Error creating an instance of a runnable thread

Question

I'm trying to create two instances of a runnable thread but get this error message (in Eclipse):
"No enclosing instance of type GE4000 is accessible. Must qualify the allocation with an enclosing instance of type GE4000 (e.g. x.new A() where x is an instance of GE4000)."
I don't understand this error at all.
GE4000 is GE4000.java
The error occurs here and is within a protected static boolean method.
for(int t = 0; t < (int) cameraCount; ++t) {
               streamThreads[t] = new Thread(new CaptureStream(cameraHandle[t], frameBuffers[t], frameCount, basePath));
CaptureStream Class is defined:
     public class CaptureStream implements Runnable {
the constructor is:
     CaptureStream(Pv.tHandle handle, Pv.tFrame[] cameraFrames, int frameCount, String basePath) {
Ironically, within CaptureScreen's run method I do an analogous creation of another thread without seeing an error.
Edited: I un-nested it and it works! Thanks

I'd recommend avoiding using inner classes or at least learning how to use them before actually using them.I'm new at Java and that's why I posted to the forum.
Or do you really need to have CaptureStream as an inner class?
In any case you're trying to create one in a static method, where no enclosing instance of the outer class (GE4000) is available. So at the very least you'd need to make it a static nested class.OK, this is my structure:
public class GE4000 {
class CaptureStream implements Runnable {
run() {}
boolean startStreamCapture() {}
     public static void main(String[] args) {
startStreamCapture();
The method startStreamCapture was static and when I made it to non-static the error went away.
However I can't use the method in main because it's not static.
Do I understand correctly that the way to solve this is to put class CaptureStream into CaptureStream.java? That is, un-encapsulate it and then make startStream static?
BTW My original version extended Thread and it compiled (but didn't do what I wanted) the error cropped up when I changed it to implement runnable.
I appreciate your help.
