Question about the task Monitoring thread state
Java Multithreading, Level 5, Lesson 5
Resolved
Please help For some reason instead of only displaying the state once, it continually displays it whilst it's running. It also does not display "TERMINATED". Is this because I setDeamon to true, and so it shuts down as soon as the other Thread stops?
