Java codding Please
Problem: Winston-Salem State University’s Office of Budget Management needs a java program to assist in determining how much money can be saved by cancelling classes in the English, Social Science, and Mathematics Departments next semester. It costs the University $3000 to implement each class. The criteria used for cancelling classes are as follows:
. Classes with less than 10 students
. Classes that meet after 6 pm (1800) and taught by Part-time instructors
They have contracted you to prepare a report based on the information in the database(textfile). The database (budget.txt) contains the following information:
- Course ID (i.e. ENG2301-01)
- Course Title
- Time Course Start (in military time)
- Enrollment
- Type Instructor (F- Fulltime, P-Part-time)
Sample Data:
Eng2310-01/ Intro to Speech/1700/28/F
Secondly, they need you to prepare a report containing the following information:
1- Read and display the contents of the file.
2- Display the course information for all cancelled classes.
3- Display the reason(s) why the course was cancelled.
4- Display a list of savings by department.
5- Display the total amount that the university will save by cancelling the classes.
6- Determine and display the department that will save the most from cancelling classes
Your program should produce output similar to the following:
