Electricity Bill Project - How To Incorporate Rate Per Month And Three Rate Zones
Jan 30, 2014
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.

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 quiet stuck on this one.

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.

Here is what im trying to do
Write a class that accepts a user's hourly rate of pay and the number of hours worked. Display the user's gross pay (gross pay = hours worked * hourly rate), the tax withheld (tax withheld = gross pay * tax rate) and the net pay (net pay = gross pay - tax withheld).Use a named constant for storing the tax rate of 0.15
Here is my Code:
import java.util.Scanner;
class Tutorial

I've been working on a question using parallel arrays where the user inputs an integer 1-12 and the output will be the name of the month and the number of days in that month. This is what I have so far
import java.util.*;
public class DaysMonth
{
public static void main (String args[]) {
Scanner keyIn = new Scanner(System.in);
int[] days = new int[]{31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
[Code] ....
After I enter the user int it just ends.

I want to be able to use the current date to solve a math problem, specifically as follows:If today is March 17, the math problem of the day should be:
(Month times Day of Month) + 99 = Answer of the Day
(3 x 17) + 99 = 150
How can I create a java script to find the current month and the current day of month, multiple those two together, then add 99 and display the answer as a result.

If you store a Timestamp in a database (in my case, I'm looking at DB2), doesn't something on the back end convert it to UTC? And then when you read it back out, it gets converted to the local time zone? How does this happen?
Lets say you are using a computer in one time zone, but the database is running on a server in another time zone. What conversions take place upon storage and then retrieval?
And here is where it gets a little more Java specific. Using a PreparedStatement or a ResultSet, you can change the time zone when setting and retrieving a Timestamp.
Example:
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
ps.setTimestamp(2, timestamp, calendar);
And you can read it out from a ResultSet in a similar fashion.
However, isn't using such methods technically wrong? If the database is trying to store your instant in time accurately, doesn't specifying a Calendar other than the one in your local time zone cause the database to actually store an incorrect instant in time?
So I need to read Timestamps from a database, and I've been told they are stored as GMT. This has caused me great confusion. I think what I need to do is just read it out from the result set using a Calendar set for GMT timezone.

I am trying to do this program. it compiles and everything but the numbers are not coming out right. Heres the problem.
Write a program that computes the tax and tip on a restaurant bill. The program should use JOptionPane to ask the user to enter the charge for the meal. The tax should be 6.75 percent of the meal charge. The tip should be 15 percent of the total after adding the tax. Display the meal charge, tax amount, tip amount, and total bill on the screen.

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

What to do with this JAVA code?
This is the code that I need to do without using the Joptionpane:
An Internet service provider has three different subscription packages for its customers:
Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per month unlimited access is provided.
Write a program that calculates a customer's monthly bill. It should ask the user to enter the letter of the package the customer has purchased (A, B, or C) and the number of hours that were used. It should then display the total charges.
This is what I have so far : Cannot use Joptionpaneshowinputdialog
/* A demonstration of how to use Decision Structures
import java.util.Scanner;
/**
This program demonstrates a switch statement.
*/
public static void main(String[] args)
{
char packageLetter;
int hoursUsed;

Im working on an assignment with the following instructions:
Create a Date class with the following capabilities:
a)Output the date in multiple formats such as
MM/DD/YYYY
June 14, 1992
b )Use overloaded constructors to create Date objects initialized with dates of the formats in part a).
You should only have 3 member data: integer month, integer day, and integer year. Also, you should have at least 2 constructors and 2 methods in your Date.java.

I'm working on a program that prompts the user to enter the year and first day of the year and displays the calendar table for that year on the console. For example, if the user entered the year 2005, and 6 for Saturday, Juanuary,1, 2005, the program should then display the calendar for each month of the year.
I have written the program and solved the problem for the most part. Only, I'm having terrific difficulty getting the output to properly format. I'm *almost* there. I'll post my program below and then output.
import java.util.Scanner;
public class DisplayCalendar {

Scanner scanner = new Scanner(System.in);
System.out.print("Enter the year: ");
int year = scanner.nextInt();
