    Default Another probably very simple concept I am having trouble with :(

    Hey guys, I am working on an assignment, I have already finished the first portion of it, but I am having trouble figuring out how to get the last part to work properly.

    The syllabus is asking that we:
    Modify the Inventory Program so the application can handle multiple items. Use an array to store the items. The output should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the output should display the value of the entire inventory.
    • Create a method to calculate the value of the entire inventory.
    • Create another method to sort the array items by the name of the product.

    I am having issues with the final portion of the assignment, of creating a method to sort the array items by the name of the product.

    From using my existing code, if I attempt to create a separate method for that, I get a null pointer exception, although Netbeans shows no errors before trying to compile it.

    Here is the original code:
    Java Code:
    package dvdinventory;
    
    
    public class displayInv {// Class for displaying the data within the program.
    
        
      int [] dvd;//Array for the DVD info.
    
    
    String [] title;// Array for setting the title of the DVD.
    
    
    
        public void setInfo(){// Method to perform the actions of the program.
    
            title = new String [4];//Initializing the Array
            title[0]= "The Social Network";// Setting the first element of the array for the DVD title.
            title[1] = "Hackers";// Setting the second element of the array for the DVD title.
            title[2] = "Anti-Trust";// Setting the third element of the array for the DVD title.
            title[3] = "Takedown";// Setting the fourth element of the array for the DVD title.
            
            dvd = new int [17];//Initializing the array.
            //Elements for The Social Network.
            dvd[0]= 2121;// Setting the element for the Stock number of the DVD inventory of The Social Network.
            dvd[1]= 25;// Setting the element for the price of the DVD in the array.
            dvd[2]= 50;// Setting the element for the amount in inventory in the array.
            dvd[3]=dvd[1]*dvd[2];// Setting the element for the total price of the inventory within the array.
            //Elements for Hackers.
            dvd[4] = 2122; //Stock;  Setting the element for the Stock number of the DVD inventory of Hackers.
            dvd [5] = 20; // Price; Setting the element for the price of Hackers.
            dvd [6] = 40; // Inventory; Setting the element for the amount of Hackers DVDs in stock.
            dvd [7] = dvd[5]*dvd[6]; // Total; Setting the element for the total price of the Hackers inventory.
            // Elements for Anti-trust.
            dvd [8] = 2123; // Setting the element for the stock number of the DVD inventory of Anti-trust.
            dvd [9] = 15; // Setting the price of the DVD Anti-trust.
            dvd [10] = 38; // Setting the amount of Anti-trust DVDs in stock.
            dvd [11] = dvd[9]*dvd[10]; // Setting the amount of the total inventory of Anti-trust.
            // Elements for Takedown.
            dvd[12] = 2124; // Setting the element for the stock number of the DVD inventory of Takedown.
            dvd[13] = 12; // Setting the element for the price of the DVD Takedown.
            dvd[14] = 50; // Setting the element for the total amount of Takedown DVDs in stock.
            dvd[15] = dvd[14]*dvd[13]; // Setting the element for the total price of the inventory Takedown.
            // Total inventory
    
    
    
    
            // The social Network
            System.out.println("This is an inventory of the DVD " +title[0]+ ", stock number:"+ dvd[0]);// Displays the name and stock number of the DVD.
            System.out.println("The amount of DVD's in stock is:"+dvd[2]);//Displays the amount of DVDs in stock.
            System.out.println("The price of each DVD is :$"+dvd[1] +".00");// Displays the price of each DVD.
            System.out.println("The total amount of inventory is:$"+dvd[3]+".00");// Displays the total cost of the entire inventory of DVDs in stock.
            System.out.println("");
            // Hackers
            System.out.println("This is an inventory of the DVD " +title[1]+ ", stock number:"+ dvd[4]);// Displays the name and stock number of the DVD.
            System.out.println("The amount of DVD's in stock is:"+dvd[6]);//Displays the amount of DVDs in stock.
            System.out.println("The price of each DVD is :$"+dvd[5] +".00");// Displays the price of each DVD.
            System.out.println("The total amount of inventory is:$"+dvd[7]+".00");// Displays the total cost of the entire inventory of DVDs in stock.
            System.out.println("");
            //Anti-Trust
            System.out.println("This is an inventory of the DVD " +title[2]+ ", stock number:"+ dvd[8]);// Displays the name and stock number of the DVD.
            System.out.println("The amount of DVD's in stock is:"+dvd[10]);//Displays the amount of DVDs in stock.
            System.out.println("The price of each DVD is :$"+dvd[9] +".00");// Displays the price of each DVD.
            System.out.println("The total amount of inventory is:$"+dvd[11]+".00");// Displays the total cost of the entire inventory of DVDs in stock.
            System.out.println("");
            //Takedown
            System.out.println("This is an inventory of the DVD " +title[3]+ ", stock number:"+ dvd[12]);// Displays the name and stock number of the DVD.
            System.out.println("The amount of DVD's in stock is:"+dvd[14]);//Displays the amount of DVDs in stock.
            System.out.println("The price of each DVD is :$"+dvd[13] +".00");// Displays the price of each DVD.
            System.out.println("The total amount of inventory is:$"+dvd[15]+".00");// Displays the total cost of the entire inventory of DVDs in stock.
            System.out.println("");
            
    
    }// End Method
    
        public void calcTotal(){// total inventory
    
    
            dvd[16] = dvd[15]+dvd[11]+dvd[7]+dvd[3];
            
            System.out.println("The total worth of the current inventory is:$"+dvd[16]+".00");// Displays the total worth of the entire inventory.
    
    
        }//End Method
        
    }// End Class
    It actually compiles and runs fine

    And the code with the error:

        }//End Method
        
    }// End Class
    I just cannot wrap my head around what I am supposed to do to get the second method that the assignment calls for.

    Any help is greatly appreciated.

    Are you using classes in your class yet? If you are, I suggest you make a class, and sort the class. Otherwise you will have to sort the array with the titles, than sort each other array so they match the title array. This will be extremely confusing and difficult for a beginner.

    If you made a class like this
    Java Code:
    class DVD{
      String title;
      int price;
      //other variables you may want
      //constructors
      //other methods
    }
    Managing an array of DVD objects will be infinitely easier than managing parallel arrays as you are doing now. With this you can build the sort into the DVD class(look up comparable/comparator).

    To sort an array of DVD's you would only have to do
    Java Code:
    Arrays.sort(dvdArray);
    And it will be sorted for you.

    Basically, create a class to hold all the information about the item you want to represent. From there you can create objects of that type, and create an array, like this
    Java Code:
    DVD[] dvds = new DVD[10];
    Then you can fill the array with dvd objects, like this
    Java Code:
    DVD socialNetwork = new DVD("Social Network", 10, 10); //you may have other arguments
    dvdArray[0] = socialNetwork;

    "Modify the Inventory Program" suggests that this code is based on something you already turned in for another assignment. If that's the case, then I'm shocked and appalled that your instructor didn't stop you then and explain object-oriented programming, or even simple procedural concepts like loops. :(

    @op: To help you out some more, I thought I would explain what makes parallel arrays so challenging.

    Lets say you have the two parallel arrays, one represents a number, and the other has a number associated with it

    Java Code:
    String[] names = {"Apple, "Fig", "Orange", "Grape"};
    int[] prices = {10, 15, 5, 3};
    In this above example, apple is 10 cents, fig is 15, orange is 5, and grape is 3. Lets say we want to sort the fruits by name, and we want the prices to still reflect the sort. This would be easy for a small collection of data, in our head.
    Java Code:
    String[] name = {"Apple", "Fig", "Grape", "Orange"};
    int[] prices = {10, 15, 3, 5};
    This is easy enough. But how would you tell the computer to recognize this? How does the computer know the price of the apple, or fig? They are stored independently of each other. Changes to apple don't effect the change of the values in the price array. You could manually sort a small array with a method I suppose, but this is something you should avoid. What's the point of having a computer if you are going to do something manually like that?

    Imagine the DVD example, where each dvd has 4-5 parallel arrays, that alone will make manual coding even more difficult, now imagine if you arrays suddenly have 1000 items each. The method would be come nearly impossible, and incredibly impractical.

    I am sure you are wondering "But what do I do then? I need to do this, it's an assignment". There are two approaches, one won't work for the DVD class. One is to use an associative container, which associates one value with another. In Key value pairs. The items are linked together. These are usually Maps, lets look at the fruit example.

    Java Code:
    Map<String, int> fruits = new HashMap<String, int>();
    fruits.put("Apple", 10);
    fruits.put("Orange", 15);
    fruits.put("Fig", 4);
    This is a better way of handling it, but not always a workable situation, especially in the DVD assignment.

    With this if you sort the Map it keeps the int, and the string linked together. If the position of the apple changes, it still knows how to find the int. I won't get too in detail with maps, since it wont help your problem. However, to read more on it, check out this. http://download.oracle.com/javase/tu...faces/map.html


    Since neither of these approaches are really suitable, you want a class, which encapsulates ALL the information for you, and is great for "gluing" multiple things together. Lets create a fruit class, which has a name, price, weight, and color.
    Java Code:
    class Fruit{
      private String name;
      private int price;
      private double weight;
      Color color;
    }
    This is a very basic representation of a fruit class. You will be adding many more things, including getters and setters. These allow the outside world to modify your classes data. Contructors- allow instances of an object to be created, and other methods to do stuff.

    Java Code:
    class Fruit{
      //instance variables
      public Fruit(){ //default constructor
      }
      public void setName(String name){
        this.name = name;
      }
      public String getName(){
        return name;
      } 
      //other getters/setter, all have similar form and names
      //other methods
    }
    Now, you can create a list of objects
    Java Code:
    Fruit[] fruits = new Fruit[1];
    fruits[0] = new Fruit("Apple", 10, 10.0, Color.RED);
    That constructor doesn't exist, you would create your own constructors that use arguments to create the object.

    Now you can sort the array by object, and look at the object and extract information.

    You can even override a method called toString, which returns a string and allows for easy printing.
    Java Code:
    class Fruit{
    stuff..
      public String toString(){
        return "Fruit name: " + name + "\nFruit price: " + price + "\nFruit Weight: " + weight + "\nFruit Color: " + color;
      }
      other stuff..
    }
    Now you can simply do
    Java Code:
    Fruit f = new Fruit();
    System.out.print(f);
    and it will print the details of your fruit.

    This is a lot of teaching, for more detail, check out the classes tutorial.
    http://download.oracle.com/javase/tu...O/classes.html

    I know this is a lengthy post, however; I believe it should help you quite a bit.

    Sunde thank you, I will try what you are describing and see what I can come up with.

    Kjkrum, its an online class, basically teaching myself some instructors are very helpful, but this one just refers us back to the sun java tutorials with any questions. The problem with going to school while working a full time job, I cant manage a regular schedule.

    I have read the book, have bought other books, watched videos on youtube and itunes, anything I can to figure this out on my own.

    I know the code isnt pretty by any means, but its the best I have been able to come up with. The prior assignment is basically the first code I pasted.

    So this:
    Java Code:
    DVD socialNetwork = new DVD("Social Network", 10, 10); //you may have other arguments
    dvdArray[0] = socialNetwork;
    Actually does the first part of what I was trying to do in the origional program? It would set the Title, price, inventory, ect.. all in that single line, then the array creates an object socialNetwork that has all of that information contained within it?

    Am I following or way off base?

    You are pretty close. The first line creates an object, and sets all the variables of it for you. Then it stores that variable in an array. You can retrieve that element and treat it like an object of the array type(call methods etc)

    Lets assume you have a array filled with arrays, you can then print it VERY easily, like this
    Java Code:
    for(int  i = 0; i < dvdArray.length; ++i){
      System.out.println(dvdArray[i];
    }
    Those three lines and an overriden toString method can print an array for you. It will greatly simplify things.

    Work on building the class FIRST. Post what you come up with here and I can help you move on/fix what's incorrect. Also, your teacher is referring you to the tutorials because they are quite invaluable. They are designed by people incredibly skilled with java and they contain lots of thorough explanations and good example code to play around with.

    Thank you again Sunde, I will work on creating the class and everything, and post my progress as it is made.

    Sadly it will have to be later on, work comes very early, but I wanted to thank you again for offering to help.

    I know how work is, it sucks, I wish I could spend a lot more time reading. I get a few books a month, and don't read at the same rate I get them. I have like 15 books right now that I intend to read, and another on the way lol.

    It may be a lot of work to create the class and start the program over, but it will make your work easier in the end. Sorting, printing, and any general maintenance of the list will become incredibly simple. It will also, hopefully, teach you a decent amount about oop, and you can keep this in mind during later projects/assignments.

    Ok, Im trying starting from scratch, this is the code that I have thus far:

    Java Code:
    package dvdinventorywk6;
    import java.util.*;
    
    /**
     *
     * @author erikd
     */
    public class dvdinventorywk6 {
    
        
        public static void main(String[] args) {
           dvd titlesort = new dvd();
           titlesort.sortInfo();
        }
    
    }
     class dvd {
        String title[] = {"The Social Network", "Hackers","Anti-Trust"};
    
    
         public void sortInfo(){
           
             for (int i = 0; i <title.length; i++){
                 
             System.out.println(title);}
             Arrays.sort(title);
              
              
    
         }
    
    
    }
    The weird thing is, it compiles fine, no errors, but I get this as the output:
    run:
    [Ljava.lang.String;@1d5ee671
    [Ljava.lang.String;@1d5ee671
    [Ljava.lang.String;@1d5ee671
    BUILD SUCCESSFUL (total time: 0 seconds)

    With no errors to work with, Im kinda lost, any suggestions as to what I am doing wrong? This is just the first part of the assignment, I think if I can get this part to working right, I can apply the same concepts to doing the rest of the assignment.

    You didn't override toString so it uses the object classes toString, which returns all that gobbledegook, which is the class name @ hex hash code.
    Also, you want to make the DVD class more generic, don't hard code the title, it also should have an array, instead a DVD should look like this

    Java Code:
    class DVD{
      private String name; 
      private double price;
      private int quantity; 
      ... More instance variables if necessary
    }
    The tutorials should have an example of building and using a class.

    Thank you for the reply. This is honestly making the sick, because you are mentioning things that have not been discussed or demonstrated at all, and it seems they should have.

    Im completely lost right now, so gonna try and find some videos that explain this stuff more.

    thank you again for the reply, ill keep you updated on the progress

    I highly suggest reading this Classes (The Java™ Tutorials > Learning the Java Language > Classes and Objects)
    It's explains everything quite well and it should have working example code that you can "mimic" when making the DVD class.

    In this assignment you want to start small and work your way up. You start with the smallest item an inventory contains, in this case, a DVD. You create a class that represents an image. A class is like a blueprint, much like a houses blueprint, it shows how a house is made, but doesn't actually make it. You use the blueprint to make houses.

    In oop you use the class to make objects of that class.

    The next piece you want to make is an inventory; which represents an inventory of items, so it basically manages an array of DVD objects.

    When you said I didnt override toString, what exactly did you mean? I have been googling this for a while now, and it is escaping me.

    This is the first link that Google gave me when I Googled, "How to override toString of Object class" : Overriding toString()

    You can cross check that with Google search :p

    Hope that helps,

    Heh, like I said, it was escaping me, I had been reading on it, but some things need to be "dumbed down" for them to click with me hehe. I finally figured it out, thanks for the link though :)

    Always remember, this gobbledegook: ClassName@186af6d means that the object toString method was called and your error lies in printing, either you tried to print an array or you didn't give the class an overridden version of toString.

    I sleep really weird hours, I work midnights 3 days a week and today I work a midnight and then a 3-11 shift. On my days off my schedule is so messed up I usually stay up all night. My job is slow so I browse the forums for new stuff on my phone a lot.

    I do a lot of reading at work, wish is could bring a laptop, I get a very good theoretical knowledge of everything but my practical side isn't where I'd like it. Helping here also let's me see a lot of common errors to be aware of and it helps me to keep constantly re hashing information.
