ThreadGroup类的stop()方法用于停止线程组中的所有线程。
语法
public final void stop()
返回
此方法不返回任何值。
异常
SecurityException：如果不允许当前线程访问线程组或线程组中的任何线程，则抛出此异常。
示例
class NewThread extends Thread
{
NewThread(String threadname, ThreadGroup tg)
{
super(tg, threadname);
}
public void run()
{
for(int i = 0;i < 10;i++)
{
i++;
}
System.out.println(Thread.currentThread().getName() + " completed executing");
}
}
public class ThreadGroupStopExp
{
public static void main(String arg[]) throws InterruptedException,
SecurityException, Exception
{
// creating the threadGroup
ThreadGroup tg1 = new ThreadGroup("Parent thread");
ThreadGroup tg2 = new ThreadGroup(tg1, "Child thread");
// creating a thread
NewThread t1 = new NewThread("Thread-1", tg1);
System.out.println("Starting of Thread-1");
t1.start();
// creating another thread
NewThread t2 = new NewThread("Thread-2", tg2);
System.out.println("Starting of Thread-2");
t2.start();
// this will stop all the thread
tg1.stop();
}
}
执行上面示例代码，得到以下结果：
Starting of Thread-1
Starting of Thread-2
