how to restart a Thread?
- by wizztjh
It is a RMI Server object , so many sethumanActivity() might be run , how do i make sure the previous changeToFalse thread will be stop or halt before the new changeToFalse run? t. interrupt ?
Basically when sethumanActivity() is invoke , the humanActivity will be set to true , but a thread will be run to set it back to false. But I am thinking for how to disable or kill the thread when another sethumanActivity() invoked?
public class VitaminDEngine implements VitaminD {
public boolean humanActivity = false;
changeToFalse cf = new changeToFalse();
Thread t = new Thread(cf);
private class changeToFalse implements Runnable{
@Override
public void run() {
try {
Thread.sleep(4000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
humanActivity = false;
}
}
@Override
public void sethumanActivity() throws RemoteException {
// TODO Auto-generated method stub
humanActivity = true;
t.start();
}
public boolean gethumanActivity() throws RemoteException {
// TODO Auto-generated method stub
return humanActivity;
}
}
Edited after the help of SOer
package smartOfficeJava;
import java.rmi.RemoteException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class VitaminDEngine implements VitaminD {
public volatile boolean humanActivity = false;
changeToFalse cf = new changeToFalse();
ExecutorService service = Executors.newSingleThreadExecutor();
private class changeToFalse implements Runnable{
@Override
public void run() {
try {
Thread.sleep(4000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
humanActivity = false;
}
}
@Override
public synchronized void sethumanActivity() throws RemoteException {
humanActivity = true;
service.submit(cf);
}
public synchronized boolean gethumanActivity() throws RemoteException {
return humanActivity;
}
}
