For some reason, the averages aren't calculating correctly. I'm aware I need to convert to double if I'm dividing by an odd amount but that itself isn't the issue. It's just simple easy divisible numbers that are not being calculated correctly. For instance, (10 + 10 + 10 + 50) / 4 = should be 2 but I get 10.
Here is the code:
import java.util.Scanner; public class Avg { public static void main(String[] args){ Scanner inputGains = new Scanner(System.in); int userInput = inputGains.nextInt();
I am not sure how to incorporate the rate per month and the three rate zones.
Problem: Electricity billing charges vary with the season and amount used.
Southwest Power and Light provides electricity at the basic rate of $ 0.10 per kilowatt for the months December through February, 0.12 per kilowatt for the months of March through May, and 0.15 per kilowatt for the remaining months.
Customer billing is divided into three rate zones: 0-350 kilowatts, 351 – 500 kilowatts, and above 500 kilowatts. Usage up to 350 kilowatts is billed at the basic rate. Usage between 350 and 500 kilowatts is billed at 10% above the basic rate. Above 500, billing is 25% above the basic rate. These surcharges apply only to the usage falling within the respective rate zone.

Design a program that will read a file of sales records and produce a sales report. Each record in the file contains a customer's ID, name, a sales amount, and a validated GST code. The GST code is to be applied to the sales amount to determine the sales tax due for that sale, as shown below.
GST CodeGST Rate 0 1 20% 5% 10%
The report is to print a heading "SALES REPORT", and detail lines listing the customer's ID, name, sales amount, sales tax, and total amount due including sales tax.

How would I get my program to display a * for every 100 dollars in sales that the user enters in so: for example the user enters in store 1: $ 400 in sales for the store I want it to display store 1:****
The first part of my code allows the user to enter in whatever values the stores have in sales. The Second half of the code starts at line 19 is my best guess on what I need to do I just am not sure how to get it to display what I need it to.
With fields that holds a tax payer social security number, last name, first name, street address, city zip code, annual income, marital status and tax liability, include a constructor that requires argument that provide values for all other fields other than the tax liability. the constructor calculates the tax liability based on annual income and percentage in the ff table

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.
prompts user for the grades of each of the students and saves them an int array called grades. Your program shall check that the grade is between 0 and 100. program should then check if the grade is equal to or greater than 50, where 50 is the pass rate.
A sample output :
Enter the number of students: 3 Enter the grade for student 1: 55 Enter the grade for student 2: 108
Invalid grade, try again...
Enter the grade for student 2: 56 Enter the grade for student 3: 57
The average is 56.0 The maximum is 57 The minimum grade is 55 The number of fails is 0 The number of passes is 3 ..
I am attempting to make a heart rate calculator program. Here is a little overview of what I am trying to do. It must use a constructor and get and set methods. It must print heart rate ranges and the user's information(age).

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%).

my project is to design a class that stores the number of units sold and has a method that returns the total cost of the purchase..the given info is unit are $99. discounts are 20% for 10-19 units; 30% for 20-49 units; 40% for 50-99 units; and 50% for 100 or more units purchased... When i run the code and put in the units sold it returns: 0 units sold, $0.00 cost, 0% discount. How do I get the output to actually do the equation and give proper information. We were given a demo file from the instructor and had to create a class that works with it first set of code is the demo file:
package chapter4; import java.text.DecimalFormat; import java.util.Scanner; /** * SoftwareSalesDemo Program */ public class SoftwareSalesDemo { public static void main(String[] args) { int units; // To hold units sold
I have this small program that creates a sales opportunity and its related products, and then prints out the opportunity name, total quantity and total price
class Opportunity{ String name; int Amount; String Stage; int Product_quantity;
[Code] .....
The code works as expected, and is successfully prints :
That said, I feel the way the OpportunityCreator class sums up the quantities and prices (see the comments on the code) is very inefficient, and would only work if there were 3 or less products. How can I design this so that it sums the quantities and prices of all the Product objects that I create, regardless of how many of them are? I understand probably I'd need to redesign the whole thing but I'd like to get at least an idea of how this can be achieved.
Originally I was thinking of creating an ArrayList and adding all the prices/quantities there but wasn't sure how to do. I also thought of using a loop to loop through the different object references and sum the quantity/price but was also unsure on how to do so?
I am working on trying to show the average daily sales for the store. I cannot quite figure out why my calculation is not working. Everything works except my average sales is always $0.00... lines 185-189 is where my calculation is located.

The manager of a football stadium wants you to write a program that calculates the total ticket sales after each game. There are four types of tickets: box, sideline, premium, and general admission. After each game, the data is stored in a file in the following format:
ticketPrice numberOfTicketsSold
Sample data might look like:
250 5750
100 28000
50 35750
25 18750
The first line indicates that the box ticket price is $250 and that 5750 tickets were sold at that price.
Your program should input in this data (using Scanner or an input dialog box), then output that data to a message dialog box along with total ticket sales information. Output the total number of tickets sold and the total sale amount. Make your output user-friendly and "pretty". Format your output with two decimal places. Use JOptionPane and the formatting techniques learned in chapter 3 for your output. Example output might be:
5750 Box Tickets sold at $250.00 28000 Sideline Tickets sold at $100.00 35750 Premium Tickets sold at $50.00 18750 General Admission tickets sold at $25.00
gather sales amount for the week display the total of sales display the average of sale display the highest sale amount display the lowest sale amount
using occurrences determine how many times the amount occurred for the week
make a sales main make a sales data
This is what i have so far but I'm confused on how to start the occurrence and where it would be placed in order to get the information from the array
public class SalesData { private double[] sales; // The sales data /** The constructor copies the elements in an array to the sales array. @param s The array to copy. */ public SalesData(double[] s) {
I'm writing this super simple code as I follow along in this java textbook, and I don't know why it's giving me an error in my tester program!
CashRegister.java
public class CashRegister //a cash register totals up sales and computes change due { private double purchase; private double payment; /**establishes instance variables "purchase" and "payment" and assigns them as doubles to store the two amounts later on. the assignment as private makes it so ONLY methods in this class can access these instance variables*/
This specific assignment requires me to write a program that calculates the total sales after each football game. There are 4 types of tickets: box, sideline, premium, and general admission. After each game, data is stored in a file... then output the number of tickets sold and total sale amount. Format your output with 2 decimal places.
Okay I know there is a I/O section and wasnt sure where to post this. I need some insight on how to use file input and output as well ... Here is my program:
