通过线程控制来打印出julia集

public class DataGenerator implements Runnable {
	int imageWidth, imageHeight, color;

	DataPacket p;

	DataBuffer inputBuffer;

	DataGenerator(int imageWidth, int imageHeight, DataBuffer inputBuffer) {
		this.imageWidth = imageWidth;

	}

	public void run() {
		while (true) {

			p = new DataPacket((int) (imageWidth * Math.random()),	
					(int) (imageHeight * Math.random()), color);
						//chooses a pair of random coordinate swith in the image area
			inputBuffer.put(p);			//put this packet to inputBuffer
			try {
				Thread.sleep(5);
