  What does super.clone() do?

Object class has a protected clone() method declared to make it possible for all classes make a clone of itself when needed. The clone() is often used when a new instance of the class is needed while at the same time to maintain the same state as the original object. Any class which wants to have clone enabled has to implement the marker interface Cloneable. If a class which implements Cloneable doesn't override the Object.clone() method, the Object.clone() method will be called to just make a b...

This is as good a place as any, and hopefully it will be useful to others.I needed to make an Ajax call, so I turned to my good friend XMLHttpRequest.

Next are some tips for writing highly efficient PHP codes. They are described below: 0. Use single quote to replace double quote, this will be better since PHP will serach for variables in double quoted strings. Note, only echo can do this; 1. If we can define methods of a class as static, then do it. It will increase access speed by 4 times; 2. $row["id"] is 7 times faster than $row[id]; 3. echo is faster than print, and also use echo's multiple parameter format such as echo $str1,$str2 inst...
