The javadoc for these 2 methods: ThreadGroup.enumerate(Thread[]) Vs ThreadGroup.enumerate(Thread[],boolean) seems to refer to the same thing. Both listing the active threads in the current thread group PLUS the active threads in subgroups of the current group. What are the difference between them?

By default, the ThreadGroup.enumerate(Thread[]) method copies all the active thread in this thread group and its subgroup. The other method can be used with the boolean value set to false when you need to copy only the active threads of this group and not its subgroup.

So, ThreadGroup.enumerate(Thread[] t) equivalent to ThreadGroup.enumerate(Thread[] t,true) ?

That's what the Javadocs imply, no? Seems like it'd be pretty simple to test empiracally as well.
 
So you made a portal in time and started grabbing people. This tiny ad thinks that's rude:
