Calculate Total Price And Display Total In Order Class
Oct 11, 2014I'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?
Java Program That Specifies Three One-dimensional Arrays Names Price / Amount And Total
Dec 2, 2014Recently 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

Baseball Team - Calculate Total Amount Of Home Runs Hit By Batters
Mar 24, 2014So I have a class called Team that is a collection of players and managers for a baseball team, and one of my required methods is to calculate the total amount of Home Runs hit by the batters. Now along with the Team class I have an abstract Employee class, an abstract Player class and a Batter class that extends the Player class I thought this would be fairly easy but it is coming out to be pretty hard my code is as follow:
class Team {
public int _numPitcher;
public int _numBatter;
public String _manager;
public ArrayList<Player> team;
[Code] ....
The total salary works awesome but for some reason when I try and call up how many home runs a player has it wont call correctly I get this red line under my code that says: The method getHomeRuns() is undefined for type Player. I am trying to call this from the batter class which is an extension of the Player class...

How To Get Total Number Of Pennies In Dollar Amount For The Output Of Total Pay
Mar 28, 2014 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?
Client Class - Cannot Get Total Price To Recognize Surcharge
Apr 26, 2015I 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, 2014In 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");

Calculate And Display Price Of Each Object Each Year For 5 Years
Apr 18, 2015For 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.
Create A Program That Calculate Price Of Carpeting For Rectangle Rooms
Apr 23, 2014I 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)

//store sales argument from sales field
public void setSales(double sal)

I know that i have to fix some of the semantics . I have this code that I made earlier, is there an easy way to make it into a GUI interface? Or will I have to go throughthe code lines to add the JOptionPane? And I am a little confused on how to make a list (array) for the commission rate.
Calculations / Conversions - Calculate Correct Amount Of Change Due To A Customer
Sep 12, 2014Here are the instructions to my assignment:
A shopkeeper in Diagon Alley needs you to write a program that will calculate the correct amount of change due to a customer. (In Diagon Alley they use three coins with different values, given below).
1. Prompt the user to input the amount of sale in Galleons, Sickles, and Knuts.
2. Prompt the user to input the amount of money given by the customer in Galleons, Sickles, and Knuts.
3. Create constants that represent:
a. 1 Galleon = 17 Sickles
b. 1 Sickle = 29 Knuts
4. Perform the necessary calculations and conversions to compute the correct change in the least number of coins.
5. create a formatted receipt recording the entire transaction.
Here are what is steps 1 and 2 and 5 but problem with are 3 and 4. I need to create the constants and use proper conversions to give the right amount of change back.
Java Code:
import java.util.Scanner;
public class OperatorFormatting {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Welcome to Flourish and Blotts");
[Code] ....
Basically, on steps 3 and 4 which are creating the constants and using the to make the proper conversions to give the customer the proper amount of change Due.
How To Calculate Total Age In Months And Store As Variable
Feb 9, 2015I 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.

For Loop - Calculate Total Of Series Of Numbers?
Nov 10, 2014So 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--)

Calculate All Total Amounts By Adding All Rows
Jun 12, 2014table.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.
Enter Customer Information And Calculate Total Bill
Feb 28, 2014You 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
