Invoice Program - Convert Strings For Quantity And Price To Numeric Types

Feb 12, 2015

In the test program, you will need to convert the Strings for quantity and price to numeric types. To do this, you could use the Integer.parseInt() method and the Double.parseDouble() methods. I'm not sure what he means by that. I attempted it in my program but I get these errors

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
number cannot be resolved to a variable
description cannot be resolved to a variable
quantity cannot be resolved to a variable
price cannot be resolved to a variable
Duplicate local variable quantity
Duplicate local variable price
Syntax error on token "myInvoice", delete this token
The method getinvoiceAmount() is undefined for the type String

at InvoiceTest.main(InvoiceTest.java:7)

Code:
 
public class Invoice
{
private String number; //Instance variables
private String description;//Instance variables
private int quantity;//Instance variables

Sorting Arraylist By Quantity

Apr 22, 2015

I'm getting this error:

The operator < is undefined for the argument type(s) java.util.ArrayList<FacebookUser>, java.util.ArrayList<FacebookUser>

For this:

public int compare(FacebookUser o1, FacebookUser o2)
{
int returnValue = 0;
if (o1.friends < o2.friends)
returnValue = -1;

Same as for the second if condition. How can I fix this exactly? What I'm doing is trying to sort Facebook users by the most to least amount of friends.

Clear Button - How To Fix Price To Stop Adding Up

Apr 26, 2014

I've got my clear button to work on most of the stuff I want, however I cant figure out how to fix the price to stop adding up. e.g. hit a button image with a price of 599.99, hit the clear button to empty, select price of 599.99 again then it display 1199.98.

sofa method

if (source == jBSofa) {
System.out.println("Sofa"); {
dTotal = dTotal + 599.99;
jTotal.setText(Double.toString(dTotal));
jTotal.setText(String.format("%.2f", dTotal));
}

Reset method

private void Reset() {
jTTotal.setText(" ");
jTotal.setText(" "); //sub total clear
jTTotalTotal.setText(" ");

Calculate And Display Price Of Each Object Each Year For 5 Years

Apr 18, 2015

For this program I am calculating the annual costs of 5 office supplies (user input) each with a 5.7% inflation. The user inputs the cost of each object and my program must calculate and display the price of each object each year for 5 years. I already have this part. What I need is how to add the total costs of all 5 supplies per year and display each total cost. Here is the program:

import java.util.Scanner;//Using keyboard to enter data
//Start of Class
public class OfficeSupplyCalculator {
//Start of Method
public static void main(String args[]) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the first item");

[Code] .....

At the moment all I get for the grand total loop is the same number showing up 5 times. I feel like the problem is how I am declaring the grandtotalperyear variable but I'm not sure what is wrong.

Client Class - Cannot Get Total Price To Recognize Surcharge

Apr 26, 2015

I am almost finished with my code. The only hangup I am having is that in my client class, I can't get the total price to recognize a surcharge.

This is my output:
-------------------------------------------------
Your order consists of:

coffee, type mocha, size large, cost: $5.8
tea, flavor earl grey, size medium, cost: $3.6

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);

[Code] ....

Cumulative Sum - Display Total Price From All Loops Added Together

Feb 27, 2014

In the code below, under calculations, I have x=totalPrice+xXxXxX. Obviously the x's were just place holders, but I wanted to know if there was any way to add something there so the program would tally the totalPrice, store it in the x variable outside the loop, so when the loop ended it would display the total price from all the loops added together where I have System.out.println("TOTAL OF ALL ORDERS: $"+ round.format(x)); at the very end.

Java Code:

import java.util.Scanner;
import java.text.DecimalFormat;
public class ModifyOrderV2TEST
{
public static void main(String [] args)
{
//Rounding
DecimalFormat round = new DecimalFormat("0.00");

Keeping Track Of Product With Highest Price - Loop Condition

Sep 22, 2014

The Program prompts the user to enter the number of products in the product catalog. The program should then prompt the user for the name and the price of each product in the product catalog. Once all of the products have been entered, the program should output the product information (name and price) of the most expensive product in the catalog. Your solution to keep track of the product with the highest price.

import java.util.Scanner;
public class ProductTester {
private static final String price = null;
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
System.out.print("Enter the number of Products: ");
int count = console.nextInt();

Create A Program That Calculate Price Of Carpeting For Rectangle Rooms

Apr 23, 2014

I am not getting any syntax errors but the program simply does nothing when I run it.

I literally just get "run: BUILD SUCCESSFUL (total time: 3 seconds)".

So basically, I need to create a program that calculates the price of carpeting for rectangle rooms.(multiply the area of the floor by the price per square foot of the carpet).

-The RoomDimension class should have two fields: one for length and one for width, and a method that returns the area of the room
-The RoomCarpet class that has a RoomDimension object as a field, a field for the cost of carpet per square foot, and a method that returns the total cost of the carpet

Here is what I have:

package roomdimension.java;
public class RoomDimension {

private double length=0;
private double width=0;
private final double area = length * width;

public void RoomDimension(double len, double w)

[Code] ....

Java Program That Specifies Three One-dimensional Arrays Names Price / Amount And Total

Dec 2, 2014

Recently I have missed a few weeks of my class due to family emergencies. Because of this I have missed very important lectures. My professor has assigned me the following assignment:

Prices Write a Java program that specifies three one-dimensional arrays names price, amount, and total. Each array should be capable of holding 10 elements. Using a loop, input values for the price and amount arrays. The entries in the total array should be the product of the corresponding values in the price and amount arrays. After all the data have been entered, display the following output:

Total Price Amount

==== ==== ======

Under each column heading display the appropriate value.

I know how to display everything using printf, how to create the actual arrays and define the array size, but I am confused on how and what loop to use and how to construct it. This is what I have managed to write up so far:

import java.util.Scanner; // Imports the Scanner class
import java.text.DecimalFormat; // Imports the DecimalFormat class

public class Prices
{
public static void main(String [] args)
{
double[] price = new double[10];
double[] amount = new double[10];
double[] total = new double[10];

// Create a new Scanner object
Scanner keyboard = new Scanner(System.in);
} //End of main method
} // End of public class

How To Make Print Employee Button To Print Info Of Other Class

Apr 12, 2014

Basically the class is supposed to have a static variable that keeps track of the number of companies (numberOfCompanies) that have been created and a static method that returns the value of this variable. I need to have a constructor and a method to addEmployee, a method to printCompany, and a toString method. The addEmployee method will check that there is only 1 salesperson, 2 designers, and 4 manufacturing persons at a time and will check that there are no more than 7 employees of the company.

The addEmployee method will return a String indicating what the error is (i.e. "There is already a sales person in this company") or a null if the employee was added. If attempting to name a third company, an error message will be shown. what i have so far but my print company mmethod returns null company class :in which i am obliged to use inputdialog because it says that it cannot return void when i use the showmeassage diaolog.

company class:

import java.util.ArrayList;
import javax.swing.JOptionPane;
public class Company {
private ArrayList<Employees> list ;
private static int numberOfCompanies;

[Code] ....

error message when print button is clicked:

Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: JOptionPane: parentComponent does not have a valid parent

Calculate Total Price And Display Total In Order Class

Oct 11, 2014

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?
