Everything matters when it delivered on time, so why not the same rule applies for your programming unless you are developing a system for turtles.
Getting the execution time of a bunch of methods together in one line will not give you an accurate time. You can execute each method in Java runnable class to measure the elapsed time of each and every method with the identification name.
The below method is a demonstration of getting elapsed time of “myMethod()” by executing the method inside a runnable interface into “ProfileTime.exec()” static method.
Copy the ProfileTime class into your project and start profiling your application right now.
Have you done it already? I mean push-ups if not start it from today.
