COSC 1437 – PROJECT
TITLE
File access – Array Access – User-defined function – Student Grading
HOW TO DO PROJECT
*From now and on yourLastName will be changed to your last name.
*Your program should change White to your last name.
*Your program should change JAMES SMITH to your name.
*Change Mary Lane to the name of user who is using the Investment Application entered from the keyboard.
*Write the file name as the first comment line at the top of the program.
*After running your program, get the picture of the output window from your program with your name on to paste at the bottom of the pseudo-code to turn in.
*Step1: Read the requirement of each part; create the UML of data type class, write the pseudo-code of driver class in a word document by listing the step by step what you suppose to do in main() and then save it with the name as Project_pseudoCode_yourLastName.
*Step2:
-start editor (for example eclipser) create the project with the following project name:
FA2021_PROJECT_yourLastName
-add data type class:
FA2021_Student_yourLastName
-add a driver class (that contain main()
FA2021_CSGradingStudentsApplication_yourLastName
*Step3: follow step by step in the pseudo-code (or the flowchart) to write the java code in main() or driver class.
*Step:4 compile and run the program. Computer Science homework help.
*Step5: debug if there are any errors to complete the program.
PROJECT requirement
Use Java to provide the application that helps to calculate the numeric grade and determine the letter grade of students based on the scores of 8 assignment types: policy quiz, quizzes, homework, labs, project, discussion topic, teamwork, and tests where policy quiz is an extra credit.
The course name, student id, last name, first name and all the scores of 8 assignment types of one student are provided from the keyboard.
The application provides 3 tasks
FA2021_CSGradingStudentsApplication_Smith.java

TO DO THIS LAB, WE NEED TWO CLASSES:
-DATA TYPE CLASS: FA2021_Student_yourLastName
-DRIVER CLASS: FA2021_CSGradingStudentsApplication_yourLastName
DATA TYPE CLASS
Class FA2021_Student_yourLastname
-The class should hold the information relating to this project: course name, student id, last name, first name,
And 3 arrays of size 8:
- Float Array to hold the max score of each assignment type
- Float Array to hold the total of scores of each assignment type
- String Array to hold the 8 strings of 8 lists of assignment scores
All 3 these arrays have size 8.
Index 0: store information of policy quiz
Index 1: store information of quizzes
Index 2: store information of homework
Index 3: store information of labs
Index 4: store information of project
Index 5: store information of teamwork
Index 6: store information of topics
Index 7: store information of tests

total max score = sum of all values in 8 elements in 8 elements of the max score array
total student scores = sum of all values in 8 elements of the student scores array
calculate numeric grade = 100* total student scores/total max score
method to determine letter grade,
| Letter Grade | Numeric grade |
| A | 90 – 100 |
| B | 80-89 |
| C | 70-79 |
| D | 60-69 |
| F | 0-59 |

-First create the following arrays size 8:
*Constant string aarray:
ASSIGNMENT_NAMES to store name of 8 assignment types
{ “POLICY QUIZ”, “QUIZZES”, “HOMEWORK”, “LABS”, “PROJECT”, “TEAMWORK”, “DISCUSSION TOPIC”, “TESTS” };
*int array assignmentSize size 8; // to store the number of assignments each type, for example assignmentSize[7]=3 if there are 3 tests, assignmentSize[1] = 10 if there are 10 homework
*float maxScore; size 8 to store the max scores of assignments, for example, maxScore[0] = 5 because only 1 policy quiz and max score is 5, maxScore[7] = 300 because max score of a test is 100 * there are 3 tests. Computer Science homework help
*float studentScores size 8 to store the scores of students, for example studentScores[7] stores total scores of 3 student tests. studentScores[3] stores total scores of student labs
*String arrary stringScores size 8 that keep student scores in string format
stringScores [0] =”5”
stringScores[7] = “75.00 82.50 78.25”
Read general information of assignments:
The course name
How many assignments of each type> to fill up the array assignmentSize
What is max score of each assignment to fill out the array maxScore by the formula:
Max score = max score of each unit * number assignment
Display the menu of Tasks to all users to select the task
TASK1:
-Read information about the student id, last name, first name and the scores of each assignment type
Create the object of data type class FA2021_Student_yourLast name to pass all the information to the object
Use the object to access the methods of class FA2021_Student_yourLastname to display the output of task1
-store the grade information to the output file studentGrades.txt in the requested format:
TASK2
Ask for the id of student who you want to check the grade record
Open file studentGrade.txt to read
For each line, split information to get the student id
Compare student id with id; if they are the same then split all information of the line
Create the student object of data type class
Using the object to access the method of data type class to print out the requested output of the grade of one student
TASK3
-open file studentGrades.txt to read
-read file, for each line, split information and assign to variables to create the object of class FA2021_Adult_yourLastName
Then use the object to access the method in data type class to print output grade of student
-read and print the grade of all students in file
