Calculate Total Price At The End Of Order - Decimal Format
Apr 13, 2015
I have an assignment to create a JFrame pizzaorder and at the end of this order after the totalprice is calculated I need to format the number to ##.## but I keep getting a cannot find symbol error.
Source Code:
import java.awt.*;
import javax.swing.*;
import javax.swing.event.*;
import java.awt.event.*;
public class pizzaorder extends JFrame implements ItemListener, ListSelectionListener
//top section will have centered title telling the name, and under it seperate instructions to choose your pizza and toppings

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?

How can I do the work below in Java
In this main class, create 5 objects of the class Menu, as defined in the table below.
Name amount of calories cooking time price per person number of drinks
Fufu and Groundnut Soup 564.65 2515.572
Red Red 345 12 9.980
Rice and Beef Stew 560.4 1512.651
Ga Kenkey and Fish 780 10 10.15 1
Banku and Tilapia 450.4 35 25.17 2
Exercise d
In your main class create an array of length 5, and store the 5 objects (Exercise c) into the array. You can use any name for your array.
From the array, use a loop to: Print the details of all the objects using the method you defined in Exercise b.
Exercise e
Use another loop to:
-Print only the name and cooking time of all the dishes that take less than 30 minutes to cook. Hint: you may use the getter methods for the name and cooking time attributes, and then, print these values (name, cooking time).
Exercise f
Use another loop to :
-Calculate and print the total price of all the objects (in the array).
-Calculate the total price of all the objects with VAT included for each dish (VAT rate is 17.5%).
Submission
-Create a folder with your index number as its name.
-Copy your Java Project folder into the created folder.
-Print a hard copy of your classes.
-Submit both soft copy and hard copy of your project

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] ....

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");

Why is my program not calculating the total and average of the price of the items and not printing it out?
Java Code:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package assignment4;
[code]...
It prints out everything but the total of the items and I dont know why. :(

How would I program a counter that will return the total number of search, failed searches and correct searches. The second thing is how can a return the price of the search methods with out calling for it specifically. Here is my current code.
package stu.paston.program7;
import java.util.Scanner;
public class MainClass

public static void main(String[] args)
{
InventoryClass productData= new InventoryClass();

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

double price;
String PriceStr;
int quantity;
String QuantityStr;
PriceStr = JOptionPane.showInputDialog("Enter the price: ");
price = Double.parseDouble(PriceStr);
QuantityStr = JOptionPane.showInputDialog("Enter the quantity: ");
[code]....
So i tried to make it allows the user can continue pick the option and calculate the total of every time they select the option, mine is only 2 times.

The code is below and the problem I am having is the numbers after the decimal won't add together for the total I am teaching myself java through liang's 10th edition book and I took one of the sample programs further than what was shown. The one in the book only shows the tax amount I simply wanted to make it so that the purchase amount and the tax amount would add together
package javalearning;
import java.util.Scanner;
public class FindingTax {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.print("Enter Purchase amount: ");

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.

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)

I am using NetBeans IDE 8.0.2 to program Java code. I am a beginner in Java.
Instead of getting two decimal places after the point, I am getting three despite using the code format for two ("##.##"). Actually, this happens even if I remove the format code between the quotes. It is as if the program cannot see the format code. Why this happens ?
Here is the relevant program code:
private void convertButtonActionPerformed(java.awt.event.Action Event evt) {
double inputNumber = 0;
// sets the decimal format

I am working on a program where i calculate a fee using a method. I know i have to import the decimal format utility of java. "import java.text.DecimalFormat;" then i have to create an object for the decimal format. With "DecimalFormat f = new DecimalFormat("0.00");" What i am wondering how do i apply it to my system.out.println statement. I know i have to use for instance f.format(calculateFee()); Is that the right syntax for displaying the results because i generate a syntax error that way.

I am working on a project that just calculates simple interest based upon a principal and a percent interest rate written as .xxxx from user.
I need the Loan amount and the final interest calculation to show up as a currency with commas in appropriate areas, the Rate to be expressed as X.xxx% instead of .xxxx
I keep getting this error when I compile:
C:JavaInterestCalculator.java:46: error: incompatible types: String cannot be converted to double
principal = formatter.format(principal);
^
C:JavaInterestCalculator.java:49: error: incompatible types: String cannot be converted to double
rate = formatter.format(rate);

C:JavaInterestCalculator.java:52: error: incompatible types: String cannot be converted to double
totalInterest = formatter.format(totalInterest);

3 errors
Tool completed with exit code 1
And here is my code
import java.util.Scanner;
import java.text.NumberFormat;

I am working with a program I wrote for class. I got it to compile and do what I want, But I was wondering how I can format my methods to to display a decimal with 1-2 decimal places. Would I create a method in my NumberAnalysis class to do it for me? Or would I declare an instance of the DecimalFormat class in my main method?
import java.util.Scanner; //Needed for Scanner Class
import java.io.*; //Need for File and IOException
import java.text.DecimalFormat;
public class Ex8_11 {
public static void main(String[] args) throws IOException{
{
DecimalFormat decformatter = new DecimalFormat("#0.00");
[Code] .....
This is my output:
Lowest Number: 1.09
Highest Number: 82.76
Total Number: 367.89000000000004
Total Average Number: 30.657500000000002
Think I just solved the answer to my own question, I did it by declaring double variables in my main method and called the methods and instantiated the variables into the methods... Is there a better way to do this?
package lesson4.skowronek;
import java.util.Scanner; //Needed for Scanner Class
import java.io.*; //Need for File and IOException
import java.text.DecimalFormat;
public class Ex8_11 {

I was wondering how can I calculate total age in months and store it as variable? this is what I have so far:
*
* You will ask the user to provide their name (as a single word, assume first name here)
* You will ask the user their age in full years (no fraction or months)
* You will ask the user how many full months since their last birthday (again, whole numbers here).
*
* You will use this information to calculate the user's age in months and use that information to print out a greeting.

So basically, I've been trying to create a for loop that asks the user for a number between 1 and 30, then calculates the total of the series of numbers. For example, if 15 is entered, the calculation should be 1/15+2/14+3/13+...15/1 which would equal approximately 38.1. The problem I'm having is that the code doesn't loop whenever I type a number for some reason, which results in a very incorrect calculation. Here is my code so far:
import java.util.Scanner;
public class HmwLoop {
public static void main(String[] args) {
double sum = 0;
for (double num1 = 1, num2 = 30; num1 <= 30 && num2 >= 1; num1++, num2--)

table.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent e) {
System.out.println("Value changed");
if(Float.parseFloat(table.getModel().getValueAt(table.getSelectedRow(), 4).toString()) != 0.0){
System.out.println(getTotal());
totalAmount.setText(""+getTotal());
}
}
});
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.

You have a store that sells the following items:
Shoes $50.00
T-shirts $30.00
Shorts $75.00
Caps $15.00
Jackets $100.00
Your sales associates need a program where they can enter customer information and calculate the customer's total bill. When the sales associate enters the program they should be presented with this main menu.
Enter customer information
Display Total Bill
Quit
If the sales associate selects option 1, the program should allow the sales associate to input their name, address, and e-mail address. Your program should then display this customer information to the screen with a message that the customer has been added to the customer list.
If the sales associate selects option 2, the program should ask the sales associate for the customer's name, product that the customer is purchasing, the quantity, and the price of the product. The total bill will then be displayed to the screen and should include the following:
- The customer's name.
- The product the customer is purchasing, the quantity, and total cost
- The amount of tax 8%
- The total cost with tax.
Example Total Bill Output:
John Doe
Product Purchased Quantity Total Cost
Shoes 2 $100.00
Tax 8%: $8.00
Total Cost: $108.00
HOW DO I WIITE IT
