Daemon Threads in Java

Submitted by heartin on Wed, 10/14/2015 - 20:59

A daemon thread is a background thread and dies when the thread that created it ends.

A thread that is not daemon is called a user thread.

We can make a thread as daemon thread by calling setDaemon (true) on the thread instance.

We can call setDaemon() for a thread only before it starts, else an IllegalThreadStateException will be thrown.

 

Example:

MyThread t1= new MyThread ();

t1.setDaemon(true);

t1.start(); 

 

Note: A complete working example will be added soon.
