Advanced Algorithm Analysis（ random-number-generator ）

I am using the development platform IDE：Visual Studio.I need programming language is Java.I need all running code and text file (*.txt). A) Task 1 - Implementation and performance analysis of computation algorithms For the first part , you are required to develop 2 functions : a) A random-number-generator function, that generates and returns a series of random numbers b) A save-to-file function to save a set of random numbers into a simple text (*.txt) file (which could later be opened by simple text editor like Microsoft Notepad / Wordpad) B) Task 2 - Implementation and performance analysis of sorting algorithms For this task, you are to implement 2 sorting algorithms: insertion sort and quick sort which will take in a array of values, and proceed to sort them in ASCENDING order. a) The sorting functions should be implemented using the same programming language as Task 1. b) Please make use of your random-number-generator function (implemented for Task 1)to generate random whole number values as inputs to each of your sorting function ([login to view URL] and quick sort ) c) Please make use of your save-to-file function (implemented for Task 1) to store the sorting results (i.e. sorted numbers) for each of your sorting function d) Design various test scenarios, to test each sort function with different sizes of input (n).
