Convert Currency Instance To Integer
Jul 26, 2014
I 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("----------------------------------");
[Code]...
This is how I want my project to look like:

I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:
Java Code:
public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

If I use the class DecimalFormat to format long number, how can I convert it back to integer?
DecimalFormat longFormat = new DecimalFormat("#,###");
long testLong=11000;
String strLong=longFormat.format(testLong);
System.out.println("NUM : " + strLong);
//Assume that at this point I don't have
//testLong, I have only the strLong value...
long newLong=Long.parseLong(strLong) * 2;
//java.lang.NumberFormatException: For input string: "11,000

So I have to write a java program that converts hexadecimals to decimals without using the whole "integer.parseInt(AB1, 16)" method. I tried looking up how to do this but every forum/site I went to used this same method.

I am using a static method to convert a string to an Integer object. Next using a instance method to convert Integer object to an int.
Compiler is giving me two "cannot find symbol" errors:
One pointing to the dot operator between "Integer.valueOf(s)"
The other pointing to the dot operator between "obj.intValue()"
I have latest JDK installed: jdk-7u51-windows-x64.exe
Looks like JCL installed correctly with rt.jar file located in "lib" directory under "Program Files"
Following is source code:
Java Code:
public class StringToInt
{
public static void main (String args [])
{
String s = "125";
Integer obj = Integer.valueOf(s);
int i = obj.intValue();
i += 10;
System.out.println(i);
}
} mh_sh_highlight_all('java');

I am writing a program to convert a base 10 integer to any base 2-16. Here are the terms:"The method is to convert the decimal value the user selected into whatever base the user selected and print the converted value one place value at a time by using an index into an array of characters 0-9 amd A-F that is initialized to contain those characters.In the method you will find the largest place value (i.e. power of the base) that will divide into the decimal number.
Then you can set up a loop that will operate from that power down to and including the 0th power to determine how many times each place value goes into the decimal number. Using the loop counter, index into the character array to print the character that corresponds to the quotient number and then subtract the product of the place value and the quotient from the decimal number. With the power (loop index) decreased, repeat until you finish the 0th place value. Here's what I have so far:
import java.io.*;
import java.util.Scanner;
public class ConvertIt
{//start program
public static void main(String[] args)
{//start main
Scanner input = new Scanner(System.in);
System.out.println("Enter a positive integer from 0 to 10000.");
int number = input.nextInt();
[code]...

I've Parent and child(extends Parent) class To initialize the constructors, I'm injecting from google.juice#injector. Let me show the code,
Parent.class
public class Parent{
private Animal animal;
@inject
Parent(Animal animal){
this.animal = animal;
[code].....
When I do this, ClassCastException is happening. Why is it so? Is there any way to convert instance of parent to child instance.

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.

Java Code:
package billing.util;
import java.math.RoundingMode;
import java.text.NumberFormat;
import java.util.Scanner;
public class CurrencyFormat {
private static final int USD = 0;
[Code] .....
I should be able to use USD, CNY, and JPY. However it seems only the USD ($) will print... doesnt matter which currency symbol the user requests, only the $ will be reprinted....

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.

How 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.

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);
