kchanger.java

通过线程控制来打印出julia集

public class KChanger implements Runnable {
	double r, i;

	Complex k;

	KChanger(Complex K) {
		k = K;
	}

	public void run() {
		while (true) {
			try {
				Thread.sleep(JuliaFrame.KDELAY);
			} catch (InterruptedException e) {
			}
			r = Math.random() * 4 - 2;			//range from -2 to 2
			i = Math.random() * 3.2 - 1.6;		//range from -1.6 to 1.6
			k.set(r, i);						//set the new value
			JuliaFrame.drawK(r, i);				//redraw
		}
	}
}
