Question

Exercise 13: Course Class Project Name: A1 E13 YourLastName YourFirstName Write the implementation of the class Course according to the requirements listed below. Data fields o A String courseDept that stores the course department ("CS", "Math etc.. o An int courseNo that stores the course number (170, 150, etc.). o An int courseUnits that stores the number of units for the course. o Remember that data fields are always private. Default constructor o Initializes all data fields to default values. overloaded constructor o Parameters a string storing the course department, an int storing the course number, and an int storing the number of units. o Initializes all data fields to the given values. Method getCourseDept o Returns the course department. Method getCourseNumber o Returns the course number. Method get CourseUnits o Returns the number of units for the course. Method setCourseDept o Parameter: a String storing a course department. o Re-sets the course department of the calling object with the value passed by the parameter. Method set Course Number o Parameter: an int storing a course number. o Re-sets the course number of the calling object with the value passed by the parameter. Method setCourseUnits o Parameter an int storing the units for the course o Re-sets the course units of the calling object with the value passed by the parameter. Method compareUnits o Parameter: an object of the Course class. o A Boolean method that returns true if the calling object has the same number of units of the parameter object, and false otherwise. Method printcourselnfo o Prints the course information in the following format: CS 170 (4 units)

Explanation / Answer

Course.java

public class Course {
   //Declaring instance variables
   private String courseDept;
   private int courseNo;
private int courseUnits;
  
//Zero arguments constructor
public Course() {
       super();
       this.courseDept = "N/A";
       this.courseNo = 0;
       this.courseUnits = 0;
   }
  
   //Parameterized constructor
   public Course(String courseDept, int courseNo, int courseUnits) {
       super();
       this.courseDept = courseDept;
       this.courseNo = courseNo;
       this.courseUnits = courseUnits;
   }

   //getters and setters
   public String getCourseDept() {
       return courseDept;
   }

   public void setCourseDept(String courseDept) {
       this.courseDept = courseDept;
   }

   public int getCourseNo() {
       return courseNo;
   }

   public void setCourseNo(int courseNo) {
       this.courseNo = courseNo;
   }

   public int getCourseUnits() {
       return courseUnits;
   }

   public void setCourseUnits(int courseUnits) {
       this.courseUnits = courseUnits;
   }
  
   //This method comparing two courses
boolean compareUnits(Course cs)
{
   if(this.courseUnits==cs.getCourseUnits())
       return true;
   else
       return false;
}

//this method will print the course class object info
public void printCourseInfo()
{
   System.out.println("The "+courseNo+" course, "+courseDept+" department, has "+courseUnits+" units.");
}

}

____________________

CourseTester.java

public class CourseTester {

   public static void main(String[] args) {
      
       //Creating the Course class objects by passing values as arguments
       Course course1=new Course("CS",170,4);
       Course course2=new Course("CS",150,3);
       Course course3=new Course();
      
       //Displaying the Course class info
       course1.printCourseInfo();
       course2.printCourseInfo();
       course3.printCourseInfo();
      
       //Creating the Course class objects by passing values as arguments
       Course course4=new Course("Math",200,5);
      
       //Comparing the two Course class units
       boolean bool=course1.compareUnits(course2);
       if(bool)
           System.out.println("The Two "+course1.getCourseDept()+" have the same units");
       else
           System.out.println("The Two "+course1.getCourseDept()+" do not have the same units");

   }

}

_____________________

Output:

The 170 course, CS department, has 4 units.
The 150 course, CS department, has 3 units.
The 0 course, N/A department, has 0 units.
The Two CS do not have the same units
