BasicThreadProgram.java

/*
In this program we executed two for loops simultaneously with the help of thread
We created thread here by extending Thread class.

Life cycle of threads
1. New : Thread is crated but not yet started.
2. Runnable : Start method got exectucted and it is before thread scheduler select it.
3. Running : Afte thread scheduler has selected it.
4. Not runnable : Thread alive, not eligible to run.
5. Terminated : Thread got terminate.
