• Deadlocks can occur in any concurrent system where processes
wait for each other and a cyclic chain can arise with each process
waiting for the next one in the chain.
• More specifically, deadlocks can occur in any system that satisfies
the four Coffman conditions (due to E. G. Coffman in 1971):
1. Mutual Exclusion Condition: a resource is either assigned to
one process or it is available
2. Hold and Wait Condition: processes already holding resources
may request new resources
3. No Preemption Condition: only a process holding a resource
may release it
4. Circular Wait Condition: two or more processes form a circular
chain where each process requests a resource that the next process in the chain holds
• Concurrent Java programs may satisfy these conditions, with the
object locks/monitors as the resources, so they may deadlock.
• We can avoid deadlocks by arranging our program so that one of
the Coffman conditions doesn't hold.
