Main Class and `main` Method:

This is the main class of the program, and it contains the `main` method that serves as the program's entry point. It sets up a menu-driven loop for interacting with surveys.

```java import java.io.IOException; import java.util.*; import java.io.*; public class Main { private static Survey currentSurvey = null; private static Scanner scanner = new Scanner(System.in); public static void main(String[] args) { while (true) { displayMainMenu(); int choice = scanner.nextInt(); scanner.nextLine(); // Consume newline left-over switch (choice) { case 1: createNewSurvey(); break; case 2: displaySurvey(); break; case 3: loadSurvey(); break; case 4: saveSurvey(); break; case 5: takeSurvey(); break; case 6: modifySurvey(); break; case 7: System.exit(0); } } } private static void displayMainMenu() { System.out.println("1) Create a new Survey"); System.println("2) Display an existing Survey"); System.out.println("3) Load an existing Survey"); System.out.println("4) Save the current Survey"); System.out.println("5) Take the current Survey"); System.out.println("6) Modify the current Survey"); System.out.println("7) Quit"); } // Other methods for survey operations } ```

The `main` method initializes a loop that continuously displays a menu and processes user choices until the user chooses to exit.

`displayMainMenu` Method:

This method displays the main menu options to the user.

```java private static void displayMainMenu() { System.out.println("1) Create a new Survey"); System.out.println("2) Display an existing Survey"); System.out.println("3) Load an existing Survey"); System.out.println("4) Save the current Survey"); System.out.println("5) Take the current Survey"); System.out.println("6) Modify the current Survey"); System.out.println("7) Quit"); } ```

This method is responsible for presenting the user with options for interacting with surveys.

`createNewSurvey` Method:

This method allows the user to create a new survey, adding questions of various types to it.

```java private static void createNewSurvey() { currentSurvey = new Survey(); // Add questions to the survey... boolean addingQuestions = true; Scanner scanner = new Scanner(System.in); while (addingQuestions) { System.out.println("Select the type of question:"); System.out.println("1. Add a new T/F question"); System.out.println("2. Add a new multiple-choice question"); System.out.println("3. Add a new short answer question"); System.out.println("4. Add a new essay question"); System.out.println("5. Add a new date question"); System.out.println("6. Add a new matching question"); System.out.println("7. Return to the previous menu"); int questionType = scanner.nextInt(); scanner.nextLine(); // Consume newline character if (questionType == 7) { addingQuestions = false; continue; } Question question; String prompt; switch (questionType) { case 1: System.out.println("Enter the prompt for your True/False question:"); prompt = scanner.nextLine(); question = new TrueFalseQuestion(prompt); break; case 2: System.out.println("Enter the prompt for your multiple-choice question:"); prompt = scanner.nextLine(); question = new MultipleChoiceQuestion(prompt); question.promptQuestionDetails(); break; case 3: System.out.println("Enter the prompt for your short-answer question:"); prompt = scanner.nextLine(); question = new ShortAnswerQuestion(prompt); break; case 4: System.out.println("Enter the prompt for your essay question:"); prompt = scanner.nextLine(); question = new EssayQuestion(prompt); break; case 5: System.out.println("Enter the prompt for your date question:"); prompt = scanner.nextLine(); question = new DateQuestion(prompt); break; case 6: System.out.println("Enter the prompt for your matching question:"); prompt = scanner.nextLine(); question = new MatchingQuestion(prompt); question.promptQuestionDetails(); break; default: System.out.println("Invalid question type. Skipping question creation."); continue; } currentSurvey.addQuestion(question); System.out.println("Question added successfully."); } } ```

This method handles the creation of a new survey by adding various types of questions (True/False, multiple-choice, short answer, etc.) to it.

`displaySurvey` Method:

This method displays an existing survey to the user.

```java private static void displaySurvey() { if (currentSurvey == null) { System.out.println("You must have a survey loaded in order to display it."); } else { currentSurvey.display(); } } ```

It checks if a survey is currently loaded and then displays its contents to the user.

`loadSurvey` Method:

This method allows the user to load an existing survey from a file.

```java private static void loadSurvey() { try { System.out.println("Please select a file to load:"); File surveysDirectory = new File("surveys"); File[] surveyFiles = surveysDirectory.listFiles(); if (surveyFiles == null || surveyFiles.length == 0) { System.out.println("No survey files found."); return; } // Display the menu of survey files for (int i = 0; i < surveyFiles.length; i++) { System.out.println((i + 1) + ") " + surveyFiles[i].getName()); } int choice = getUserChoice(surveyFiles.length); if (choice == -1) { System.out.println("Invalid choice."); return; } File selectedFile = surveyFiles[choice - 1]; currentSurvey = Survey.load(selectedFile.getName()); System.out.println("Survey loaded successfully."); } catch (Exception e) { System.out.println("Unable to load the file."); } } ```

The method provides the user with a list of survey files and loads the selected survey.

`getUserChoice` Method:

This method handles user input for selecting options or making choices.

```java private static int getUserChoice(int maxChoice) { int choice = -1; while (choice < 1 || choice > maxChoice) { System.out.print("Enter your choice: "); try { choice = Integer.parseInt(scanner.nextLine()); } catch (NumberFormatException e) { // User entered a non-integer value choice = -1; } } return choice; } ```

It ensures that the user's input is a valid choice within the specified range.

`saveSurvey` Method:

This method allows the user to save the current survey to a file.

```java private static void saveSurvey() { if (currentSurvey == null) { System.out.println("You must have a survey loaded in order to save it."); return; } System.out.println("Enter the filename to save the survey:"); String filename = scanner.nextLine(); try { currentSurvey.save(filename); System.out.println("Survey saved successfully."); } catch (IOException e) { System.out.println("Failed to save survey: " + e.getMessage()); } } ```

The method prompts the user for a file name and saves the current survey to that file.

`takeSurvey` Method:

This method allows the user to take a survey, record responses, and save them to a file.

```java private static void takeSurvey() { loadSurvey(); // Load an existing survey if (currentSurvey == null) { System.out.println("You must have a survey loaded in order to take it."); return; } int numQuestions = currentSurvey.getSurveySize(); List responses = new ArrayList<>(); for (int i = 0; i < numQuestions; i++) { Question question = currentSurvey.getQuestion(i + 1); question.display(); String response = scanner.nextLine(); responses.add(response); } try { String fileName = "responses/user" + (new Random()).nextInt(10000) + "_response.txt"; BufferedWriter writer = new BufferedWriter(new FileWriter(fileName)); for (int i = 0; i < numQuestions; i++) { writer.write(currentSurvey.getQuestion(i + 1).getPrompt()); writer.newLine(); writer.write("Response: " + responses.get(i)); writer.newLine(); } writer.close(); System.out.println("Responses saved successfully."); } catch (IOException e) { System.out.println("Failed to save responses: " + e.getMessage()); } } ```

It loads an existing survey, prompts the user for responses to each question, and saves the responses to a file.

`modifySurvey` Method:

This method allows the user to modify an existing survey by selecting and modifying a specific question.

```java private static void modifySurvey() { if (currentSurvey == null) { System.out.println("You must have a survey loaded in order to modify it."); return; } currentSurvey.display(); System.out.println("Please enter the question number to modify the question."); int questionNumChoice = getUserChoice(currentSurvey.getSurveySize()); if (questionNumChoice == -1) { System.out.println("Invalid choice."); return; } Question question = currentSurvey.getQuestion(questionNumChoice); question.modify(); } ```

The method displays the current survey and allows the user to select a question for modification.
