I'm not quite sure what you are asking, but here are a couple of
possible answers - if neither fits, consider a more detailed question.

1. wait and notify can only be called in synchronized code. The wait
code should check that it is supposed to wait inside the same
synchronized block. The notify code should only change whatever controls
whether to wait inside the same synchronized block as the notify.

2. If you are using a current version of Java, check the
java.util.concurrent package. A lot of things that used to be done with
explicit wait-notify code can instead be done using concurrent queues,
barriers etc.
