API for handling IO -- NIO. This is a non-blocking and buffer oriented IO API. Below are main differences between the NIO and IO in Java. IO NIO Stream oriented Buffer oriented Blocking IO Non-blocking IO N/A Using selector Stream oriented vs Buffer oriented The main difference is that IO is stream oriented where the data is read byte by byte and the data will not be buffered normally.This means there is no pointer to move forward and backward in the stream. I...

  Behavior of defer function in named return function

In Go, there is a special concept of named return value in function where a returned value can have name. For example, below is a named function in Go. func returnNamed() (i int) { i = 1 return } When the function returns, the return value i will have a value of 1.  Also, Go has a concept of defer which will execute a function just before the calling function exits. This is similar to what finally block does in other languages such as Java. For example, a defer function can be func deferF...

  The Value of the Designer Who Codes

"Well, it's a start, but basically it stinks," said Steve Jobs, telling early Apple engineer Chris Espinosa exactly how he felt about the company's first calculator application. Iteration after iteration, Jobs continued to be dissatisfied with the calculator. Espinosa continued to code, slowly inching his way to perfection. But nothing was quite right. In a flash of both brilliance and perhaps frustration, Espinosa put together a visual builder that let Jobs design the calculator himself...
