When is it appropriate to split up complex computer programs and processes into smaller units, and how does this happen? Is it useful to analyze this system from a logical standpoint?

Write a complete java program that will store the weekly sales data for a small shop that sells candles into two dimensional array of type double, the shop has five candle scents as follow: week 1 sales week 2 sales week 3 sales week 4 sales Candle Scent 1 41.41 23.33 4.09 1.20 Candle Scent 2 33.86 22.30 27.85 17.35 Candle Scent 3 8.58 7.97 0.61 28.39 Candle Scent 4 10.23 32.62 22.21 21.91 Candle Scent 5 43.16 12.57 20.33 2.40 Your program should calculate and prints the followings: Total sa for week 1 Total sales for week 2 Total sales for week 3 Total sales for week 4 Maximum sales with the week number and candle scent number was found. Minimum sales with the week number and candle scent number was found. Sample run: Total Sales of Week 1 = 137.25 Total Sales of Week 2 = 98.80 Total Sales of Week 3 = 75.09 Total Sales of Week 4 = 71.26 Maximum Sales = 43.16 found week 1 for candle scent 5 Minimum Sales = 0.61 found in week 3 for candle scent 3

Does the Von Neumann Cycle make sense to you? To what extent do the central processing unit and main memory get involved at certain stages?

Is it advantageous to divide large-scale computer processes and programs into subsystems? Is there any benefit to rationally disassembling this system?
