The code has some unit tests that validate the logic.
There are also some classes with main function in them that output information to console. You can call them in the following way:
mvn exec:java -Dexec.mainClass="ua.yet.adv.java.concurrency.OperationsDeadlock"mvn exec:java -Dexec.mainClass="ua.yet.adv.java.concurrency.OperationsService"mvn exec:java -Dexec.mainClass="ua.yet.adv.java.concurrency.OperationsCompletableFuture"mvn exec:java -Dexec.mainClass="ua.yet.adv.java.concurrency.OperationsSemaphore"mvn exec:java -Dexec.mainClass="ua.yet.adv.java.concurrency.OperationsSynchronizers"
