Inventory Program - Displaying Information (Input From Array)
Sep 13, 2014
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 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;
I am new to Java an have to Create a program that keeps track of the following information input by the user: First Name, Last Name, Phone Number, and Age. Now - let's store this in a multidimensional array that will hold 10 of these contacts. So our multidimensional array will need to be 10 rows and 4 columns.You should be able to add and remove contacts in the array.
I have been creating a Java program to track inventory using an array. I need to add a search function to it to take a term, input through a text field, and locate a matching instance within the array. How can I code a JButton to grab test input from a JTextField and search for it within the array then display the corresponding information? I also need to add buttons to add and delete items as well.
The main method will drive your program by doing the following:
-Create an array to hold all the individual golfers and par scores (type is Golfer[ ]). -Prompt the user for a data file containing the Par scores and the player names and score. The format of the input file should look like
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 am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
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 = "";
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 let a user input name, age, email, and cell phone number, and commit the input to a text file. They need to add multiple entries. I figured out how to create the file and write to it, but when the user enters a second set of information, the first is overwritten. How can I make the file be added to instead of overwritten? The following is my code:
try { FileWriter writer = new FileWriter("ContactInformation.txt"); BufferedWriter bw = new BufferedWriter(writer); nameTextField.write(bw); bw.newLine();
I am new to using arrays. I need to collect user input for book title, author, and # of pages... store that in an array... and then I'm going to need to be able to sort that array. The dialog boxes come up prompting the user for 5 sets of title, author, and # of pages, but when I try to display that information, it isn't working. I am assuming this means that it's not storing the information correctly... so I want to get this corrected before I even try to sort??
import javax.swing.*; import java.util.*; class LibraryBookSort { public static void main(String[] args) { LibraryBook[] someBooks = new LibraryBook[5];
I'm trying to get data from a GUI input window into an ArrayList and back out via a JTable. I can get the array lists to print to the console within the input class, but I need to wire it to a data container and out through a different class. Here is code from one input class, and its corresponding output class:
Input: public class AddClassroom extends JFrame implements java.awt.event.ActionListener { // UI components // are declared here...
I can insert data in database, delete aslo using JSP. But facing problem while updating the information saved in database as m using MySQL 2008. I want to see the bring saved in database with particular username into the updateinfo.jsp form.
I had to make a program that allowed the user to enter the number of students and the students names and grades and then print out the name with the grade in descending order. right now I only have it where it prints the names out in descending order. how do I get it the print out with the grade?
Here is my code
import java.util.*; public class Grades { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter the number of students: "); int numofstudents = input.nextInt();
This program contains a superclass and a subclass that will gather the following information from the user:
name, address, phone number, and customer number.
Everything works fine except that I have to create a boolean method in this program that is required to determine based on user input whether they want to be added to a mailing list.
I cannot get this method to work with main, each time it is called it will always return the value but main will constantly read the last statement (else, where it will read "not wanting to be added to the mailing list).
The only way I can get this part of the program to work is by adding an equals method in main that ignores the case, but I am required to write a boolean method so this is not allowed.
Superclass:
public class Person { private String name; private String address; private String phoneNum; public Person(String pName, String add, String number) { name = pName; address = add;
i have a program that is to store DVD information and when i enter all the information asked it returns no info. I have a DVD inventory file and a DVD extended file.
DVDinventoryprogram class package inventory2; import java.util.Scanner;
I am trying to find the GCD, add, and remove the biggest and smallest fraction, however I am having trouble getting user input into the array and getting the information out of it (Variable f).
Scanner keyb = new Scanner(System.in); Fraction[] frak = new Fraction[7];
Main_Class try { for (Fraction f : frak){ // for each array in frak print f; System.out.println("Enter Numerator"); int num = keyb.nextInt(); System.out.println("Enter Denominator"); int den = keyb.nextInt(); f = new Fraction(num, den);
I'm trying to take the information from one 2d char array and put it into another char array but instead of traversing the array left to right I want the new array to be top to bottom.
Example fg would be fh hi gi
I'm having trouble getting the information from one to the other.
[code]public static char[][] translateIt(char[][] english){ int rows = english.length; int columns = english[0].length; char[][] chinese = new char[columns][rows]; for(int j=0; j < columns; j++){ for (int i = 0; i < rows; i++){ //chinese[i][j] = english; this is commented out because it didn't work. }//Ending bracket of columns for loop }//Ending bracket of rows for loop
return chinese; }//Ending bracket of translateIt[code]
import java.util.*; public class TrafficIncidents { public static void main(String[] args) { Scanner s = new Scanner (System.in); // Array for days String [][] days = {{"Sat"},
[Code] ....
This is my output:
Day AM PM -------------------------------- Sat Sun Mon Tues Wed Thurs Fri 5 1 1 2 4 1 0
Basically I want to align the AM traffic incidents under the heading "AM" but am not sure how to accomplish this. I am using separate arrays for all three of these types of information and need the info to line up with their respective titles.
I'm having trouble conceptualizing something. I will post the code, it's works exactly as it should. I create an array and Hash Map to display periodic table of elements information after allowing the user to search by element name or symbol. I want the user to also be able to add elements to the periodic table. I can't really conceptualize how I am going to do that with an array I've already created.
Here's code:
//Create element objects. //Here is where I create my "elements" array, and where I could like to prompt the user to add elements, if desicred. Element[] elements = {new Element("Hydrogen", 1, "H", 1.008,1,1), new Element("Lithium",3, "Li", 6.94,2,1)}; // //Maybe it seems if I prompt the user here to add new element names, symbols, weights, etc, I would be overwriting
I'm making a program that displays information for "employee" objects of different types. This works with a hierarchy that goes Person→ Employee→ Fulltime/Adjunct, and a driver that tests the inheritance. The Person class is given and only supplies the name, the employee class manages the year hired and the ID, and the types of employee classes manage the salaries.
One object (called staff[2]) is supposed to first be printed with default information and then later updated via set methods. I figured out how to update the name, but I don't know how to update the rest of the information because the employee's name is managed in the Person class and the reset of the information is managed in the less-general classes, and the objects are all in an array of Person.
How do I call the set methods necessary to update more of staff[2]?Output (scroll to see the updating section)
The current year is 2012
Name: Flintstone, Fred ID Num: BR-1 Year Hired: 2005 Years Of Service: 7 Salary: 65000.12 Fulltime Type Employee
What is printed is much larger than what I've copy and pasted but I can't post it all here.
The error I get is:
Exception in thread "main" java.io.IOException: Stream closed at java.io.BufferedReader.ensureOpen(Unknown Source) at java.io.BufferedReader.readLine(Unknown Source) at java.io.BufferedReader.readLine(Unknown Source) at Map.importMap(Map.java:26) at Map.main(Map.java:44)
