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 { public static void main(String[] args) { double mealPurchase = 0; mealPurchase = Double.parseDouble(JOptionPane.showInputDialog(nul l, " Enter meal total: "));
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
import java.util.Scanner; public class Bill { public static void main(String[] args) { Scanner console = new Scanner(System.in); //final variables Premium Service final double monthlyChargeP = 25.00; final double FordayminutesP = 0.10;
[Code] ....
I can't find the syntax on {} my block is highlighted red in my application
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;
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.
I am working on a text based adventure game. (This is NOT OOP at all) The problem comes in at my second if statement inside my loop, it is not adding 1 to my array locations[] it keep printing location[0] then a 1 at the end. Not really sure what is going on here. I would like it to when I type "Go north" it adds 1 to locations[]
E.G locations[0] Go north locations[1] go north locations[2] package com.PenguinGaming; import java.util.Scanner; public class Game{
I'm really struggling adding JLabels to my GUI. The code is giving no errors but the JLables aren't showing up as I think I've done something else wrong. Here's my method for adding the JLabels:
public void showGraphics(){ for(int i=0; i<message.length(); i++){ if(message.charAt(i) == '#'){ JLabel localLabel = new JLabel("test label"); getContentPane().add(localLabel); } } }
I think the problem might be to do with how the rest of the GUI is setup and the fact that I haven't specified where to add the JLabel just that I'm adding them.
The serializable class ImagePanel does not declare a static final serialVersionUID field of type long public class ImagePanel extends JPanel{ ^^^^^^^ ^ ^^2 problems (1 error, 1 warning) mh_sh_highlight_all('java');
im basically just trying to put the image inside the GUI and centre the text underneath it. Which is hard to believe since the text is above the image in the code .
I have a supermarket checkout line where i have a list of available products on the left and then a basket on the right with the products in. The products are listed in an array, here is the product class
public class Product { private String name; private double weight; private double price;
[Code] ....
with getters and setters excluded, and the list these are put into
public class productList extends DefaultListModel { public productList (){ super(); } public void addProduct (String name, double weight, double price, int code){ super.addElement(new Product(name, weight, price, code));
i have the price for each product to be displayed in a text field with the following code
addBasketItem = new JButton(); getContentPane().add(addBasketItem); addBasketItem.setText("Add >");
[Code] ....
defaultCheckoutList contains my available items and defaultMainList is the basket, with mainTillPrice being the jtextfield.
This works to get the price however it just replaces each time i make a new entry with the price for the next item, i want a total of the price of all the items i have added, but not sure how.
I want to be able to check that the data for the ID is limited to a certain collection of characters formatted in a certain. For example, I may wish to limit it to 5 lowercase letters or numbers, or a combination of both. How could I do this?
Here is my program. I have to add the outputs from variable 'done' together. It seems to not work inside or outside the loop.

I am doing a few Spring tutorials and in eclipse and for each tutorial I have to right click my project, build path, and then add external archives and then select the spring JAR files I want to bring in and use before my project will successfully compile and run. I was just wondering is this required for every project or is there a way I can set eclipse up to look in these locations for every project without me having to explicitly tell it too?
I have been trying my hand at making 2d top down view games and have found myself repeatedly using the same code so i created a file with all the functions so when it is down i just import the jar and dont have to keep rewriting functions. I have trouble because the background is loaded on the screen and i dont know why as i didn't tell it to load. In fact I set the panels visiblity to false. Both of my classes are in the same package. Why I still get the Image.

I am trying to add two bytes together in binary. The problem is that I need to print the carryover also. The printed result should be 8-bits long if the byte or the integer converted in binary is less than 8-bits the empty space should be filled with 0-s. I figured out how to print and add them, the part with the filling the blank with 0-s too. how to print the carryover. For example:
byte x =15; byte y =9; the output will be :
00011110 - carryover x 00001111 y + 00001001 __________________
00011000 - result
import java.util.Scanner; public class Addbytes { public static void main(String args [])
I am new to swing and I wanted to know how to be able to make a second row of buttons. Right now I have a text pane at the top and at the bottom one row of buttons. But I need to add another row or two of buttons. I've only been coding in Java.
public class TextPane { public static void main(String[] args) throws IOException { ///////////// //I/O FILES// ///////////// //Create the input file FileWriter inputFile = new FileWriter("userInputStory.txt");//story user creates with the <nouns>, <verbs>, etc PrintWriter inputFileWriter = new PrintWriter(inputFile);
So I'm doing a basic MVC layout for a pretty basic game that I am making in order to understand the whole MVC layout. The game requires the user to move up/down/left/right via JButtons on the GUI. Since I'm using an MVC layout and my buttons are in a different class than the ActionListeners, I was wondering what the best way to add the action listeners are?
Method 1:
View Class ActionListener method: Java Code: public void addMovementListeners(ActionListener u, ActionListener d, ActionListener l, ActionListener r){ moveUp.addActionListener(u); moveDown.addActionListener(d); moveLeft.addActionListener(l); moveRight.addActionListener(r);
[Code] ....
Which method is better? Is there another method that is even better than these two? Trying to get this MVC thing down.
I am making a graph to implement Breadth First Search and Depth First Search. I changed the program because I want each button to be its own node. However I am having an issue placing them into a panel. When I run the program I get the following error:
The method add (Component) in the type Container is not applicable for the arguments (Buttons)
JPanel matrixPan(){ Buttons[][] matrixBtn = new Buttons[25][25]; JPanel panel = new JPanel(); panel.setSize(550,550); panel.setLayout(new GridLayout(25,25));
