检查线程的Java示例

public class Main extends Object {

   private static Runnable makeRunnable() {

      Runnable r = new Runnable() {

         public void run() {

            for (int i = 0; i < 5; i++) {

               Thread t = Thread.currentThread();

               System.out.println("in run() - priority = " + t.getPriority()+ ", name = " + t.getName());

               try {

                  Thread.sleep(2000);

               } catch (InterruptedException x) {}

            }

         }

      };

      return r;

   }

   public static void main(String[] args) {

      System.out.println(

         "in main() - Thread.currentThread(). getPriority()=" + Thread.currentThread().getPriority());

      System.out.println(

         "in main() - Thread.currentThread().getName()="+ Thread.currentThread().getName());



      Thread threadA = new Thread(makeRunnable(), "threadA");

      threadA.start();

      try {

         Thread.sleep(3000);

      } catch (InterruptedException x) {}

      System.out.println("in main() - threadA.getPriority() = " + threadA.getPriority());

   }

}
