Daemon Thread Concept Simplified in Java



Daemon threads are service threads. Their main objective is to provide different services to other thread.They normally runs in an infinite loop and attain client thread's requesting service when no other thread is present or exists.The Daemon thread automatically exists.JVM does not wait for the death or destroy of Daemon thread before concluding a program.
Here is the code to create a Daemon thread

Thread t=new Thread();
//creates a new thread
t.setDaemon(true);
//mark the thread as daemon thread
 
By default,all threads created by Daemon thread are also Daemon thread.
