Question

need help understanding in java. 

Given main(), define a Course base class with methods to set and get private fields of the following types:

  • String to store the course number
  • String to store the course title

Define Course's PrintInfo() method that outputs the course number and title.

Then, define a derived class OfferedCourse with methods to set and get private fields of the following types:

  • String to store the instructor's name
  • String to store the location
  • String to store the class time

Ex. If the input is:

ECE287 Digital Systems Design ECE387 Embedded Systems Design Mark Patterson Wilson Hall 231 WF: 2-3:30 pm

the output is:

Course Information: Course Number: ECE287 Course Title: Digital Systems Design Course Information: Course Number: ECE387 Course Title: Embedded Systems Design Instructor Name: Mark Patterson Location: Wilson Hall 231 Class Time: WF: 2-3:30 pm

CODE PROVIDED:

CourseInformation.java (READ ONLY)

import java.util.Scanner;

public class CourseInformation {
   public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);

      Course myCourse = new Course();
      OfferedCourse myOfferedCourse = new OfferedCourse();

      String courseNumber, courseTitle;
      String oCourseNumber, oCourseTitle, instructorName, location, classTime;

      courseNumber = scnr.nextLine();
      courseTitle = scnr.nextLine();

      oCourseNumber =  scnr.nextLine();
      oCourseTitle =  scnr.nextLine();
      instructorName = scnr.nextLine();
      location = scnr.nextLine();
      classTime = scnr.nextLine();

      myCourse.setCourseNumber(courseNumber);
      myCourse.setCourseTitle(courseTitle);
      myCourse.printInfo();

      myOfferedCourse.setCourseNumber(oCourseNumber);
      myOfferedCourse.setCourseTitle(oCourseTitle);
      myOfferedCourse.setInstructorName(instructorName);
      myOfferedCourse.setLocation(location);
      myOfferedCourse.setClassTime(classTime);
      myOfferedCourse.printInfo();

      System.out.println("   Instructor Name: " + myOfferedCourse.getInstructorName());
      System.out.println("   Location: " + myOfferedCourse.getLocation());
      System.out.println("   Class Time: " + myOfferedCourse.getClassTime());
   }
}

Course.java 

public class Course{
   // TODO: Declare private fields

   // TODO: Define mutator methods - 
   //       setCourseNumber(), setCourseTitle()


   // TODO: Define accessor methods - 
   //       getCourseNumber(), getCourseTitle()

   // TODO: Define printInfo()
 
}

OfferedCourse.java

public class OfferedCourse extends Course {
   // TODO: Declare private fields

   // TODO: Define mutator methods -
   //      setInstructorName(), setLocation(), setClassTime()


   // TODO: Define accessor methods -
   //      getInstructorName(), getLocation(), getClassTime()

}
