Java ThreadGroup stop()用法及代码示例

ThreadGroup 类的 stop() 方法用于停止线程组中的所有线程。

用法

public final void stop()

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();
    }
}

输出：

Starting of Thread-1
Starting of Thread-2
