Explanation of Solution

Program:

File name: “RetirementGoal.java”

//Import necessary header files

import java.util.Scanner;

//Define a class named RetirementGoal

public class RetirementGoal

{

    //Define main method

    public static void main (String[] args)

    {

Please answer JAVA OOP problem below: You are working at a university that tracks students. Each student is identified by their name and faculty advisor. Each faculty advisor is identified by their name, department, and maximum number of students they can advise. Using solid OO design principles, create a modular program that implements all the classes for the problem and also creates an implementation class that gathers user input for one student and then prints out the information gathered by creating the appropriate data definition and implementation classes. All data must be validated. I have given the code so far: Implementation: import javax.swing.JOptionPane; public class Implementation { public static void main(String[] args) { FacultyAdvisor facultyAdvisor = new FacultyAdvisor("Sharmin Sultana", "IT", 30); Student student = new Student("John", facultyAdvisor); JOptionPane.showMessageDialog(null, student.toString()); } } Student: public…
