Top 10 Udemy Courses You can Buy in Black Friday and Cyber Monday Sale

Hello guys, Udemy is running the biggest sale of the year. It's actually a good time to buy some quality courses as you won't get another chance to buy the course at a price as low as $9.9 but the big question which courses should you buy?

I generally buy a lot of courses in Udemy sales and then access them whenever I need them. Though, I must warn you Udemy is addictive and I often buy more courses than I need, so beware of that and buy courses which you need now or in near future.

Even though both Thread and Executor, both are used to execute some code in parallel, there are some key differences between them. The main difference between a Thread and an Executor in Java is that it later provides a thread pool in Java. Along with several concurrency utilities like CountDownLatch, CyclicBarrier, Semaphore, FutureTask, Callable interface, and Conditions, JDK 5 also introduced a built-in thread pool, which provides a set of working threads to run your code in parallel. Since creating, starting, and running a thread is a time-consuming and expensive operation, many Java applications create a spool of thread at start-up and leverage that for executing the task in parallel until Java introduced the built-in thread pool.
