Daemon thread : It is a service provider thread that provides services to the user
thread. Its life depend on the mercy of user threads i.e. when all the user
threads dies, JVM terminates this thread automatically.
It provides services to user threads for background supporting tasks. It has no role in life than to serve user threads.
Its life depends on user threads.
It is a low priority thread.
There are many java daemon threads running automatically e.g. gc,
finalizer etc.
Note: It provides services to user threads for background supporting tasks. It has no role in life than to serve user threads.
Its life depends on user threads.
It is a low priority thread.
Advantage: The main
purpose of the daemon thread is that it provides services to user thread for
background supporting task. If there is no user thread, why should JVM keep
running this thread. That is why JVM terminates the daemon thread if there is
no user thread.
