对相同性质的线程进行分组
Runnable runnable // = ...;
ThreadGroup userGroup = new ThreadGroup("user");
Thread userTask1 = new Thread(userGroup, runnable, "user-task1");
Thread userTask2 = new Thread(userGroup, runnable, "user-task2");
userTask1.start();
userTask2.start();
System.out.println("线程组活跃线程数：" + userGroup.activeCount());
userGroup.list();
线程组还能统一设置组内所有线程的最高优先级，线程单独设置的优先级不会高于线程组设置的最大优先级userGroup.setMaxPriority(Thread.MIN_PRIORITY);
停止线程组内线程不推荐使用stop，使用userGroup.interrupt();中断线程组内的所有线程
