Adding Sort And Total Inventory Methods In Inventory Class
Apr 30, 2014
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
I created a Test main method to test my Inventory and InventoryItem class to see if they are functioning properly. I am currently trying to read a text .dat file, but I keep getting "...cannot find symbol" for descripIn when I try to compile it.
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:
package inventoryprogram4; import java.util.Scanner; public class Inventoryprogram4 { static GUI mainGUI = new GUI(); static String outText = "";
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.For the inventoryTest class, I only need to declare an array of the inventory class by making an instance of the inventory.
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
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; int numberSold;
Why does it keep giving me the error saying that RetailItem[] inventory not found(from the parameter) if its stated above?
RetailItem[] inventory = {jacket, jeans, shirt}; //Display the inventory in the console display(inventory) //Process a series of RetailItem sales processSales(inventory);
//Display the updated inventory of Retailitems display(inventory);
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
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:
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.
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'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 need to write a program that will create an inventory file as a random access file. The problem that I am having is that among the things I need to add to the random access file is a "car name". Since random access files are byte based I don't know how I could possibly write and then read a string value.
I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder; import javax.swing.*; public class UseOrder { /** * @param args the command line arguments */ public static void main(String[] args) { Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?
Alright, so i'm working on this and what I want to do is calculate all of the answers when the values of the correct answer = 1 and the incorrect answer = -1 so at the end of the test I can calculate answer + answer2 + answer3 and so on to get a total score...How do I do this? I've been looking online for 3 hours and i'm just stumped.
import java.util.Scanner; class HorticultureQuiz { public static void main(String[] args){ String name; String major; String confidence;
[Code] ....
I thought I could make each answer = to 1 but then I would need a -1 if the answer was incorrect so I tried this.
char answer = sc.nextLine().toLowerCase().charAt(0); if (answer == 't' || answer == 'T') answer = 1; { System.out.print("Great Job, that is correct!"); } else answer = -1; { System.out.print("Correct answer is false"); }
This is what I've tried so far. What i want to do is to calculate all Total Amounts by adding all the rows (5th column only),as 5th column has total amount for 1 product, and set the text for a JTextField whenever the 5th column of any row changes its value.But this isn't working my way. I have also tried keyListener to trigger that change at Enter key typed but that also don't work for me.
Here is my problem: if I want to add a number of X consecutive values in an array and get the minimal total value along with the indexes that caused this result, how can I do that?
For example:
X = 2 array[4] = (5,2,8,6,7)
start adding every 2 consecutive values as following:
I'm just not noticing why it won't display the answer. I'm trying to solve this book problem......
"Write a for loop that calculates the total of the follower series of numbers:
1/30 + 2/29 + 3/28......+30/1"
Here is what I have..
public static void main(String[] args) { double total = 0; for (double a = 1, b = 30; b < 1; a++, b--) { total += (a / b); } System.out.println(total); } }
When launched, the output is 0.0. I tried changing the variables a and b to doubles but didn't change anything...
Max has a row of N boxes (1 <= N <= 1,000). Each box weighs some value W (1 <= W <= 10,000), which will be unique among all boxes. Max would like to sort his boxes from lightest to heaviest, and must decide between Insertion Sort and Selection Sort to do so. Moving a box any distance D requires (W * D) units of work. Max determine which of the two sorting methods will require the least work.
Both of the sort methods work and counting the work in the sequential sort works fine. For some reason that I can't figure out, I am not counting the insertion sort right.
import java.util.Arrays; public class LeastWork { import java.util.Arrays; public class LeastWork { public int leastWork(int[] boxes) { int low; int temp; int sWork = 0;
I have a project where I must sort a collection of songs by a number of fields: year, rank, title and artist. in the project, we must use certain methods and we cannot add others without getting marked down. Here are the specific requirements:
Sorting
The -sortBy option will cause the output to be sorted by a particular field. If this option is specified, the output should be ordered according to the field named. If there are ties, the tied songs should appear in same order in which they were in the input file. If no -sortBy option is specified, the output should maintain the order of the input file.
public void sortYear()
Order the songs in this collection by year (ascending).public void sortRank() Order the songs in this collection by rank (ascending).public void sortArtist() Order the songs in this collection lexicographically by artist (ascending, case-insensitive).public void sortTitle() Order the songs in this collection lexicographically by title (ascending, case-insensitive).
How do you declare methods for a class within the class whilst objects of the class are declared else where?
Say for instance, I have a main class Wall, and another class called Clock, and because they are both GUI based, I want to put a Clock on the Wall, so I have declared an instance object of Clock in the Wall class (Wall extends JFrame, and Clock extends JPanel).
I now want to have methods such as setClock, resetClock in the Clock class, but im having trouble in being able to refer to the Clock object thats been declared in the Wall class.
Is this possible? Or am I trying to do something thats not possible? Or maybe I've missed something really obvious?
The total cost of your order is: $8.4 ---------------------------------------------------- Notice that the total should be $9.4, rather than $8.4. It is odd because I was able to add a surcharge to my coffee(50 cents), and it does in fact recognize it when calculating the price of the coffee. So why won't my totalPrice in the client class recognize it?
Here is my Client class:
public class CoffeeShop { public static void main(String[] args) //One coffee Coffee coffee = new Coffee(16,"mocha"); coffee.set_price_per_oz(coffee.size);
I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner; import java.text.DecimalFormat; public class PenniesForPay { public static void main(String[] args) { int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?
I am working on a program that simulates a bug moving along a horizontal line, My code works correctly when I test it in it's own class but when I tried testing my constructor and methods in a test class I received an error saying, "package stinkBug does not exist" on lines with my methods. However, stinkbug is not a package.
