Add a menu loop that: Displays the (included) menu Prompts the user for input and validates the input Takes the appropriate action based on the input

Question

Below are the directions and the code I have so far. I am not sure where I am going wrong but I know that my loop isn't right. Will you please help me? In a new Java file, create the Monkey class, using the specification document as a guide. The Monkey class must do the following: Inherit from the RescueAnimal class. Implement all attributes to meet the specifications. Include a constructor. You may use a default constructor. To score “exemplary” on this criterion, you must include the more detailed constructor that takes all values for the attributes and sets them. Refer to the constructor in the Dog class for an example. Include accessors and mutators for all implemented attributes.

In the Driver.java class, modify the main method. In main(), you must create a menu loop that does the following: Displays the menu by calling the displayMenu method. This method is in the Driver.java class. Prompts the user for input Takes the appropriate action based on the value that the user entered

import java.util.ArrayList;
import java.util.Scanner;

public class Driver {
    private static ArrayList<Dog> dogList = new ArrayList<Dog>();
    private static ArrayList<Monkey> monkeyList = new ArrayList<Monkey>();
    // Instance variables (if needed)

public static void main(String[] args) {displayMenu();
    Scanner scnr = new Scanner(System.in);
    String displayMenu = scnr.nextLine();
    String menu_option = scnr.nextLine();
    initializeDogList();
    initializeMonkeyList();
    do {
        displayMenu();
        if(menu_option != "q") {
            System.out.println("\t\t\t\tRescue Animal System Menu");
        }
        else if(menu_option == "1") {
            System.out.println("[1] Intake a new dog");
        }
        else if(menu_option == "2") {
            System.out.println("[2] Intake a new monkey");
        }
        else if(menu_option == "3") {

    // Add a loop that displays the menu, accepts the users input

    // and appropriate feedback to the user.

Answer 1

The issue with your code is that while your loop is working fairly well, it has no while section at the end. Your code within the while loop also seems to only print the menu option instead of doing anything. I'd say the best thing to do would be to call the displayMenu() method with displayMenu(); at the beginning of the do loop then finish the loop with }while (.input.equals("q"))

Answer 2

In regards to your Monkey class, remember it is extending from the RescueAnimal class. So you do not need to redo the same setters/getters from the RescueAnimal class. All you need are the Monkey specific attributes.

public class Monkey extends RescueAnimal {
    private String species;
    private String tailLength;
    private String height;
    private String bodyLength;

public Monkey(String species, String tailLength, String height, String boydLength) { 
            setSpecies(species);
            setTailLength(tailLength);
            setHeight(height);
            setBodyLength(bodyLength);
    }

public String getSpecies() {
    return species;
}

public void setSpecies(String species) {
    this.species = species;
}

public String getTailLength() {
    return tailLength;
}

public void setTailLength(String tailLength) {
    this.tailLength = tailLength;
}

public String getHeight() {
    return height;
}

public void setHeight(String height) {
    this.height = height;
}

public String getBodyLength() {
    return bodyLength;
}

public void setBodyLength(String bodyLength) {
    this.bodyLength = bodyLength;
}

}

And for your driver class, remember a do/while loop only works when both are utilized. So DO this, WHILE this condition is met.

import java.util.Scanner;

public class Driver {
    private static ArrayList<Dog> dogList = new ArrayList<Dog>();

    initializeMonkeyList();
    
    Scanner input = new Scanner(System.in); // scanner class object
    char option;
    
    do // loop until user exits application
    {
        displayMenu();
        option = input.next().charAt(0);
        if (option == '1') { // intakeNewDog method is called
            intakeNewDog(input);
        }
        
        else if (option == '2') { // intakeNewMonkey method is called
            intakeNewMonkey(input);
        }
        
        else if (option == '3') { // reserveAnimal method is called
            reserveAnimal(input);
        }
        
        else if (option == '4') { // printAnimals method is called to print the dog list
            printAnimals(option);
        }
        
        else if (option == '5') { // printAnimals method is called to print the monkey list
            printAnimals(option);
        }
        
        else if (option == '6') { // printAnimals method is called to print all available animals
            printAnimals(option);
        }
        
        else if (option == 'q') { // exit message prints and application stops running
            System.out.print("You have exited the application.");
            break;
