Hi this question doesn't really concern WiiremoteJ. In the test application at the IRInputReceived im not sure what the : in the loop does.

for (IRLight light : evt.getIRLights())

Is it a logic operator?

I did it like this but your code is mush nicer so I want to understand it

Thx for answers!

light = new IRLight[4];
light = evt.getIRLights();
System.out.println("X:");
for(int i=0; i<4 && light[i] != null; i++){

System.out.println("X: "+light[i].getX());
System.out.println("Y: "+light[i].getY());
}

if i'm correct, his code means his iterating over the lights.

it is exactly what you do, instead light in his loop his equal to light[i] in your loop.
His way is much nicer

Hehe. Yep, as of Java 5, there's a nice new for-each loop. Just be careful using it with threading. It works by creating an Iterator and Iterators aren't thread-safe.

Ok thx!
So you dont have to define the length before starting the loop? Will it loop for every IRLight objekt found in the event and store it in light?

Have I understod this right?

[Cha0s]

Yep. It goes through each element in Iterable (that's an interface that means the thing can be iterated through. Arrays, ArrayLists, etc are all Iterable) and puts the value in light. Then you do something with it and it puts the next value in light, etc. until it goes through all the values in the Iterable.
