language Java detailed walk-through of the code for better understanding thank you.

Now as an individual task write a full full C++/ Java/JavaScript/VB/C# program that implements a Quicksort algorithm, and computes the length of time it takes to execute based on the different sample input size provided. At the end provide an empirical analysis of the findings. You will be evaluated as short Sample Input to the list Input # 1: "5 1 4 2 8" (say up to 50 items] Input # 2: 12, 45, 33, 72, 19, 08, 49, 98 [say up to 100 items] Input #3 : 1,2,3,24, 19,7,28,47,9. ( say up to 1000 items ]
