Exact Photo Service purchased a new color printer at the beginning of Year 1 for $39,700. The printer is expected to have a four-year useful life and a $3,700 salvage value. The expected print production is estimated at $1,770,500 pages. Actual print production for the four years was as follows:

The printer was sold at the end of Year 4 for $4,100.

This project will be an exercise in using all that we have covered in these past two weeks: Arrays (one and multidimensional arrays), branching, and input and output files.

Components:

A class called YourLastNameGradebook (Yes, YourLastName IS  your last name!!!)

And an external class called SomeNeatExternalSoundingName. This external class will have at least 2 methods: readData and writeData

This project will include

The class with the main method and the other useful methods that will 1) display the arrays, 2) find the averages and store them, 3) find the grades and store them, 4) and display a chart of the final array results to the terminal window.

The external class will 1) read from the input file and 2) write to an output file.

YourLastNameGradebook class's main method will be made up of declarations and method calls. There should be no other code in the main method. (Except for one single print statement stating that the program is finished!)

Declarations:

• Declare a one-dimensional array that contains the names of 5 students (the names will be read in as first and last and be concatenated into a one-dimensional names array in the order of last, first with a comma between the names)
• Create a multidimensional array that contains 3 test scores PLUS one more element (this extra element will be used later to store the computed average of these 3 test scores) for each of the 5 students.
• Declare a one-dimensional array that will contain the letter grades for each of the 5 students.

Actions needed: Note - Do use the size of the array for your for loops, notthe value 5.

1) Read in (Invoke the readData method in the external class ):

The input file looks like this:   project2IN.txt

Leia Organa 98.0 95.5 100.0
Fred Flintstone 65.0 74.5 76.25
Sheldon Cooper 100.0 100.0 99.0
Stan Marsh 89.0 84.0 80.5
Lisa Simpson 93.0 94.5 92.0

When you open the input file, echo this to the terminal window.

The array of names will be read in from the input file. (The names will be read in as first last but need to be rearranged to last, first when being read in)
This array of scores will be read in from the input file.

The last element in the scores array will have a zero in it. This will be reserved for the averages (later).

When you close the input file, echo this to the terminal window.

After reading in the data: Row zero from the names array corresponds to row zero from the scores array:

names array contains 5 names:

element: Contents:

Scores array contains 5 rows of 4 elements each

2) In YourLastNameGradebook class, invoke the method to display the data using a displayData method:

Display the data (using a displayData method) in the terminal window as it is stored in both of the arrays.

Data read in:

last, first: score1, score2, score3

last, first: score1, score2, score3

last, first: score1, score2, score3

last, first: score1, score2, score3

last, first: score1, score2, score3

(Formatting at this point is not important. Include at least one space! This is just echoing what was entered!)

3) Invoke a method that will compute the average in the scores array

• Store the computed averages into the last column element of each row of the scores array.

4) Invoke a method that will compute the grade for each student

For each student, determine the average score from the three grades and the grade of A, B, C, D, or F   

• Store the letter grade into a one-dimensional array called letterGrade that corresponds to that student. (I used: to get an A, they need 89.5 and so on – use the full letter grade percentages from the class syllabus)

5) Invoke another displayData method that will print out the names, scores, and grades for each student in the terminal window.

6) Invoke the method in the External class that will write the clean chart to the output file project2OUT.txt

• When you open the output file, echo this to the terminal window.
• Write a neat chart of the names, the scores, and the grades received.
• When you close the output file, echo this to the terminal window.

7) When done, the last statement of the main is to be an output statement telling the user that the program is finished.

Output is to be neat and clean. Use blank spaces for readability in both the output file and in the terminal window.

Upload (to one of your pairs’ Canvas account) ALL the files that are needed for grading including BOTH .java files and both .txt files:

• include the input file: project2IN.txt
• and the output file: project2OUT.txt
• also the .java file that contains your main method as well as the .java file that contains the external method.

Extra Credit:
1) Use printf to create a neat chart with a chart title (centered above the output) and headers for the data similar to the following.  (2 points)

==========================================================================
                        Student Grades

Name                        Score1     Score2       Score3       Average    Grade
==========================================================================
Organa, Leia             98.00         95.50 100.00     .00              x
Flintstone, Fred        65.00         74.50   76.25     .00               x

and so on...

2) Insert a first new line into your input file. Alter this first line to include an integer value to represent the number of rows to be read in as a reference that will declare the sizes of the arrays to be of that size.

(2 points)

Be SURE that both names appear in the beginning comments!  Otherwise only one of you will get credit.
This is what will be displayed to the terminal window:  This could be cleaned up to be more readable.

It is now January 1, 2019, and you are considering the purchase of an outstanding bond that was issued on January 1, 2017. It has an 8.5% annual coupon and had a 15-year original maturity. (It matures on December 31, 2031.) There is 5 years of call protection (until December 31, 2021), after which time it can be called at 108—that is, at 108% of par, or $1,080. Interest rates have declined since it was issued, and it is now selling at 111.55% of par, or $1,115.50.

a. What is the yield to maturity? Do not round intermediate calculations. Round your answer to two decimal places.

What is the yield to call? Do not round intermediate calculations. Round your answer to two decimal places.

b. If you bought this bond, which return would you actually earn?

I. Investors would not expect the bonds to be called and to earn the YTM because the YTM is less than the YTC.

II.Investors would expect the bonds to be called and to earn the YTC because the YTC is less than the YTM.

III. Investors would expect the bonds to be called and to earn the YTC because the YTC is greater than the YTM.

IV. Investors would not expect the bonds to be called and to earn the YTM because the YTM is greater than the YTC.

c. Suppose the bond had been selling at a discount rather than a premium. Would the yield to maturity have been the most likely return, or would the yield to call have been most likely?

I. Investors would expect the bonds to be called and to earn the YTC because the YTC is greater than the YTM.

II. Investors would expect the bonds to be called and to earn the YTC because the YTC is less than the YTM.

III. Investors would not expect the bonds to be called and to earn the YTM because the YTM is greater than the YTC.

IV. Investors would not expect the bonds to be called and to earn the YTM because the YTM is less than the YTC.
