3. The documents produced by your script

JAVA program

 

a. Write a Java program that is reading from the keyboard a value between 111 and 900 and is printing on the screen the prime factors of the number.

Your program should use a cycle for validating the input (if the value typed from the keyboard is less than 111 or bigger than 900 to print an error and ask the user to input another value).

Also the program should print the prime factors in the order from smallest to biggest. 

For example,

for the value 128 the program should print 128=2*2*2*2*2*2*2 

for the value 122 the program should print: 122=2*61

b. change the program at a. to print one time a prime factor but provide the power of that factor:

for the value 128 the program should print 128=2^7

for the value 122 the program should print: 122=2^1*61^1

* PROJECT STEPS

1. Takara Hiyashi is on the board of the Green Lake Sports Camp, a recreational summer camp in Syracuse, New York. She is using an Excel workbook to analyze the camp’s financials and asks for your help in correcting errors and solving problems with the data.
Go to the Teams worksheet. Takara asks you to correct the errors in the worksheet. Correct the first error as follows:

a. Use the Trace Precedents arrows to find the source of the #VALUE! error in cell C8.

b. Use the Trace Dependents arrows to determine whether the formula in cell C8 causes other errors in the worksheet.

c. Correct the formula in cell C8, which should add the baseball registration fee per person (cell C4) and the equipment fee (cell C7), and then multiply the result by the minimum number of campers (cell C6).

d. Remove the trace arrows.

2. Correct the Name error in cell C22 as follows:

a. Use any error-checking method to determine the source of the error in cell C22, which should calculate the average revenue per week.

b. Correct the error by editing the formula in cell C22.

3. Correct the divide by zero errors as follows:

a. Evaluate the formula in cell C18 to determine which cell is causing the divide by zero error.

b. Correct the formula in cell C18, which should divide the revenue per session (cell C16) by the minimum number of campers (cell C6).

c. Fill the range D18:G18 with the formula in cell C18. 

4. Takara suspects that the remaining divide by zero errors and the two negative values in the range E16:E18 are related to the zero value in cell E6. She wants to make sure that anyone entering the minimum number of campers enters a number greater than zero.
Add data validation to the range C6:G6 as follows:

a. Set a data validation rule for the range C6:G6 that allows only whole number values greater than 0.

b. Add an Input Message using Number of Campers as the Input Message Title and the following text as the Input message:
Enter the minimum number of campers for this session. 

c. Add an Error Alert using the Stop style, Campers Error as the Error Alert Title, and the following text as the Error message:
The minimum number of campers must be greater than 0. 

5. Identify the invalid data in the worksheet and correct the entry as follows:

a. Circle the invalid data in the worksheet.

b. Type 10 as the minimum number of campers for the lacrosse sessions (cell E6).

c. Verify that this change corrected the remaining divide by zero errors and resulted in positive values in the range E16:E18.

6. Go to the Private Lessons worksheet. This worksheet analyzes financial data for private and semi-private lessons, which the camp runs throughout the day. Takara has already created a scenario named Current Campers that calculates profit based on the current number of campers enrolled for each session. She also wants to calculate profit based on the maximum number of campers.
Add a new scenario to compare the profit with maximum enrollments as follows:

a. Use Max Campers as the scenario name.

b. Use the enrolled campers per day data (range C9:G9) as the changing cells.

c. Enter cell values for the Max Campers scenario as shown in bold in Table 1, which are the same values as in the range C8:G8.

* Table 1: Cell Values for the Max Campers Scenario

7. Takara also wants to calculate profit based on the minimum number of campers.
Add another new scenario to compare the profit with low session enrollment as follows: 

a. Add a scenario to the worksheet using Min Campers as the scenario name.

b. Use the enrolled campers per day data (range C9:G9) as the changing cells.

c. Enter cell values for the Min Campers scenario as shown in bold in Table 2.

* Table 2: Cell Values for the Min Campers Scenario

8. Show the Min Campers scenario values in the Private Lessons worksheet.

9. Go to the Revised Fees worksheet. Takara is considering whether to change the coaching fees for the private lessons. She has created three scenarios on the Revised Fees worksheet showing the profit with a $5 or $10 increase or a $5 decrease to the coaching fees.
Compare the average profit per session based on the scenarios as follows:

a. Create a Scenario Summary report using the average profit per session (range C11:G11) as the result cells to show how the average profit changes depending on the coaching fee changes. 

b. Use Revised Fees Scenario Report as the name of the worksheet containing the report.

10. Takara also wants to focus on one or two types of private lessons at a time when comparing the average profit per session. Return to the Revised Fees worksheet and create another type of report as follows:

a. Create a Scenario PivotTable report using the average profit per session (range C11:G11) as the result cells to compare the average profit depending on the fee changes in a PivotTable.

b. Use Revised Fees PivotTable as the name of the worksheet containing the PivotTable.

c. Format cells B4:F6 in the Revised Fees PivotTable worksheet using the Accounting number format with 0 decimal places and $ as the symbol.

11. Go to the Games worksheet. Takara wants to determine the number of games the camp can hold on Fridays and Saturdays to make the highest weekly profit without interfering with practices, which are also scheduled for Fridays and Saturdays and use the same resources.
Use Solver to find this information as follows:

a. Use the total weekly profit (cell H17, named Total_Weekly_Profit) as the objective cell in the Solver model, with the goal of determining the maximum value for that cell.

b. Use the number of Friday and Saturday games for the five sports (range C5:G6) as the changing variable cells.

c. Determine and enter the constraints based on the information provided in Table 3.

d. Use Simplex LP as the solving method to find a global optimal solution.

e. Save the Solver model in cell B27.

f. Solve the model, keeping the Solver solution.

12. Takara wants to document the answer Solver found, including the constraints and a list of the values Solver changed to solve the problem. Produce an Answer report for the Solver model as follows:

a. Solve the model again, this time choosing to produce an Answer report.

b. Use Games Answer Report as the name of the worksheet containing the Answer report.
