Question

//Create a CollegeStudent class. This class will contain data fields that hold a student's first name, last name, enrollment date, and projected graduation date, using the GregorianCalendar class for each date.
//Provide get() and set() methods for each field.
// Also provide a constructor that requires first and last names and enrollment date, and sets the project graduation date to exactly four years after enrolment. Save the class as CollegeStudent.java.
import java.util.*;
import javax.swing.*;
class CollegeStudent {
private String firstName;
private String lastName;
private GregorianCalendar enrollment;
private GregorianCalendar graduation;
public static void main (String[] args){

}

public String getFirstName(String firstName) {
return firstName;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public String getLastName(String lastName) {
return this.lastName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}

public GregorianCalendar getEnrollmentDate() {
return this.enrollment;
}

public void setEnrollmentDate(GregorianCalendar enrollment) {
this.enrollment = enrollment;
}

public GregorianCalendar getGraduationDate() {
return this.graduation;
}

public void setGraduationDate(GregorianCalendar graduation, int year) {
year += 4;
this.graduation = graduation;

}


public void display() {
JOptionPane.showMessageDialog(null, "First Name: " + firstName + " Last Name: " + lastName + " Enrollment Date: " + enrollment + " Graduation Date: " + graduation);
}
}
