Question
Create a class named CollegeCourse that includes data fields that hold the department (for example, ENG), the course number (for example, 101), the credits (for example, 3), and the fee for the course (for example, $360). All of the fields are required as arguments to the constructor, except for the fee, which is calculated at $120 per credit hour. Include a display() method that displays the course data. Also create a program that displays the course data. Use Constructors. Save the files as CollegeCourse.java
Explanation / Answer
PROGRAM:
import java.io.*;
import java.util.Scanner;
public class CollegeCourse {
String department;
int courseNumber;
int credits;
double fee;
CollegeCourse(String department,
int courseNumber,
int credits)
{
this.department=department;
this.courseNumber=courseNumber;
this.credits=credits;
}
double getFee()
{
fee=120*this.credits;
return fee;
}
void display()
{
System.out.println(department+" "+courseNumber+" "+credits+" "+getFee());
}
public static void main(String []args)throws IOException
{
System.out.println("Enter how many courses you to enter:");
Scanner scan=new Scanner(System.in);
int size=scan.nextInt();
CollegeCourse []c=new CollegeCourse[size];
for(int i=0;i<size;i++)
{
System.out.println("Enter Course:");
String course=scan.next();
System.out.println("Enter CourseNumber:");
int courseNO=scan.nextInt();
System.out.println("Enter Credits:");
int credits=scan.nextInt();
c[i]=new CollegeCourse(course,courseNO,credits);
}
for(int i=0;i<size;i++)
{
c[i].display();
}
}
}
}
OUTPUT:
