For example: The information and scores of student James Smith will be combined in one string as below: 1234567,Smith,James,4691234567-2.50,3.50,4.00,5.00,3.25,4.50,3.50,5.00,5.00,4.25,2.50,2.50,5.00,5.00- 8.50,9.00,10.00,8.50,9.25,7.50,6.75,8.00,9.00,10.00-30.00,38.50,29.25,23.50,25.00,22.50,28.00-88.50,75.50,78.50-75.50-10.00-20.00-5.00-0.00- 0.00-X -Write this string to the output file tempFile.txt ? read next line from input file then do the same until the end of the input file ? at the end of this task2 do the following lines of code: + close input file + close output file (file tempFile.txt) + delete input file + rename file tempFile.txt to the same name with input file ifile.close(); ofile.close(); file.delete();// input file delete temp.renameTo(file); //rename tempFile to input file name TASK3: GRADING -open the above file to read (input file) -open a file tempFile.txt to write (output file) -read file: ? read one line from the input file that should be in the following format: 1234567,Smith,James,4691234567-2.50,3.50,4.00,5.00,3.25,4.50,3.50,5.00,5.00,4.25,2.50,2.50,5.00,5.00- 8.50,9.00,10.00,8.50,9.25,7.50,6.75,8.00,9.00,10.00-30.00,38.50,29.25,23.50,25.00,22.50,28.00-88.50,75.50,78.50-75.50-10.00-20.00- 5.00-0.00-0.00-X -split information from the line by using delimeter comma (,) or dash (-); then assign each piece of information to the following For example the line is read from file: 1234567,Smith,James,4691234567-2.50,3.50,4.00,5.00,3.25,4.50,3.50,5.00,5.00,4.25,2.50,2.50,5.00,5.00- 8.50,9.00,10.00,8.50,9.25,7.50,6.75,8.00,9.00,10.00-30.00,38.50,29.25,23.50,25.00,22.50,28.00-88.50,75.50,78.50-75.50-10.00-20.00- 5.00-0.00-0.00-X Will be splitted into: Id = 1234567 Last name = Smith First name = James Phone = 4691234567 Quizzes = 2.50,3.50,4.00,5.00,3.25,4.50,3.50,5.00,5.00,4.25,2.50,2.50,5.00,5.00 Homeworks = 8.50,9.00,10.00,8.50,9.25,7.50,6.75,8.00,9.00,10.00 Labs = 30.00,38.50,29.25,23.50,25.00,22.50,28.00 Tests = 88.50,75.50,78.50 Project = 75.50 Discussion = 10.00 Team work = 20.00 Extra credit = 5.00 Sum of score = 0.00 Percentage = 0.00 Letter grade = X //these scores are stored in array //these scores are stored in array //these scores are stored in array //these scores are stored in array -After calculate the percentage and determine the letter grade, you combine all the information and scores and result to one string as you did in Task2 -Write the string to the output file tempFile.txt -Read another line the do the same until the end of input file ? After finishing all students do the same thing as task2 to rename the tempFile.txt back to orignial input file ? Also, display the result of class on the screen in the following format; GRADING CLASS Total students: Grade A: Grade B: Grade C: Grade D: Grade F: 20 5 25% 10 50% 4 20% 0 0% 1 5%
