Main Thread in Java

In Java programming, when a program begins the first thread that starts running is called main thread.

 Other threads(child thread) can be spawned from this main thread.

When program terminates, the main thread must be the last thread in the program to end. When the main thread stops, the program stops running.

Main thread is created automatically, but it can be controlled by the program by using a Thread object.
