Alright, so I'm just working on the price method right now. It seems to go rather well until I get to the output. I get this bizarre thing that I'm sure many of you have seen before.
[Item@fabe9, Item@df6ccd, Item@601bb1, Item@1ba34f2, Item@1ea2dfe]
I looked up the odd outputs and was told that Arrays.deepToSt ring(arrays)); would help. Here is the method I'm working with. But as I print it out again...I still get...

I'm still trying to figure out just what I'm trying to do with this. This is what I started with:
...Code:public static void sortPrice(Item array[]) { int x; int j =0; Item temp; while (j < 5) { j++; for (x = 0; x < array.length; x++) { if(array[x].getPrice() > array[x+1].getPrice()) { temp = array[x];Leave a comment:

Yeah, I was having problems with my output and looking into ways of sorting it. I was hoping I wouldn't need a nested loop, but...I have to go with what works, right? I'll check Wiki.Leave a comment:

Is there anyway someone can take that last post out? The errors were completely my oversight. I put a lot of extra ;'s in there, but a nap and some coffee allowed me to wake up and see it.Leave a comment:

I'm still having error codes with that, even after taking the methods out of the main.
Errors:
CoffeeDriver.ja va:37: missing method body, or declare abstract
private static void sortPrice(Item array[]);
^
CoffeeDriver.ja va:41: cannot find symbol
symbol : variable array
location: class CoffeeDriver
for (x = 0; x < array.length; x++)

Alright, so now I have what I believe is a nice way to hold both pieces of the corresponding data under one [x].
Now my...Code:Item arr[] = new Item[5]; arr[0] = new Item("Coffee", 1.00); arr[1] = new Item("Water", 2.00); arr[2] = new Item("Milk", 1.50); arr[3] = new Item("Bagel", 1.25); arr[4] = new Item("Donut", 0.75);Leave a comment:

Thanks mate! This should keep me busy for the remainder of the night. It's nice to see some experts around here that are so willing to help. I'll keep you posted with the results!Leave a comment:

Oh! Another question...you mentioned that:
But I was under the impression that since I was getting it as user input that it was a String by default and that I should parse it to an int. That's why userInput and selectSort were so different.Code:9. // B 10. int selectSort; 11. // TODO: Use a JOptionPane to give selectSort the appropriate value
...Code:userInput = JOptionPane.showInputDialog(null,

Thank you, thank you, thank you! I think I see just what you're talking about now. And thank you for just explaining what I'm missing rather than showing me code. I don't want to get in trouble for that. I really want to write the code myself, not copy and paste. Let me try to revamp my code and I'll keep you updated. Hopefully, I'll be able to finish this quickly! So don't go far. Heh.

Now I'm a little less confused on what I need. Thank you! Now...how do I go about putting the item with the price in one array? And was I right to attempt to define the item objects in the constructor? I know, I sound like a really dim girl, but I'm doing my best to fully grasp the terms and how these concepts are applied, I promise. I really want to learn the basics of programming so I can move on to better things.Leave a comment:

Alright, I was actually giving this a shot to see what I could put together. I know, I'm missing a lot of the key elements, but so far, how does it look?
...Code:import java.util.Arrays import javax.swing.JOptionPane; public class CoffeeDriver { public static void main (String[] args) { String userInput; int x; int selectSort; String[] someItem = new String[5];Leave a comment:

I think I'm supposed to use two arrays for the project. Let me grab some of the criteria for you. I have started to put some of the code together, but I'm confused as to where I declare the array objects. Also, I was told that bubble sorting would be a good way to try this, but I've never used it. Can anyone give me information on that?
This project will require 2 classes. The first will be the data definition class and the second...Leave a comment:

Thanks so much, Anurag! This really helped me out. And it's something I hadn't read in my Java books yet.Leave a comment:

Actually, I don't think I'm that far in my Java yet. But what I did find was that I could loop the input and just parse it into a secondary array like this:
This way, I could...Code:for (x = 0; x < PLACE_HOLDER; ++x) { stringArray[x] = JOptionPane.showInputDialog(null, "Please input the price of the item you ordered."); doubleArray[x] = Double.parseDouble(stringArray[x]); }Leave a comment:

Beginner to Java: Constructors and Sorts
I am a beginner programmer and am having trouble with constructors and sorts. What's worse is that I am not used to programming in two different classes. It's making my head spin looking back and forth trying to trace the different names.
The idea behind the project is that I'm going to have two sets of arrays. One with item names and the other with the corresponding prices of said items. The user will be asked how they wish to... -
How do I create an array using user input?
I'm trying to create a program that prompts the user to put in several different numbers. I'd like to put those numbers into an array for easy use. To save me time on coding, I want to loop the request for user input. Would I use a for loop and use the subscript in the array to make changes as needed? Please help.
