Hi All,
I want to know what is Daemon Thread and how it is different from
Non-Daemon Thread.

Thanks & Regards,

It's just a flag in the Thread object. The JVM will continue to run only as long as non-daemon threads exist. As soon as the only running threads have the daemon property set, the JVM will exit. That's it -- nothing more.

It is sorta covered in the JavaRanch Style Guide.
