What is the difference between a daemon thread and a normal thread, the method Setdaemon (true) that invokes the thread object before the thread is started can be set as a daemon thread.

Daemon threads use less, but are not useless, for example, the JVM's garbage collection, memory management, and other threads are daemon threads. There is in the database application, the use of the database connection pool, the connection pool itself contains a lot of background threads, monitoring the number of connections, time-out, status, and so on.
