Question

I am very curious to know how to implement the Ctrl+K (code sample) feature against code,
For example:

public static void main(String args[]){
  System.out.println.out("welcome");
}

That will be nicely formatted?

1. Do we require any package to implement this?
2. Any ready made code available to do this?

Can any one help me with this? I am planning to develop a site where this feature would be a real helpful.
