I Need Help With Making This Program Work

Question

The directions for this program:
Enhance the Student class to contain an Advisor. The advisor has a name (type Name), phone number (type String). Place edits in the Name class to validate that the length of the first name is between 1 and 15, middle inital <= 1, and lastName is between 1 and 15. Throw an IllegalArgumentException if the edits are not met. The advisor attribute in the Student class should replace the advisorName. Document the Name, Advisor, and Student classes including the preconditions and postconditions where necessary. Create a test class that will instantiate a Student, fully populate all of its fields and print it out. Do not document the test class. Submit for grade Student.java, Advisor.java, and Name.java.
public class Student
     private Advisor advisorName;
     private Advisor phoneNumber;
     public void setAdvisorName(Advisor anAdvisorName)
         advisorName = anAdvisorName;
     public Advisor getAdvisorName()

     public void setPhoneNumber(Advisor aPhoneNumber)
         phoneNumber = aPhoneNumber;
     public Advisor getPhoneNumber()

        Calculates length of the first name.
        (Postcondition: getFirstName() >= 0)
        @param s the length of the first name to calculate

           midInit = aMidInit;
        Calculates length of the last name.
        (Postcondition: getLastName() >= 0)
        @param s the length of the last name to calculate
        (Precondition: length of aLastName > 0 and <= 15)
     public void setLastName(String aLastName)

           throw new IllegalArgumentException();

}I can't get the test class to compile and i'm not sure if this is what i'm suppose to do

Answer 1

public class Test
public static void main(String[] args)
Student st = new Student();
Advisor advisor = new Advisor();
st.setAdvisor(advisor);
Name name1 = new Name();
name1.setFirstName("Jake");
name1.setLastName("Schmidt");
name1.setMidInit("K.");You have the general idea, I think. You are just doing it backwards.
You create and advisor and assign it to a student. But you don't give
the advisor a name until after you assign it to the student.
You should create an advisor, give the advisor a name and then add it to the student.
//create the name
Name name1 = new Name();
name1.setFirstName("John");
name1.setLastName("Smith");
name1.setMidInit("K.");
//create the advisor
Advisor advisor = new Advisor();
advisor.setAdvisorName(name1);
//create the student
Student student = new Student();
//assign the advisor to the student
student.setAdvisor(advisor);
//now the student has an advisor named John K. Smith
//What is the name of the advisor?
String name = st.advisor.getAdvisorName().getFullName();
//I know that line looks complicated...but that's how you have created your class structure.
Instead you could have done:
Class Student{
private Advisor advisor;
public String getAdvisorName(){
return advisor.getFullName();
class Advisor{
private Name advisorName;
public getFullName(){
return advisorName.getFullName();
This way, if you wanted to know the advisor's name you would go:
String name = st.getAdvisorName();
which is much easier.
I think it would be much easier to help you if we were both in the same room, on the same computer :)
