Bagaimana untuk mengganggu thread yang sedang berjalan di Java?

Sesuatu benang boleh mengganggu benang dengan menghantar isyarat sampukan dengan memanggil kaedah interrupt() objek benang. Ini bermakna gangguan benang disebabkan oleh urutan lain yang memanggil kaedah interrupt(). Kelas

Thread menyediakan tiga kaedah gangguan:

• void interrupt() - mengganggu thread.
• boolean statik terganggu() - Menguji sama ada rangkaian semasa terganggu.
• boolean isInterrupted() - Menguji sama ada benang terganggu.

Contoh

public class ThreadInterruptTest {
   public static void main(String[] args) {
      System.out.println("Thread main started");
      final Task task = new Task();
      final Thread thread = new Thread(task);
      thread.start();
      thread.interrupt(); // calling interrupt()<strong> </strong>method
      System.out.println("Main Thread finished");
   }
}
class Task implements Runnable {
   @Override
   public void run() {
      for (int i = 0; i < 5; i++) {
         System.out.println("[" + Thread.currentThread().getName() + "] Message " + i);
         if(Thread.interrupted()) {
            System.out.println("This thread was interruped by someone calling this Thread.interrupt()");
            System.out.println("Cancelling task running in thread " + Thread.currentThread().getName());
            System.out.println("After Thread.interrupted() call, JVM reset the interrupted value to: " + Thread.interrupted());
            break;
         }
      }
   }
}

Output

Thread main started
Main Thread finished
[Thread-0] Message 0
This thread was interruped by someone calling this Thread.interrupt()
Cancelling task running in thread Thread-0
After Thread.interrupted() call, JVM reset the interrupted value to: false
