Parameter: If a method needs to receive arguments, then the method call should pass some parameters. The parameter variable is assigned with the value of an argument when the method is called. Reference parameter: Reference parameter is one of the special parameter variable types that are used for two-way communication purposes. If an argument is passed to a reference parameter, it will not get the copy of the argument value. Instead, it acts as a reference for the argument passed to it. If any change or modifications is done to the reference parameter, then that change will be reflected to the argument it references. When an argument is passed to “ref” parameter, then the value of the argument must be set.

Question

Chapter 6.4, Problem 6.12CP

Program Plan Intro

Parameter:

If a method needs to receive arguments, then the method call should pass some parameters.

The parameter variable is assigned with the value of an argument when the method is called.

Reference parameter:

Reference parameter is one of the special parameter variable types that are used for two-way communication purposes.

If an argument is passed to a reference parameter, it will not get the copy of the argument value. Instead, it acts as a reference for the argument passed to it.

If any change or modifications is done to the reference parameter, then that change will be reflected to the argument it references.

When an argument is passed to “ref” parameter, then the value of the argument must be set.

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…
