Descriere
In cadrul acestui training abordam elementele de baza ale Java Multithreading API. Ne uitam la sintaxa si clasele cheie si te invatam cum sa rulezi cod intr-un thread separat, cum sa sincronizezi accesul la resurse comune intr-un multithreaded environment, cum sa folosesti monitor, cum sa implementezi thread execution si multe altele.Acest curs face parte dintr-o serie de 3 dedicate multithreading. Celelalte doua trining-uri abordeaza java.util.concurrent package si asynchronous programming and ForkJoin Framework.
