Doing two tasks at the same time

[redfalcon]

Hi.

We are working on a project for school with the Mindstorms RCX and leJOS.
But we are currently confronted with a problem, and we can't seem to find a possibility to make two specific tasks run simultanously.
We want our roboter rotate for eight seconds (= 360 degree) and while doing that, we are trying to get a specific value from the light sensor. But how do you time these eight seconds? This would be possible with Threads, but it is not possible to download two Java-Classes to the RCX, isn't it?

You can create a program that uses multiple classes. The leJOS compiler will automatically compile and upload all the classes that the main class uses.

I guess you are using the Timingnavigator. You can use a SensorListner for getting the value of the light sensor if it exceeds a threshold value, without using threads.
