Specification for Profit/Loss Statement

Specification for Profit/Loss Statement -- versions 1, 2, 3, and 4

IDENTIFICATION:	XYZloss.java (where XYZ represents your initials)
PURPOSE:	Produce a profit/loss projection, and display the monthly information sorted in various ways.

Version 1

Using arrays initialized with test data, produce a report similar to the following:

Month	Sales	Revenues	Expenses	Profit (Loss)
January	100	200.00	1000.00	- 800.00
February	200	400.00	1500.00	-1100.00
March	400	800.00	2000.00	-1200.00
April	800	1600.00	2500.00	- 900.00
May	1600	3200.00	3000.00	200.00
June	3200	6400.00	3500.00	2900.00
...	...	...	...	...
December	4096	...	...	...

You will need arrays such as the following (They may be "global".):

String[] monthname
int[] sales
float[] revenues
float[] expenses
float[] profit // Initially empty; values will be calculated.

Set the price per item to $10.

Version 2

Produce a similar report, with rows rearranged from highest profit to lowest (i.e. greatest loss).
To do this, you must sort all the arrays, using profit as the "key" field.

Also produce a similar report showing all data, but with rows rearranged from highest to lowest expense amounts.
To do this, you must sort all the arrays, using expenses as the "key" field.

Finally, add another report report with the months listed in alphabetical order.

Versions 3 & 4

Remove the test data, and initialize the arrays based upon input values such as the following:

Price per unit sold. [price]
Price increase, after first 6 months. [priceInc]
Number of sales for first month. [sales1]
Percentage sales increase from month to month, for the first 6 months. [salesInc1]
Percentage sales increase from month to month, after first 6 months. [salesInc2]
Cost per item (first month). [cost]
Percentage increase in cost, month-to-month. [costIncrease]
Fixed expenses (for first month). [exp]
Percentage increase in fixed expenses, month-to-month. [expPct]

Additional dollar amount of increase in fixed expenses, month-to-month (in dollars) . [expIncr]

 
		//// Some of your code might look similar to the following:

		// Compute fixed expenses for this month.
		exp[j] = exp[j-1]  * (1.0 + expPct/100. )  +  (expIncr)

		// Compute sales volume for this month.
		pct= salesInc1 OR salesInc2 (depending on which month).
		sales[j] = sales[j-1]  * (1.0 + pct/100. )
