Homework SourseDesign a class named Course The class contains Private data
Design a class named Course. The class contains:
Private data fields, including courseNumber, courseTitle, and creditHours
Getter and setter methods for all data fields
A default constructor (assign initial values of your choice)
A constructor that creates a Course object with courseNumber courseTitle, and creditHours.
Design a class named Student. The class contains:
Private data fields, including student name, and a course array that contains all courses the student is currently taking.
Getter and setter methods for all data fields
A default constructor (assign initial values of your choice)
A constructor that creates a student with name. Initialize the course list with the size of 4 course array-assuming each student is taking 4 courses. (hint: this constructor takes a name as parameter, it signature looks like: Student(String aName))
A method named getTotalCreditHours that calculates and returns the total credit hours of a student.
A method named print that print student information in the following format:
