可能重复:
关于为非守护线程提供某些服务的守护线程
我想开发一个应用程序,其中守护线程将为非守护线程提供服务,我开发了以下代码
import java.util.concurrent.Executors;
import java.util.concurrent.ThreadFactory;
public class daemonTest {
public static void main(String... a) throws Exception {
ExecutorService service = Executors
.newSingleThreadExecutor(new ThreadFactory() { // anonmyous class start
public Thread newThread(Runnable r) {
Thread two = new Thread(r, "two");
two.setDaemon(true);
System.out.println("two --->" + two.isDaemon());
return two;
}
});
for (int i = 0; i < 10; i++)
service.submit(new Runnable() {
@Override
public void run() {
System.out.println("[" + Thread.currentThread().getName()
+ "] - Hello World.");
Thread.yield();
}
});
service.shutdown();
}
}
但是请告知如果我创建一个不是守护线程的新线程,那么名为两个的守护线程将如何为新创建的线程提供服务,最后我想要实现
