Using the getThreadGroup() Method of Thread

If you need to know which thread group a thread belongs to, you can use the getThreadGroup() method on Thread . To find out which thread group threadX belongs to, use this code:

ThreadGroup groupForThreadX = threadX.getThreadGroup();

groupForThreadX is a reference to the ThreadGroup that threadX belongs to. If a thread is no longer alive , getThreadGroup() returns null instead of a ThreadGroup .

To determine which thread group the thread executing a block of code belongs to, use:

ThreadGroup group = Thread.currentThread().getThreadGroup();
