Learn how to create and manage threads by extending the thread class, with practical examples and discussion on running and extending thread behavior.

Explore Java object-oriented programming by examining getName(), getId(), getPriority(), setPriority(3), getState(), MIN_PRIORITY, and NORM_PRI, with practical examples of main thread behavior.
