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() }

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
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
