Java-Beispiele - Thread-Priorität anzeigen
Java-BeispieleDas folgende Beispiel zeigt, wie man die Methode getThreadId() verwendet, um die Thread-ID abzurufen:
Main.java-Datei
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() - Priorität="
+ 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());
}
}
Die Ausgabe des obigen Codes ist:
in main() - Thread.currentThread().getPriority()=5 in main() - Thread.currentThread().getName()=main in run() - priority=5, name=threadA in run() - priority=5, name=threadA in main() - threadA.getPriority()=5 in run() - priority=5, name=threadA in run() - priority=5, name=threadA in run() - priority=5, name=threadAAndere Erweiterungen
