I feel as if I have gone over this code until my eyes are bleeding. I am missing something, and I cannot seem to locate my problem. I am supposed to use an array to store my items, my output should display my items one at a time, and should also display the value of the entire inventory. I have managed to eliminate all of my compiler errors, but my modifications are not showing in the output. Any assistance is greatly appreciated. Thank you!

Another student in your class posted on this forum not too long ago. At least I'm assuming that's the case, since you guys basically have the same exact program other than the movie names. Anyway, your problem is that you are overwriting your dvd in the Invent2 class.

edit: Nevermind. That was you. I can't really improve the advice that I gave you originally, but you did not follow it. To do this program, you should only need two classes: the class where you create the DVDs, and the DVD class. I already told you how to create a DVD and put it into the array:

public class DVD{
DVD[] dvds = new DVD[10];

public static void main(String[] args){
DVD dvd = new DVD(whatever);
dvds[0] = dvd;
DVD dvd2 = new DVD(aDifferentDVD);
dvds[1] = dvd2;
}

}

Okay, at least I'm not the only goob stuck on this! =) Thank you for the help BestJew! Have a great night.

Thanks, I'll change it back to the format that you helped me with before and try to go from there. What I don't understand is that everything in class Invent2 is displaying fine the way that I have it written now (perhaps changing the code to follow your advice will allow the new changes to display). Thanks, I really do appreciate you taking time to help me.

Every time you set dvd = new DVD(), you are overwriting what you previously put into dvd. Again, consider this example:

DVD[] allMovies = new DVD[10]; -- This statement creates an array big enough to hold 10 DVDs.

DVD movie = new DVD(lionKing); -- This statement creates a new variable of type DVD called "movie". It then puts the DVD lion king into the movie variable. (What it actually does is a bit more complex, but this is what it amounts to)

movie = new DVD(granTorino); -- Now we just put gran torino into the movie variable. So where is lion king now? Nowhere.

From where you're currently at, there really isn't much need to erase everything. You just need to put an array in the Invent2 class, then add each dvd to the array after you create it.

Invent2{

//declare an array of DVDs here

main method(){
dvd = new DVD(1, "Pulp Fiction", 8, 12.99);
array[0] = dvd;
System.out.println(dvd);

dvd = new DVD(2, "Resevoir Dogs", 9, 12.99);
array[1] = dvd;
System.out.println(dvd);
}

}

The reason I said you didn't need three classes is because the Inventory class isn't really necessary. You can take all the code you were going to put in Inventory and put it in Invent2 instead. Since all the Inventory class does is contain an array that holds your DVDs, it makes more sense to combine this with the other class.

Also, I apologize if I confused you with my multiple posts. I'm kind of tired and at one point I briefly gave you incorrect information, although I don't think you saw this information (as it was only there for a minute or two).

The following is my complete code as of now. I am recieving a compiler error that I cannot track down. The error is at line 105:
} // end class Inventory2. The error message is the " class, interface, or enum expected". I do not find any open or missing braces, does anyone else see the problem? Thanks.

You still have a lot of errors.

  1. The "main" method should be declared as public static void main(String[] args), and this declaration should never be changed to something else. The reason is because it is just a standard that main is the method which will run when you start the program, so changing it's usual declaration is confusing.

  2. You said DVD[] DVD = items, which might work, but does not make sense. Delete it, and instead of saying DVD[0] = whatever, say items[0] = whatever.

Change those couple things and then tell me what errors you are getting. And re-post your code using the Java code tags. To do this, just click everything you normally would, but then when it says (CODE) change it to (CODE=Java) (only for the first CODE tag)

Edited 3 Years Ago by mike_2000_17: Fixed formatting

I changed main back to public static void(String[] args), deleted
DVD[] DVD = items, and changed the instances of DVD[0] (DVD[1], DVD[2]...) to items[0], and I now have 45 errors. I am just freaking lost here... here is my code ( I apologize for not formatting correctly earlier).

Error 1: The DVD class does not have a method called getItemValue, hence the error. You have to write the method.

Error 2: This isn't actually an error. Once you correct the previous error, it will go away, I believe.

Thank you for the encouragement, and the help. I was so frustrated that I scrapped my original and started over from scratch. This time I referred to my text at every turn, and my code came out looking quite a bit different than before. Now it compiles and runs (it seems like I have compiled this code hundreds of times now), but one of my new additions, a 5% restocking fee is not displaying. I have been rewriting this code for over a day now, and my eyes could be the problem! I would appreciate any input on the restocking problem. Thanks!

I'm personally very busy right now, so i apologize if you knew this already, but you are calling the method from your parent class when you use super.getValue() . . not the method from the class you are in. I just don't see a reason why you'd want to do that, considering you overrode the getValue method, is why I even mention it.

Great explanations and help! Problem solved!

Hi Folks!
BestJewSinceJC has helped me solve my problem, and I would like to give him credit for that. The problem is that I can't find any way to mark this as "solved". Could someone help me out?

You can mark the thread as solved by clicking the link at the bottom of the thread that says "mark as solved". It should be a blue link underneath the very last post, next to the yellow button that says 'Reply to Thread'. Basically, it's just a way for the person who originally created the thread to acknowledge everyone who posted in it. It's also helpful because then people will know the thread is solved. If you can't find it though, or if for some reason it isn't there, don't worry about it, its no big deal. To me, its cool just to know that I was able to help someone solve their problem and learn more programming in the process
