JSF :: Append Dollar Symbol And Format Comma Of Currency Value In Input Text
Feb 17, 2014
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.

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'm using one method to take input from the user and append some text to it, then I am trying to return the value of the variable and use another method to print it out. But for some reason whenever I try doing this I can't print out anything and I only get a "null" output. Why this is happening?

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 am supposed to write a program that calculates the total annual compensation for a salesman using user input for the salary, sales, and commission rate (list of 3 predefined commission rates. have to display in dollar format the amount of commission and total annual salary.
CommCalc class
public class CommCalc
{
//attributes of class, stored data
private double sales;
private double salary;
private double rate;
//and a total field? beware stale data.
//store sales argument from sales field
public void setSales(double sal)
[Code] ....
I know that i have to fix some of the semantics . I have this code that I made earlier, is there an easy way to make it into a GUI interface? Or will I have to go throughthe code lines to add the JOptionPane? And I am a little confused on how to make a list (array) for the commission rate.

Here's a link to it : [URL] ....
The basic gist is it's "A program that reads in a text file that uses a specific input format and uses it to produce a formatted report for output."
Specifically :"For this lab you will write a Java program that produces a simple formatted report. The program will prompt the user to enter a file name. This file must contain information in a specific format (detailed below). Each "block" of the file contains information for one player in a competition -- the name of the player followed by a number of different scores that that player achieved. The program should find each player's average score, median score and best and worst scores and display them in a line on the final summary report. The program should also determine which player has the highest average score and which player has the lowest average score."
I get the following errors when I try and compile it:
Enter an input file name: Project11.txt
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException... -1
at java.util.ArrayList.elementData(Unknown Source)
at java.util.ArrayList.get(Unknown Source)
at Project11.getMedian(Project11.java:68)
at Project11.main(Project11.java:27)
I get that the error(s) reside in lines 68 and 27, among problem other areas, but I'm not exactly sure how I can fix them.
Here's my code:
import java.io.*;
import java.util.*;
public class Project11 {
public static void main(String[] args) throws IOException{
Scanner in = new Scanner(System.in);
System.out.print("Enter an input file name: ");
String input = in.nextLine();

How to output text to a file, so I had to do my own research on google, but the results I found were confusing. I finally got my code to write to a file, but I cannot figure out how to append a new line. I know what part of the code is incorrect, but I don't know how to fix it. here is what I have right now:
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Scanner;
public class highscore {
public static void main(String[] args) throws IOException {
[Code] ....
I can see the last two lines are telling the program to overwrite the first input with the second. Of course if I pick a different file name for the second output, I get another file with the second input, but I need to learn how to append as well.

Is there anyway to format my input file "IF1.txt" into an excel/csv file, but with the content rearranged into a desired format? (all of this has to be done by a java program)
Here is the input file IFT.txt:
R1 : Integer,3 Food
R2 : Integer,3 ID
R3 : Integer,3 Temp
R4 : Integer,3 Weight
R5 : Integer,3 Age
R6 : Integer,3 Length
[code]...
Desired Output:
TIME Food ID Temp Weight Age Length
00:00:00.001 1 0 0 0 0 0

I decided to code this quiz I took in class about asking the user to input a string and the code is suppose to check for upper case letters. If a upper case letter is found, it should increase a count by one. Once the check is done, it should display the number of uppercase letters. For some reason I am getting this weird compile error stating that symbols can't be found...
Java Code:
import java.util.*;
import java.lang.*;
public class StringCheck{
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.println("please enter a string: " );
String s = input.nextLine();

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;

I am trying to do is extract numbers that are in word format in a long String, i.e. a song, and return each of their numerical values, in order to add them all up. So I'd like to calculate the sum of all of the numbers in the text. This has to work for any piece of text and for all numbers up to a trillion.
So I broke the string down into tokens and stored them in a String []. And I divided up the possible numbers in word format into:
LARGEST: thousand, million, billion, trillion
HUNDRED: hundred
TENS: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
UNITS: one, two, three, four, five, six, seven, eight, nine
SPECIALS: ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
I believe that these are the only words that it will need to recognize. I began reading the tokenized string from right to left and then when I came across a unit, special or tens as the first number I hit, I would then set it's numerical value and check if the word before was also a number and whether to add or multiply etc. i.e. First number hit is a two, if the number before is sixty, then I would just add it to sixty and check the word before that and so on.
However, when implementing it, it seems like an extremely long way around it. How I could implement this in a swifter manner? An example of it working would be:
"Nine Million rockets turned Three times and met Twenty Two Aliens", it would extract, Twenty Two as 2, then 20 = 22, then extract Three as 3, and then Nine Million as 1,000,000 x 9 = 9,000,000
9,000,000 + 22 + 3 = 9,000,025

The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.

I was working on my personal project when I realized I needed to split a string and extract 2 elements of it. The way it works is the user enters 2 numbers separated by a comma like this: 4, 8. Then I want to put the first number into a veriable called x and the next number into a variable called y. How can I do this?

The question is we have to write a class named Coin. The Coin class should have the following field:
A string named sideUp. The sideUp field will hold either "heads" or "tails" indicating the side of the coin that is facing up.
The Coin class should have the following methods:
A no-arg constructor that randomly determines the side of the coin that is facing up ("heads" or "tails") and initializes the sideUp field accordingly.
A void method named toss that simulates the tossing of the coin. When the toss method is called, it randomly determines the side of the coin that is facing up ("heads" or "tails") and sets the sideUp field accordingly.
A method named getSideUp that returns the value of the sideUp field.
Now we have to create a game program using the Coin class. The program should have three instances of the Coin class: one representing a quarter; one representing a dime, and one representing a nickel.
When the program begins, your starting balance is $0. During each round of the game, the program will toss the simulated coins. when a coin is tossed, the value of the coin is added to your balance if it lands heads-up. For example, if the quarter lands heads-up, 25 cents is added to your balance. Nothing is added to your balance for coins that land tails-up. The game is over when you balance reaches on dollar or more. If your balance is exactly one dollar, you win the game. You lose if your balance exceeds one dollar.
I think I've completed the Coin class but the game program is giving me problems. I got it to add the balances when they land on heads but it only does it one time. I'm trying to figure out how to input a loop but I haven't had any luck.

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.
