Would someone be able to help me please if you could give me the java code along with the chart that is needed i would greatly appreciate that thank you.

Perform an experimental analysis to test the hypothesis that Javas Array.sort method runs in O(nlogn) time on average. You should try several runs over many different problem sizes (at least 5 input sizes, input size should be greater than 50). Attach your code along with screenshots here. Draw a chart showing the running time against the input size.
