[Solved] Lab Use List Simulate Manage Program Study Program Study Refer List Courses Student Takes Q37275302

In this lab, you use a list to simulate and manage a program ofstudy. By program of study, we refer to list of courses that astudent takes to fulfill degree requirements.

The program consists of three classes: a Course class thatrepresents a course that might be taken by a student, aProgramOfStudy class that represents a list of courses taken andplanned for an individual student and POSTester class that acts asa driver class.

Course Class

 Define a Course a class that has four instance variables:Prefix (a String), number (an integer), title (a String) and grade(a String). For instance for the following course:

CS 101: Introduction to Programming

“CS” is the prefix, 101 is the course number, “Introduction toProgramming” is the tile and grade might be empty or any of lettersthat represent a grade.

 Define 2 constructors for the course class: one thatconstructors the course the specified information and has thefollowing signature:

public Course(String prefix, int number, String title, Stringgrade)

The second constructor constructs the course without the gradeand has the following signature:

public Course(String prefix, int number, String title)

 Define getter methods for all of variables and setter methodonly for grade that might be set later.

 Define method boolean taken() that returns true if a coursehas a grade associated with it.

 Define method boolean equals(Object other)that Determines ifthis course is equal to the one specified, based on the coursesprefix and number.

 Define toString() method that Creates and returns a stringrepresentation of this course similar as follows:

CS 101: Introduction to Programming [A-]

 Modify course class to implement serializable interface.Implementing serializable interface allows you to save objects of aclass and load them for the future runs of the program.

ProgramOfStudy Class

 Define ProgramOfStudy a class that has one instance variables:the instance variable called list is declared to be of type List,which refers to the list interface.

 Define a constructor public ProgramOfStudy(). In theconstructor, a new LinkedList object is instantiated.

 Define void addCourse(Course course) method tdds the specifiedcourse to the end of the course list.

 Define Course find(String prefix, int number) that finds andreturns the course matching the specified prefix and number.

 Define void addCourseAfter(Course target, Course newCourse)that Adds the specified course after the target course. Doesnothing if either course is null or if the target is not found.

 Define void replace(Course target, Course newCourse) Replacesthe specified target course with the new course. The method doesnothing if either course is null or if the target is not found.

 Define String toString() method that creates and returns astring representation of this Program of Study as follows:

CS 101: Introduction to Programming [A-]

ARCH 305: Building Analysis [A]

FRE 110: Beginning French [B+]

CS 320: Computer Architecture

CS 321: Operating Systems

THE 201: The Theatre Experience [A-]

 Define class void save(String fileName) throws IOExceptionthat saves a serialized version of this Program of Study to thespecified file name.

 Define class ProgramOfStudy load(String fileName) throwsIOException, ClassNotFoundException that Loads a serialized Programof Study from the specified file.

POSTester Class

 POSTester program is attached with the assignment. You may useit to test your program.

POSTester.java

import java.io.IOException;

/**
* Demonstrates the use of a list to manage a set of objects.
*
* @author Java Foundations
* @version 4.0
*/
public class POSTester
{
   /**
   * Creates and populates a Program of Study. Then savesit using serialization.
   * @throws ClassNotFoundException
   */
   public static void main(String[] args) throwsIOException, ClassNotFoundException
   {
       ProgramOfStudy pos = newProgramOfStudy();

       pos.addCourse(new Course(“CS”,101, “Introduction to Programming”, “A-“));
       pos.addCourse(new Course(“ARCH”,305, “Building Analysis”, “A”));
       pos.addCourse(new Course(“GER”,210, “Intermediate German”));
       pos.addCourse(new Course(“CS”, 320,”Computer Architecture”));
       pos.addCourse(new Course(“THE”,201, “The Theatre Experience”));

       Course arch = pos.find(“CS”,320);
       pos.addCourseAfter(arch, newCourse(“CS”, 321, “Operating Systems”));

       Course theatre = pos.find(“THE”,201);
       theatre.setGrade(“A-“);

       Course german = pos.find(“GER”,210);
       pos.replace(german, newCourse(“FRE”, 110, “Beginning French”, “B+”));

      
       System.out.println(pos);
      
      pos.save(“ProgramOfStudy”);  
      
       ProgramOfStudy test =pos.load(“ProgramOfStudy”);
       System.out.println(test);
   }
}

If you could help that would be great.
