Subject: Thread applet
Hi all... I make this thread applet to draw a
chart so that everytime the data changes, the chart changes automatically.
I have implement the Runnable for the applet and
here's the code for
start(), run(), stop(), and init() ... can
anybody tell me what's wrong?
public class chartApplet extends Applet
implements Runnable {
Thread thread = null;
void drawChart() {
}
public void start()
{
if (thread==null){
thread = new
Thread(this);
thread.start();
}
}
public void stop() {
if (thread!=null){
thread.stop();
thread=null;
}
}
public void run() {
while (thread!=null) {
try
{thread.sleep(1000*60);}
catch
(InterruptedException e){};
drawChart();
}
}
public void init() {
now =
System.currentTimeMillis();
setLayout(new
GridLayout(1,1));
drawChart();
}
}
