Question

Create student object class (Student.java)

Student objects should have the following attributes:

student name
major
class name
course id
grade
credits

Create Course object class (Course.java)

Course object should be the following attributes:

course id
instructor id
room id

Create testStudent class

Output

Create a report that has appropriate headings and 1 line of detail for each student record read in. Detail lines should include the following information:

student name,
class id,
Instructor id,
room id,
grade,
credits,
comment

Read student information, process the information and print an output line for each student record in the ClassesData.dat file. You will also need the CoursesData.dat file for courses information.
- A second version of the data is available. You can use either version of these files. Just be sure to zip the data files your program solution uses, with your submission: NewCoursesData.txt , NewClassesData.txt

The comments section of the detail line should display the String "Great Job!" if the student gets an 'A' grade.

Zip these five files into 1 zipped file named <yourlastname>Final(example watneFinal):

Student.java
Course.java
testStudent.java
ClassesData.dat
CoursesData.dat.

Submit the zipped file as an attachment.

I have two pictures. The first picture, that error appears when I try to run the Java application for the Student.java and Course.java.

The second picture, errors I receive when trying to compile the testStudent.java. I presume I'll probably get the same error as the Student and Course so I would like that fixed as well.
