示例
class NewThread extends Thread
{
NewThread(String threadname, ThreadGroup tg)
{
super(tg, threadname);
}
public void run()
{
for (int i = 0; i < 10; i++)
{
try
{
Thread.sleep(10);
}
catch (InterruptedException ex)
{
System.out.println(Thread.currentThread().getName()
+ " interrupted");
}
}
System.out.println(Thread.currentThread().getName() +
" completed executing");
}
}
public class ThreadGroupInterruptExp
{
public static void main(String arg[]) throws InterruptedException,
SecurityException
{
// creating the thread group
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(t1.getName() + " starts");
t1.start();
// interrupting thread group
tg1.interrupt();
// creating another thread
NewThread t2 = new NewThread("Thread-2", tg1);
System.out.println(t2.getName() + " starts");
t2.start();
}
}
输出:
Thread-1 starts
Thread-2 starts
Thread-1 interrupted
Thread-1 completed executing
Thread-2 completed executing
