1.11 Daemon Threads

There are 2 threads in Java, 1 are daemon threads, 1 are non-daemon threads

A daemon thread is a special thread that, when a non-daemon thread is present in the thread, is automatically destroyed by the daemon thread, and the typical daemon thread is the garbage collection thread.

Test as follows

1  PackageCom.cky.daemon;2 3 /**4 * Created by Edison on 2017/12/3.5  */6  Public classMythreadsextendsthread{7     Private intI=0;8 9 @OverrideTen      Public voidrun () { One         Super.
