Inventory Program - Add / Delete / Modify / Search And Save
Feb 15, 2015
The goal was to add a few buttons an add delete modify search and save. I feel like I have the entire need satisfied. I'm having a few symbol problems which I'm not quite sure how to fix.
My full code is:
import javax.swing.*;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.awt.event.*;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
[Code] ....
which is directing me towards Prodname on the far right of the if statement. I'm not sure what the problem is. I've double checked my spellings several time for each spot and I cant quite get it.
Everyone has told me but I am aware that I made some bad decisions with the variables being capitalized this was my first go at a program and my instructor didn't let me know that thats the normal way to do it.

I am writing a program for my Java class and I have every function of the program working aside from the modify and delete button. I'm not sure how to make them work. The course material doesn't cover these functions at all.
Here is what I have so far.. which is practically nothing. If I need to post any other code I will, I just don't want to post more than needed because going through unnecessary code can waste time.
public void actionPerformed(ActionEvent e)
{
inventoryTotalField.setText(String.valueOf(genre[ArrayIndex].getInventoryTotal()));
//add button functions
if (e.getActionCommand() == "First")//if first button is clicked
{
ArrayIndex = 0;//set array index to the first element in the array
setFieldValues(); // display dvd info on the form
[Code] .....

for my assignment I am to only add the sort and total inventory methods in the inventory class. And not create an array in the inventory class at all. My inventory class should contain all the variables needed to use with the two new methods: sort and calculate total inventory.By not creating any array in the inventory class and not touching the variables at all.
What I have came up with is:
public class inventory
{
private int prodNumber; // product number
private String prodName; // product name
private int unitsTotal; // total units in stock
private double unitPrice; // price per unit
private double totalInventory; // amount of total inventory
// initialize four-argument constructor
[Code] ....
The error message I get is:
F:Java Programminginventory.java:62: error: cannot find symbol
return prodName.compareTo ( s. getprodName() );
^
symbol: method getprodName()
location: variable s of type inventory
1 error

Is there a way that I can save a binary search algorithm to a text file or something, so that it will always contain more information? The reason why I ask this is because I have BST like project which is supposed to act the game Twenty Questions, were it asks a person 20 Q's until it guess the answer. However, although my project does not require you to save stuff to a file, I find it rather very useful and cool if I could do that.So for example it would start out something like this:
Think of an animal and I will guess it.
Does it have legs? YES
Is it a cat? YES
I win! Continue? YES
Think of an animal and I will guess it.
Does it have legs? NO
Is it a snake? YES
I win! Continue? YES
Think of an animal and I will guess it.
Does it have legs? NO
Is it a snake? NO
I give up. What is it? EARTHWORM
Please type a question whose answer is yes for an earthworm and no for a snake.
DOES IT LIVE UNDERGROUND?
Continue? YES
Think of an animal and I will guess it.
Does it have legs? NO
Does it live underground? NO
Is it a snake? NO
I give up. What is it? FISH
Please type a question whose answer is yes for an earthworm and no for a snake.
DOES IT LIVE IN WATER?
Continue? NO
Good-bye.
However, if the user exits the program then everything will be lost and go to waste. So once again, is there a way that I can save all of these inputs to a file or something and then read it in again?

My instructor gave me this code to use as my Array sort. I can not get this to work. I do not get any compile errors, the code just does not do anything.
Java Code:

I am trying to create a GUI with already existing code. My assignment is: Modify the Inventory Program to use a GUI. The GUI 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 GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.
Where to start. The text book does not cover a GUI that displays this type of information rather it just displays graphics. I would like to create a separate class that holds the GUI information just to make everything flow better. I have provided my current code below:
Java Code:
// ProductTest.java
// by JakeB
public class ProductTest {
// main method begins
public static void main(String[] args) // begin main {
myGUI display = new myGUI();
display.setVisible(true);
[Code] .....
This is all I have for the GUI. I am at a total loss and I am behind 2 weeks now. I cannot move forward until I am able to get this done and the class ends next week.

I am stumped on a coding project I am working on. I am making an inventory program with predefined values for the items. I am not sure how to iterate through my arrayList, and allow the user to input the "number sold."
I have made an arrayList and populated it using the add(), but I am not sure if it is working correctly. This is my inventoryItem class :
package inventory;
import java.text.DecimalFormat;
public class inventoryItm {
String itemName;
double unitPrice;

I'm working a an assignment for my IT/215 class and I'm having a little trouble with my arrays. My code compiles just fine but when it comes to displaying the information I've input into my array it doesn't seem to want to and I'm not sure what I'm doing wrong here. On line 136 originally I had [DVDs [count] = count+1]] but it wouldn't compile. I then put line 136 to [ DVDs[count] = new Inventory();] and I think that's were my issue is but I'm not sure....
// Purpose:the purpose of this software is to display inputs as wells as the stocks and price of inputs.
class Inventory
{
private double ItemNumber; //to store Item number
private String ItemName; //to store Item name
private double UnitsInStock; //to store number of units in stock
private double UnitPrice; //to store Unit price
private double InventoryValue; //to store Inventory value
private double TotalInventory; //to store Total Inventory value

I'm getting ready to code a program that takes record of items loaned and return in a table. I want more than one user to access the program to be able to update the data in the table. For instance, if one user added 5 new items to the table, all other users would be able open the program to see a modified table with 5 new items. Was looking for some advice and was wondering if implementing a database would work best.

I'm (failing at) writing a program that searches an array using binary search, but I can't get it to work.
My code so far is this:
Java Code:
package sorting;
import java.lang.*;
import java.util.*;
public class sorteh {
public static void main(String [] args){
int[] array=new int [20]; //creates new array
for (int x=0;x<array.length;x++){ //populates array
array[x]=x*3+1;
[code]...
I copied what a website did for the sorting part, but if I have low=0 and high=19, wouldn't mid not be an int?

I'm trying to build a method that can search a binary search tree for a specific target and then return the number of probes it took to get there. It seems to me that the best way to do this would be a recursive search method and a counter that tracks the number of calls. But I'm struggling with how to implement this. Here's the code I have so far. what works/doesn't work with the method.
// Method to search the tree for a specific name and
// return the number of probes
public T search(BTNode<T> btNode) {

My program is supposed to be used to keep track of inventory for a company. The user is prompted with a menu that asks them which item they want to update and then gives them another menu that allows them to buy, sell, or change the price of the items. For this, I need to have the variable values to change (based on the input of the user), because they are initially set to specific numbers. How would I do this?
Here's the part of my code that is relevant to this question:
balance = 4000.00;
lampQuantity = 400;
lampPrice = 10;
chairQuantity = 250;
chairPrice = 20.00;
deskQuantity = 300;
deskPrice = 100.00;
System.out.println("Current Balance: $" + balance);
System.out.print("1. Lamps " + lampQuantity);
System.out.println(" at $" + lampPrice);
System.out.print("2. Chairs " + chairQuantity);
System.out.println(" at $" + chairPrice);
[Code] .....
