Solved-Project 5 -Solution

Description

Background

The University of Florida English department has asked you to create an autograder for its introductory class. There are many types of students who are taking this class. Some are high­achieving High School students, some are University of Florida Undergraduate students, and some are Graduate students who need a refresher. They would like to create a parent (base) Class that can be extended to provide functionality for various kinds of students. The department has specifically asked for the ability to supply the name of the file containing a student’s essay (the student’s’ ID number.txt) and have the program grade the essay, by listing all the misspelled.

Objective

• Read in the file given

• Store each misspelled word

• List all misspelled words

• Generate an output file that contains the student’s graded feedback

Your Assignment

You will need to create five files complete this project and name them exactly as follows: Project5.java, Student.java, HighSchoolStudent.java, UndergraduateStudent.java, GraduateStudent.java, Dictionary.java, Grader.java.

The Project5.java and Student.java files have been provided, and it’s your responsibility not to modify them. If you modify them, you will most likely fail the grading

program. Each of the .java files and their associated classes are described as below:

Project5.java (Do not modify, or you will fail the grading)

The Project5 Class will hold the main method of your program. We have already implemented that for you. Generally, it will:

• ask you to input the dictionary name

• load the dictionary

• Grade the students’ essays (in a loop) based on the student ID (input from the keyboard).

• Terminate when “exit” is typed in for student ID.

Do not modify this class. It provides you an entry point and a skeleton from which to start your project. If the other five required classes have not been correctly implemented, it’s highly possible that your program will fail to compile.

Also, you can add your own methods in addition to the mandatory methods and fields in the five required classes. Please do not change the method signature to handle exceptions. You should surround any code that may throw an exception in a try/catch block. The exceptions should not be raised to the main method.

Dictionary.java

The dictionary class will load the dictionary from a dictionary file, and be used to check misspellings. The class must have the following members with the exact same signatures:

• A data field to hold the words from the dictionary

• • private ArrayList<String> dictionary = new

ArrayList<>();

• A method that returns the number of words in the loaded dictionary

  • public int getVocabularySize()

• A method which will load the dictionary file based on the file name. You may assume the dictionary file is in the same folder as the Dictionary class. If loading the dictionary succeeds (meaning that the file was found), return true. Otherwise return false.

• • public boolean loadDictionaryFromFile(String

filePath)

• A method which being used to check whether a given word is in the dictionary. If the word is in the dictionary, return true, otherwise return false. In the essay, a word is considered a series of letters, separated by spaces. As long as the word, exactly as given, is found in the dictionary, we will consider it to be correct. If a word is not in the dictionary, it will be considered as a misspelling. For example, if you pass in the word “cat’s”, you will see that “cat” is in the dictionary, however “cat’s” is not. In this case, “cat’s” will be considered as misspelling. Please follow this rule. DO not make up your own rule.

• • public boolean isWord(String word)

Grader.java

• • public String getPrintableErrorList()

• An abstract method being used to write the graded files to file system, which you are supposed to implement in all the subclasses

• • public abstract void writeToFile()

• A constructor

  • public Student(String name, String id, String essay, ArrayList<String> errorList)

HighSchoolStudent.java

The HighSchoolStudent class is a child class of the Student Class. The class must have the following members with the exact same signatures:

• Fields for the following attributes

• • private String nameOfSchool

• “getter” and “setter” methods

  • public String getSchoolName()

  • public void setSchoolName(String schoolName)

• A method implements the abstract method in parent class, which will write the student’s grading information to the file.

• • public void writeToFile() ­

• • • The file should be in the same path as all class files.

    • The file name should be named id+”_graded.txt”. e.g. if the

student’s id is “12345678”, the generated file name should be “12345678_graded.txt”

• In the file, the content should be written as following sequence: (suppose the student’s name is FName LName, id is 12345678, school name is Gainesville High School)

• • High School Student FName LName

  • Student ID: 12345678

  • School Name: Gainesville High School

  • (1)errwrod1

  • (2)erword2

• • • How to define error words will be discussed in Grader class.

• • • Hint: use public String getPrintableErrorList() method in parent Student class to format the error words output.

    • Important: you should handle all exceptions inside the method. DO NOT throw any exception throw the method, or the mandatory signature will be changed. You should enclose the code that may throw the exception within a try/catch block.

• A constructor

• • The constructor must initialize all fields of the Student object, using the constructor’s parameters

• • • HighSchoolStudent(String name, String id, String essay, ArrayList<String> errorList, String nameOfSchool)

Submission Requirements

● Zip all seven Class files Project5.java, Student.java, HighSchoolStudent.java, UndergraduateStudent.java,

GraduateStudent.java, Dictionary.java, Grader.java and your extra classes into one single zip file without any folder hierarchy. For verbal and pictorial instructions on how to do that, please refer Project 4 submission requirements.

• The zip fileshould be named project5_ulfid.zip where uflID is the alphanumeric portion of your ufl email account that comes before the @ufl.edu part.

• Submit on time using Canvas

Notes

• When inputting essay files and generating graded output files, make sure they are in teh same folder as all your class files.

• If your zip file is not named project5_ulfid.zip, your project will not be graded.

• If you do not name the items above exactly as specified, where specified, your project will not be graded correctly.

• Please convert both the dictionary words and essay words to

lowercase and remove all punctuation except the apostrophe (‘) and hyphen (­) during word comparison.

• It is highly recommended that you test your program piece by piece before assembling your final code. You will have a much easier time if you build your program piece by piece rather than trying to write the entire program. If you have

more questions about the project, it is highly recommended to consult your TA at office hours.

• Please make sure to mimic the output in the Sample Runs, and your output should be the same as the one in the Sample Runs. More importantly, your file output should follow the format described previously. The grades will be decided by those output files and the implementation of mandatory methods/classes.

• Some, unit testing will be made available for this project. You will still need to compare your output file to the correct output.

Grading

• 100% of your grade will be based on your program’s ability to generate proper output (files) and using all of the mandatory methods.
