public long lockRecord(long recNo)
throws RecordNotFoundException;
I don't understand these:
"the current thread gives up the CPU and consumes no CPU cycles until the record is unlocked."
if i write something like:
while(...){
wait();
}
can this "give up the CPU"??

Yes, wait() will give up the CPU until notify() or notifyAll() is called.
