How can we use AtomicInteger for limited sequence generation say the sequence number has to be between 1 to 60. Once the sequece reaches 60 it has to start again from 1. I wrote this code though not quite sure wether this is thread safe or not?

public int getNextValue()
{
 int v;
 do
 {
   v = val.get();
   if ( v == 60)
   {
    val.set(1);
   }
 }
  while (!val.compareAndSet(v , v + 1));
   return v + 1;
  }
