每當我們想通過調用Java 中Thread 類的stop() 方法來停止線程的運行狀態時。該方法會停止正在運行的線程的執行，并將其從等待線程池中移除并收集垃圾。當線程到達其方法的末尾時，它也會自動進入死狀態。由于 線程安全問題，Java中不推薦使用 stop()方法。

句法

@Deprecated
public final void stop()

例子

import static java.lang.Thread.currentThread;
public class ThreadStopTest {
   public static void main(String args[]) throws InterruptedException {
      UserThread userThread = new UserThread();
      Thread thread = new Thread(userThread, "T1");
      thread.start();
      System.out.println(currentThread().getName() + " is stopping user thread");
      userThread.stop();
      Thread.sleep(2000);
      System.out.println(currentThread().getName() + " is finished now");
   }
}
class UserThread implements Runnable {
   private volatile boolean exit = false;
   public void run() {
      while(!exit) {
         System.out.println("The user thread is running");
      }
      System.out.println("The user thread is now stopped");
   }
   public void stop() {
      exit = true;
   }
}

輸出

main is stopping user thread
The user thread is running
The user thread is now stopped
main is finished now
