Avoid setting thread priorities to control interactions between threads. Using the default thread priority should be sufficient for most applications.

However, if you need to enforce a specific synchronization order, use one of the following alternatives:

• Waiting for a notification using the wait and notifyAll methods
• Using the java.util.concurrent library

In some cases, calls to Thread.sleep may be appropriate to temporarily stop execution (provided that there is no possibility for race conditions), but this is not generally recommended.
