Does it harm if I send many interrupt to non-sleeping Thread

I have a thread that I make it sleep (using Thread.sleep(60000) ) for some time when waiting for some task to execute. Once there a request arrived, I wake it up from another thread by calling (t.inerrupt).

I can see it it works fine so far. If I send t.inerrupt when Thread in a sleep, it wake up. However, what if the process is not sleeping (doing actual work), would calling t.inerrupt have any effect on the thread?

Read the javadoc

If none of the previous conditions hold [ie. thread is not blocked or sleeping] then this thread's interrupt status will be set.

So only a flag is set.
