Java Multithreading and Parallel Programming Masterclass - Daemon Threads and User Threads

The video tutorial explains the difference between user-level and daemon threads in Java. User-level threads are created by the user and must complete before the JVM exits, while daemon threads are low-priority and can be terminated by the JVM at any time. The tutorial includes an example of creating and running both types of threads, demonstrating their behavior. It also highlights a JVM API glitch where calling the join operation on a daemon thread blocks execution until the thread completes. The importance of careful design when using daemon threads is emphasized.

Describe a scenario where using a demon thread could lead to issues.

What is the effect of calling the join operation on a demon thread?

How should one design an application considering the use of demon threads?
