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.
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 does the program know to calculate for only one year?
public class Interest2 { public static void main(String[] args) { double principal; // The value of the investment. double rate; // The annual interest rate. double interest; // The interest earned during the year.
I am making a shopping cart web, but some problems I meet about how to calculate the total price
I use ajax in product list web and if I choose one product , it will send the Id that I read from MySql to servlet and use session to save it . and I click the button jump to the cart, the page cart.jsp will read information from session ,and find product information from mysql by id , now my question is where I calculate the total price, servlet or jsp?
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 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;
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
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");
The pay rate is php 35.00 per hour. any hours worked after 40 hours is paid at rate of 2 times the normal hourly rate. Calculate and display the Normal Pay, The overtime pay, and the total pay.
OUTPUT MUST BE:
Sample 1 :
Enter Hours Worked: 40 (Sample) Normal Pay: 1400 (Sample) Overtime Pay: 0 (Sample) Total Pay: 1400 (Sample)
Sample 2 :
Enter Hours Worked: 41 (Sample) Normal Pay: 1400 (Sample) Overtime Pay: 70 (Sample) Total Pay: 1470 (Sample)
Here is my code or something, but i cant finish it.
import java.util.Scanner; public class Workpay { public static void main(String[]args) { Scanner in = new Scanner (System.in); int hours; int normalpay = 35;
I have to write a program that calculates and displays a person's body mass index (BMI). The BMI is often used to determine whether a person with sedentary lifestyle is overweight or underweight for his or her height. A person's BMI is calaculated with the following formula:
BMI = Weight X 703/Height^2
where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person's weight is considered optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered underweight. If the BMI value is greater than 25, the person is considered overweight.However I can't seem to get rid of these errors:
----jGRASP exec: javac BMI.java BMI.java:28: error: cannot find symbol Scanner keyboard = new Scanner(System.in); ^ symbol: class Scanner location: class BMI BMI.java:28: error: cannot find symbol
I am still new to Java and have an assignment that I am stuck on. I believe I got the boolean function correct, however I cannot figure out what to write in the main function. I have exhausted searching, and trying different loops, arrays, etc.
Alright, so I'm having problems with lines 11 - 55. I'm trying to calculate the possible tiles the clicked unit can be moved on and display it to the player.
The field is a 9 (columns) by 5 (rows) grid. A unit with can move tiles horizontally or vertically based on its movement.
Example: (unit = o; possible tiles = x) (assuming movement of 2).
I tried to calculate movement by finding out what column the unit is in, subtracting the column it wants to go to, multiplying the difference by *-1 if the difference is less than 0. Then, doing the same with rows and adding the difference of columns to the difference of rows and comparing it to the unit's movement. Unfortunately, with my code, it seems to move in any directions.
@Override public void mouseClicked(MouseEvent e) { if (Main.cards.size() > 0) { mainloop: for (int i = 0; i < Main.cards.size(); i++) { Card c = (Card) Main.cards.get(i); int startingColumn = 0;
Write a program that will calculate the cost of a ticket order and display the receipt for the customer on the screen. There are 2 ticket prices: adult, and senior citizen. Adult seats are $4.50 and senior citizen seats are $3.50. If more than 5 senior citizen tickets are purchased, the customer gets an extra 20% off the of the ticket order. If more than 10 regular seats are purchased, the customer gets an additional 10% off the cost of the order. A customer can only place an order for one type of ticket. Output the type of ticket purchased, the number of tickets purchased, the gross cost, the amount of the discount, and the final cost of the order.
I am having errors with incaompatible varriables comparing float with doubles.
public class lab3 { static Library myLib; public static void main (String [] args) { Library myLib = new Library(); //Instance the Library class int ticketNum; //Number of Tickets
I'm trying to create a GUI application that calculates and displays the total cost for certain automotive maintenance services. The application should contain hree classes: 1) the main class that creates and displays the window; 2) a panel for the routine services and 3) a panel for the non-routine services. 2 and 3 are instantiated in 1. I'm pretty positive the error lies in the NonRoutinePanel class because when I comment it out of the main class the program runs fine. But I can't quite figure out which lines of code or methods are causing the problem.
When I try running the program I get these error messages:
Exception in thread "main" java.lang.NullPointerException at java.awt.Container.addImpl(Container.java:1040) at java.awt.Container.add(Container.java:958) at javax.swing.JFrame.addImpl(JFrame.java:540) at java.awt.Container.add(Container.java:926) at JoesAutomotiveGUI.<init>(JoesAutomotiveGUI.java:38) at JoesAutomotiveGUI.main(JoesAutomotiveGUI.java:111)
Here's my code for the three classes:
import javax.swing.*; // Needed for Swing class import java.awt.*; // Needed for BorderLayout class public class RoutineMaintenancePanel extends JPanel { public final double oilChange = 26.00;// cost of oil change public final double lubeJob = 18.00;// cost of lube job
Here's the small project... but how can I return the value (amount) in 10 years ? The way I did, the program just doesnt return anything...
import java.util.Scanner; public class FutureValue { public static void main (String []args) { double amount = 0; double apr = 0; System.out.println("How much money would you like to invest?");
I am trying to get an object to display twice from a class in an applet.
Java Code:
if (label == 4) { game.stop(); timer.start(); result.setText(" You Have Destroyed the World"); marFoundDisplay.setText("Martian: " + String.valueOf(mCount)); jupFoundDisplay.setText("Jupiterian: " + String.valueOf(jCount)); highScoreDisplay.setText("HighScore : " + String.valueOf(HighScore)); j.draw(g, 350, 150); j.draw(g, 350, 150); mh_sh_highlight_all('java');
Obviously calling it twice doesn't get the desired effect, I'm ultimately trying to get them to be side by side in the middle of the applet, but clearly what I've done won't achieve that.Can you provide me an example that would allow me to display the code below to have the item be displayed twice side by side?
so I had to make a program that prompts the user to enter a loan amount and the years for the loan and I have the conversions and everything my only issue is that when the chart pops up it just looks like a bunch of numbers and its missing the column headers
for example
Interest Rate Monthly Payment Total Payment
import java.util.Scanner; public class InterestRate { public static void main(String[] args) { double monthlypayment = 0; double totalpayment = 0; Scanner input = new Scanner(System.in); System.out.println("Enter Loan Amount");
import java.util.Scanner; public class days { public EnumTest () { this.day = weeks/months/years} final int daysInMonth = 30; //constants final int monthsInYear = 12; final int daysInWeek = 7; public void convert()
[Code] ....
after compiling it shows invalid method declaration ; return type required.
