Descriere
In acest training vei invata cum sa folosesti java.util.concurrent package. Vom analiza fiecare clasa in parte si iti vom arata cum sa le folosesti. Vein invata sa utilizezi synchronized collections, executors, atomics si multe altele.Acest curs face parte dintr-o serie de 3 dedicate multithreading. Celelalte doua trining-uri abordeaza Multithreading (threads, synchronization, monitors etc.) si asynchronous programming and ForkJoin Framework.
