我们如何在Java中停止线程？
每当我们想通过调用Java中的Thread 类的stop() 方法来停止线程的运行状态时，该方法将停止执行线程并从等待的线程池中将其删除并收集垃圾。当线程到达其方法的末尾时，它还将自动移动到死状态。将停止()方法被弃用 Java中由于 线程安全的问题。
语法
@Deprecated public final void stop()
示例
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;
}
}输出结果
main is stopping user thread The user thread is running The user thread is now stopped main is finished now
