I am studying java threads and deadlocks, I understand deadlock's examples but I wonder if there are general rules to follow to prevent it.
My question is if there are rules or tips that can be applied to the source code in java to prevent deadlocks? If yes, could you explain how to implement it?

The canonical technique for deadlock avoidance is to have a lock hierarchy. Make sure that all threads acquire locks or other resources in the same order. This avoids the deadlock scenario where thread 1 hold lock A and needs lock B while thread 2 holds lock B and needs lock A.
Deadlock in Java is a condition where two or more threads are blocked forever, waiting for each other. This usually happens when multiple threads need the same locks but obtain them in different orders. Multithreaded Programming in Java suffers from the deadlock situation because of the synchronized keyword.
Some quick tips out of my head
