i should be able to use USD, CNY, and JPY. However it seems only the USD ($) will run... doesnt matter which currency symbol the user requests.

I have a form with primefaces input text(p:inputText).Many of the input text values are of the type currency in dollars.When i try to use ,it mandates the user to include $ symbol prepended to the value.Is there any way using which on blur of the field the dollar symbol is prepended and the number gets formatted with proper commas.
View Replies View RelatedI am working on a program where i calculate a fee using a method. I know i have to import the decimal format utility of java. "import java.text.DecimalFormat;" then i have to create an object for the decimal format. With "DecimalFormat f = new DecimalFormat("0.00");" What i am wondering how do i apply it to my system.out.println statement. I know i have to use for instance f.format(calculateFee()); Is that the right syntax for displaying the results because i generate a syntax error that way.
View Replies View RelatedHow in Java to get the current(overridden) currency symbol from the Windows?
As you know t is possible in Windows (Control Panel->Region->Additional Settings->Currency) change currency symbol to the new one.
For example default is '$' and customer change it to the '€'
And programs (Excel for example) use this new currency symbol, i.e instead of $100 you see €100.
I need emulate similar behavior in Java.

I was told to create a class named Billing that includes three overloaded computeBill methods for a photobook store.
The first method takes the price of the book ordered, adds 8% tax and returns the total due.
The second method takes the price of the book, and the quantity, adds tax and returns the total.
The final method takes the price, quantity and a coupon discount, adds tax and returns the total.
All of this I have managed fairly well, although I keep getting a strange error at the end of my program that the constructor is undefined. The problem bits of code(the one throwing the errors) are under the comment //Enter values into each of the methods
Code:
package org.CIS406.lab2;
public class Billing {
//Declarations
double bookPrice;
int quantityOrdered;
double couponValue;

My first thought was to create a constructor for each of the methods that I am using...

I am working through a project in which I am supposed to change dollars into yen with the use of different deposits. I will post the code below that I have been working on.

Just done a quick test to try and figure out the difference between floats and doubles.I made a quick program which outputs the result of 3.3 * 2 as both a float and a double.
I assumed since a float is the larger and more precise of the two data types that there would be more numbers after the decimal point, however this was not the case, it was in fact the double which had more numbers after the decimal point. Result was as follows:
Float: 29.699999
Double: 29.7
BTW for the above code I simply had a few text fields and a button with the following code:
Java Code:
textBox3.setText("" + Float.parseFloat(textBox1.getText()) * Float.parseFloat(textBox2.getText()));
textBox6.setText("" + Double.parseDouble(textBox1.getText()) * Double.parseDouble(textBox2.getText())); mh_sh_highlight_all('java');
Also, as these are limited to a certain amount of numbers im thinking there must be a more precise way for currency, if so what would I use for that? I suppose what im trying to figure out is what data type to use in different scenarios? When to use integer, float, double and long.
I have been working on making a Java application for the Game RuneScape. My goal is to make an Application to where you register on the application and it saves the information in a file. I am also looking to make it so you can transfer money from Runescape to your Account on my Application by submitting a ticket. When you submit a ticket you get assisted by one of the moderators, they trade you in the game and take the money, and then they take that money out of their current account. Admins are allowed to give moderators money via their account or another method. My issue is creating the ticket system. I want to be able to do this all via the application. So basically what i have currently for the application is a chat room, with different rooms available to go into by the users. So I need to make the tickets show up only to Moderators and Admins in the general chat room.
View Replies View RelatedI am working with a JFormattedTextField. After adding the text of the FormattedTextField to an LinkedList i want to read it out and sum it up. So I have a problem to convert the String to and integer...
Example:
23.00 - to 23.00
+ 11.00 - to 11.00
--> 34.00
I have tried it with splitting the string but it didn't work. How to do it?
I want to create a class that converts currency. I stored 2 conversion rate as constant (final) variables. In the main method, I ask the user to enter the amount in US dollars that they want to convert. Then I ask the user to enter the currencyType ("Bitcoin" or "Chuck E Cheese").
However I am stuck in the while loop:
I want to use a while loop that basically does this: If the user entered anything else ( not Bitcoin or Chuck E Chesse), then tell the user to try again, and keep reading Strings until they enter a correct currency type. If the user 3 consecutive incorrect currency types, then exit the program.
Take a look at what I have so far.. when I run the program it does not quite do what I want it to do Also, there's something wrong with one of my if statements and I want to figure out how to fix it.
Java Code:
import java.util.Scanner;
public class CurrencyConverter
{
public static void main(String[] args)
{
System.out.println("----------------------------------");
System.out.println(" Currency Converter");
System.out.println("----------------------------------");

This is how I want my project to look like:
So I currently have working code that calculates the denominations that I need when change is displayed. The problem is that it seems to be missing one cents every time. So if my change prints out $12.35, it will end up being 1 - ten, 2 - ones, 1 - quarter, 1 - nickle, and 4 - pennies rather than 2 nickles. or 1 dime This happens for any dollar amount unless it is even cash and no change, or the change calculates to where there doesn't need to be a penny. Just an FYI, this code is being used in a GUI panel program if it seems strange in anyway.
int change1 = (int) ((total - realTotal)*100);
num100 = change1 / 10000;
change1 = change1 % 10000;
String dollar1;
dollar1 = String.valueOf(num100);

I am new to programing and I am making a dice game where I have to roll two dice and add the total together for each dice (2, 3, 4 ect.) I have all the program finished except one thing.
How would I use the * character that shows the total percentage each number was rolled. Each * will represent 1% of the total rolls. Instead of saying there were ( 4 ) 2's rolled i have to put ( **** ) 2's rolled.
2: ***
3: ******
4: *********
