Write a program to calculate the telephone charges for four customers. The data for each customer consists of NAME, PREVIOUS METER READING, PRESENT METER READING. The difference between the two readings gives the number of units used by the customer for the period under consideration.
The amount due for each customer is calculated by: UNITS USED * RATE PER UNIT + RENTAL CHARGE The rate per unit and rental charge is assumed to be the same for all customers and must be input once only.
Your program must:
a. Input the rate and rental charge
b. Read the data for each customer and calculate the amount due
c. Print the information under suitable headings
d. Calculate and print the total amount due to the telephone company

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.
import javax.swing.JOptionPane;
public class Bill {

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

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.

I'm trying to print out the results of a program that calculates the number of seats the parties will get in an election.I have to print the partial results and the national results.
I can print te number of seats per party in each constituency, but how can i sum all seats per party in each constituency and print the national results?I'm working with vectors, which I know it might not be the best option, but everything is working, except the fact that I can't loop throuhg the vector and retrieve the total sum per party.Like, adding the seats for labour party in Constituency A and B and C, etc, and print the sum. And do the same for conservative party.Is it possible, or doIhave to create a method in Parties class to solve the problem?
This is what I have now.
for (Parties p : h.geral) {
show += String.format("Constituency - %5s - %5s - %d%n",
p.getConstituency(), p.getParty(), p.getNum_seats());
}
Develop an algorithm for a Java program that takes as input a single letter and displays the corresponding digit on the telephone. The letters and digits on a telephone are grouped this way:
2 = ABC 3 = DEF 4 = GHI 5 = JK 6 = MNO 7 = PQRS 8 = TUV 9 = WXYZ
The screen dialog might look like this: Enter a single letter, and I will tell you what the corresponding digit is on the telephone. R The digit 7 corresponds to the letter R on the telephone.
The program should display a message indicating that there is no matching digit for any non-alphabetic character entered by the user. Also, the application should recognize only uppercase letters. If a user enters a lowercase letter, the program should display an error message. Prompt the user with an informative message for the input value as shown above.
The application should include the input letter as part of the output.
Write the algorithm to solve this problem including steps for prompting the user, getting input from the keyboard, and displaying the results.
Write the Java program that you designed, using your algorithm as a guide. Use your algorithm as comments in the body of the main method.
Use proper indentation, and meaningful identifiers throughout the code.
Assume the tanker is a cylinder of length 19.35 feet and volume 1320 gallons. What is the diameter in feet of the tanker truck? To solve this problem, write a Java program to calculate the diameter. For full credit, your Java application must follow these specifications.
1. The program must interactively input the capacity of the tanker in gallons and its length in feet. This should be done in the main method of your Tester class.
2. The input data should then be used to construct a TankerTruck object. You will need to write the TankerTruck class.
3. A TankerTruck method should be used by main to calculate the resulting diameter of the truck in feet.
4. Your program should use the standard Java constant for the math constant PI.
5. The output should be displayed using fixed-point notation, rounding to one decimal place of precision
Write method distance, which calculates the distance between two points (x1, y1) and (x2, y2). All numbers and returned values should be of type double. Incorporate this method into an program that enable the user to enter the coordinates of the points, then calculate and display the distance by calling the method –distance.
I've tried numerous times to make it work and I'm on the right path, however I'm missing some things in the code to make my results look like this later on, which I've attached onto this post.
I'm having problems with the public static void main(String args[]) part. Everything else is correct before this, my teacher has checked that. I have been trying to research why it won't compile right and can't find any errors.

Create a program to input the length and width of a rectangle and calculate and print the perimeter and area of the rectangle. To do this you will need to write a Rectangle class and a separate runner class. Your program should include instance variables, constructors, an area method, a perimeter method, a toString method, accessor and mutator methods, and user input. Your runner class should include 3 Rectangle objects. One default rectangle, one coded rectangle, and one user input rectangle. All methods should be tested in the runner class.
This is my code:
import java.util.Scanner;
public class Rectangle {
double length;
double width;

View Replies View RelatedMy program is supposed to be used to keep track of inventory for a company. The user is prompted with a menu that asks them which item they want to update and then gives them another menu that allows them to buy, sell, or change the price of the items.

I have spent the past 12 hours on it and have gotten no where. I need to create a program that will calculate different tax brackets. I have tried all combinations I can think of and can't get it to work!!! I am literally about to go insane! I need the program to calculate tax will be 1% for anything up to $50000. If the tax is over $50000, you keep that 1% of $50000 and then add the remaining. So for an income in the second range, it would be 1% of $50000, and then 2% of (income - $50000). This then continues for each range.
The problem I'm having is getting it to display the correct interest rates. I am not asking for you to write it for me. I want to learn. But at this point I have exhausted all resources available to me.
import java.util.Scanner;
public class Project3taxinfo {
public static void main(String[] args) {
final double RATE1 = 0.01; //1% tax on the first $50,000
final double RATE2 = 0.02; //2% tax on the amount over $50,000 up to $75,000
final double RATE3 = 0.03; //3% tax on the amount over $75,000 up to $100,000
final double RATE4 = 0.04; //4% tax on the amount over $100,000 up to $250,000
final double RATE5 = 0.05; //5% tax on the amount over $250,000 up to $500,000
