Well I run this program on my m/c I got output according to the expectaions. I am giving here output on my m/c

Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]
Thread[thread two,10,main]
Thread[thread three,5,main]
Thread[thread one,1,main]

Well I think it's according to your expectations, what you was expecting could you let me know.....

according to your code..

th2.setPriority(Thread.MAX_PRIORITY);
th1.setPriority(Thread.MIN_PRIORITY);
th3.setPriority(Thread.NORM_PRIORITY);

th2 is with MAX_PRIORITY
th3 is then and at last is
th1

While a thread sleeps, other threads are allowed to execute. Priority only comes into play when two threads try to do something at the same time, which is not guaranteed to happen at all for our example.

Moving to our threads forum...
