    Default toString method call issues

    Hi!

    I am having some issues in my very last function I am tasked with writing.

    It is using the toString() method to display the objects in an array that match only those from a specific class. For some reason, all I get when I execute the function is white space.

    Here's the code (it's a lot, sorry!):

    MAIN:

    Java Code:
    package assignment.pkg3;
    
    import java.util.Scanner;
    
    public class Assignment3 {
        
     //Function for user menu display and input
        public static int getMenuChoice()
            {
                Scanner keyboard = new Scanner(System.in);
                
                System.out.println("\n-----------------------------"
                + "\nHere are your Choices: \n"
                + "Enter 1 to add a Subscriber \n"
                + "Enter 2 to add an Application \n"
                + "Enter 3 to remove a Subscriber \n"
                + "Enter 4 to remove an Application \n"
                + "Enter 5 to display all Subscribers \n"
                + "Enter 6 to display all Applications \n"
                + "Enter 7 to Quit "
                        + "\n-----------------------------\n");
                
                return keyboard.nextInt();
            }
        
        public static void main(String[] args) 
        {
            Set<Element> anElementSet;
            Element anElement;
            Subscriber aSub;
            Application anApp;
            
            Scanner keyboard = new Scanner(System.in);
            
            int menuChoice;
            
            String search = "";
            
            boolean isDone = false;
    
            menuChoice = getMenuChoice();
            
            anElementSet = new Set<Element>();
            
            
            //Initiate loop to display menu
            while(!isDone)
            {
                 if(menuChoice == 7)
                {
                    System.out.println("Are you sure you want to quit? (Y/N)");
                    String askQuit;
                    askQuit = keyboard.nextLine().toUpperCase();

        {
            System.out.println("Here");
            if (theList.isEmpty())

             }
            else
            {     
                for (int i = 0; i < theList.size(); i++)
                {        
                   if(theClassName.equals(theList.getClass().getName()))
                   {
                       System.out.println(theList.get(i).toString());
                       System.out.println("\n");
                   }
                }
            }
        }
    Here's the specific line:

    Java Code:
     System.out.println(theList.get(i).toString());
    When I execute (making sure there are members in the set), it just does not print anything. I know it must be something with the way I'm attempting to execute the toString() method, but I am not sure why.

    Thank you for the help!

    all I get when I execute the function is white space.
    What does the output look like?
    Add some debug stuff to your printout:
    System.out.println("i=" + i + " data=" + theList.get(i).toString() +"<");

    Where is the defintion of the toString() method that is being called?

    Here's the debug code:

    Java Code:
    public void displayAllInClass(String theClassName)
        {
            System.out.println("Here1");
            if (theList.isEmpty())
             {
                System.out.println("Here2");
                System.out.println("There are no members in the set. ");
             }
            else
            {  
                        System.out.println("Here3");
                for (int i = 0; i < theList.size(); i++)
                {        
                            System.out.println("Here4");
                   if(theClassName.equals(theList.getClass().getName()))
                   {
                               System.out.println("Here5");
                       System.out.println("i=" + i + " data=" + theList.get(i).toString() + "<");
                               System.out.println("Here6");
                       System.out.println("\n");
                   }
                }
            }
        }
    Output:

    Java Code:
    -----------------------------
    Here are your Choices: 
    Enter 1 to add a Subscriber 
    Enter 2 to add an Application 
    Enter 3 to remove a Subscriber 
    Enter 4 to remove an Application 
    Enter 5 to display all Subscribers 
    Enter 6 to display all Applications 
    Enter 7 to Quit 
    -----------------------------
    
    5
    Here1
    Here3
    Here4
    So it looks like I was wrong, it's the if statement that's not executing:

    Java Code:
    if(theClassName.equals(theList.getClass().getName()))
    Sorry, for leading you down the wrong path, I remember debugging before and sincerely thought it stopped at that print line and not the if statement.

    Anyways, let's see here... I myself don't see anything wrong here.

    Java Code:
    theList.getClass().getName()
    Is pulling the name of the class from theList. And the function call:

    Java Code:
    anElementSet.displayAllInClass(Subscriber.class.getName());
    is ensuring that the name corresponds with what the user wants to display. A little confused here.

    Default Re: toString method call issues

    Ah okay. Well we've found the issue:

    I stuck in this snippet of code to find what you were asking for:

    Java Code:
    System.out.println(theList.getClass().getName());
    System.out.println(Subscriber.class.getName());
    System.out.println(Application.class.getName());
    Output:

    Java Code:
    java.util.ArrayList
    assignment.pkg3.Subscriber
    assignment.pkg3.Application
    So
    Java Code:
    theList.getClass().getName()
    is not referring to a class, instead it's referring to the name of the list itself (or utility, whatever it is). Why isn't the getClass method doing its job!?

    Sorry I'm not following which get method does what and what was printed and why it is not what you expect.
    Please post what method was used for each of the classnames/Strings you print out
    and add some comments to the post next to the output saying what you expected to be printed out.

    What do you expect getClass() to return? Then given that object, what do you expect the getName() method to return?
    What does the API doc say?

    Sorry, I want this function:

    Java Code:
    public void displayAllInClass(String theClassName)
    to print out all objects of the array, theList, that belong to either the Application or Subscriber class.

    What I expect this function to do:

    Java Code:
    if(theClassName.equals(theList.getClass().getName()))
                   {
                       System.out.println(theList.get(i).toString());
                       System.out.println("\n");
                   }
    is basically say this "If the string "theClassName" equals a specific class in the list (Subscriber or Application), then print out all objects associated with that class.

    As of right now,
    Java Code:
    theList.getClass().getName())
    does not do what I expected it to do (return either Subscriber or Application as the class name).

    I am unsure what I would use instead in its place.

    theList.getClass().getName())
    does not do what I expected it to do
    Can you show what it does do
    and add comments that show what you need or want?

    What class is theList? It looks like it's an ArrayList. So I'd expect getName() to return: java.util.ArrayList


    Are you wanting to look at the contents of the ArrayList?

    Default Re: toString method call issues

    This is what I expect:

    Java Code:
    if(theClassName.equals(theList.getClass().getName())) //return theClassName equals either "Subscriber" or "Application"
                   {
                       System.out.println(theList.get(i).toString());//print objects in list that belong to the class
                       System.out.println("\n");
                   }
    Java Code:
    theList.getClass().getName()
    currently returns java.util.ArrayList, as you said it would. I want something that returns an appropriate class name (Subscriber or Application).

    theList is an ArrayList.

    Do you want to look at the objects that are contained in the ArrayList?

    Yes I do want to look at the contents of the ArrayList and pull out any objects that belong to the specified class.

    For example, the function call:

    Java Code:
    anElementSet.displayAllInClass(Subscriber.class.getName());
    should search through the ArrayList and display ALL objects associated with ONLY the SUBSCRIBER class.

    Read the API doc for the ArrayList class to see what method to use to get a reference to an object in the ArrayList.
    When you get an object out of the ArrayList you can test it to see if it is the type of object you are looking for.

    The only methods I see that would be helpful are get() and indexOf(). Do these seem correct?

    I already have a method from my last program that uses indexOf to find the class name, but I cannot use that in my current program.

    Java Code:
    public String getClassName()
          {
             // Local data ...
             String resultStr;
             int whereAt;   // Where the . is in the class name
    
             // Logic ...
             resultStr = getClass().getName();
             whereAt = resultStr.indexOf('.');
             
             return resultStr.substring(whereAt + 1);
          }
    I don't understand how I can apply that logic to the ArrayList. Sorry for the ignorance, I am fairly new to Java.

    Default Re: toString method call issues

    How did you get the 300+ lines of code you posted?

    When not sure what a method for a class does, write a small test program, maybe 20 lines, and use the method to see what it does.
    Create an ArrayList, add some objects (Strings are easy) and then try both get() and index() to see what they do.

    Default Re: toString method call issues

    I wrote all of it minus the Set class and getClassName method which our instructor provided for us.

    I suppose I'm just drawing a blank, I will try everything I know of and see what works.

    Figured it out.

    Java Code:
    if(theClassName.equals(theList.get(i).getClass().getName()))
    Works fine, thank you.
