Answer to Question #281523 in Java | JSP | JSF for jhadz

Question

·        Ask the first name, middle initial and last name of the student.

·        Prompt the user to select between old student and new student by pressing either O (old student) or N (new student).

·        If O is pressed, ask the student to enter the following grades per term:

o  Prelim

o  Midterm

o  Prefinals

o  Finals

·        Compute the final grade of the student by using given formula: FG = ((Prelim * 20%) + (Midterm * 20%) + (Prefinals * 20*) + (Finals * 40%)). Display the full name of the student with his/her accumulated grade using the format given.

·        If N is pressed, ask the student to enter his/her average grade then display the full name grade.

·        Grade Format:

o  1.00 = 99 – 100

o  1.25 = 96 – 98

o  1.50 = 93 – 95

o  1.75 = 90 – 92

o  2.00 = 87 – 89

o  2.25 = 84 – 86

o  2.50 = 81 – 83

o  2.75 = 76 – 80

o  3.00 = 75

o  5.00 = Below 75

·        If an invalid letter is pressed, display an error message.
