How to calculate EXECUTION TIME in Java! ⏱️

How to calculate execution time of a program tutorial example explained

This can be a helpful way to find the execution time if the Big O notation is somewhere between a best case and worst case.

For example: A user can adjust the clock during execution, even to a past date, and this would give you negative time.
