I have been working on writing a java program (that goes with another I just got finished- see below CollegeCourse & Student) that prompts user to put in letter grades (A-F) for 5 different courses for a total of 10 different students. So I need to prompt user to input a student ID, then the 1st course ID, then the grade, then the 2nd course ID- then grade, the the 3rd course ID then grade, then the 4th course ID then grade, then finally the 5th course ID then grade. Then it needs to go through the same thing 10 times (for a total of 10 students). It also says the user is asked to "Enter ID for student #s" where s is an integer from 1 through 10, indicating the student (and I don't really know how to do that but I tried as I googled java); AND "Enter course ID #n, where n is an integer from 1 through 5, indicating the course number. And last it needs to verify for grade entry that only the A, B, C, D, or F are entered. I started writing notes to try to keep track of where thing are but I'm getting really confused. When I tried to compile it of course it has errors... So I really need some guidence/ help you can provide. Here's my code: import java.util.*; import stud.*; class InputGrades extends CollegeCourse { public static void main(String[] args) //main method { student[] students = new Student[10]; //declare array for 10 students info entered for int t,r,d; //declare variables for stu id, course numb, gradesand initialize String courseIDEntry, entry = " "; int sIDEntry, CreditHoursEntry; char letterGradeEntry= ' '; boolean isLetterGradeGood = false; //to verify letter A=F is put in final int NUM_COURSEID=5; //variable cannot be changed to have more than 5 courses per student char[]lettergrade= ['A', 'B', 'C', 'D', 'F']; //declare array of 5 grades for(t=0;t< students.length; ++t) //for loop that runs to let only 10 students ID's to be entered { Student stu = newStudentDetails(); //create student Scanner input = new Scanner(System.in); //prompt user to put in student ID do System.out.print("Enter student #" + (t+1) + ", enter the student ID number"); for(t=0;t
