Java ThreadGroup: Manage and Organize Your Threads
ThreadGroup in Java is a class that provides a way to manage and organize threads as a single unit. It can be used to group threads that are related or share common resources. ThreadGroup allows you to control, monitor, and manage threads as a group, rather than individually.
In this example, a ThreadGroup named "WG" is created to manage a group of 5 worker threads. Each worker thread performs a simple calculation (random number multiplication) and prints the result. The main thread waits for all worker threads to finish before printing "All workers have finished."
