Alright, so let's say I have this string. I want to make it so that the string for this variable has to follow a certain format.
For example, "AAA-B", where the A's are a digit 0-9, the - is always in the same spot, and B is a letter but only from A-M. All of this for a single instance variable.
Is this possible? How could I go about doing this.
In the Employee's toString, you are using the NumberFormat class to format your hourly rate and weekly pay but you are supposed to use java string formatting only (%f). You should change those to use only string formatting - no use of NumberFormat.
package coursework;
import java.text.NumberFormat;
public class Employee {
private String firstName;
private String lastName;
private int employeeId;
private double hourlyRate;
public Timecard timeCard;

I'm trying to insert some data of type date into database table using hibernate.i take the input date from an xhtml form as shown below
addEvent.xhtml
Event Date (dd-mon-yy) :

p:type="date"/>
<p/>
<h:commandButton value="Add Event" actionListener="#{eventBean.addEvent}" />

This is my addEvent method in EventBean.java

uname = Util.getUname();
boolean a = EventDAO.add(this);
if ( a) {

While executing this..i get the following error: ORA-01861: literal does not match format string. Could it be due to any mismatch in date format (chrome browser automatically takes date in the format mm-dd-yyyy )? If yes, how do I resolve it? (I'm using Oracle database)
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000"

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

I am working on a project that just calculates simple interest based upon a principal and a percent interest rate written as .xxxx from user.
I need the Loan amount and the final interest calculation to show up as a currency with commas in appropriate areas, the Rate to be expressed as X.xxx% instead of .xxxx
I keep getting this error when I compile:

why the default date format that the textbox accepts is in 'mm/dd/yyyy'.For example if i entered "13-05-2014" then it would return an error stating date is invalid.If i entered "12-05-2014" then it would return "5 Dec, 2014".I did not declare any dateformat anywhere except for the datepickers which as shown above, is 'd MMM, yyyy'.Before this happened i trialed and error many different kind of codes to try to validate the date however it all didnt work and so i reverted it all back to the original codes.Last time the dateformat that the textbox accepted was 'dd/mm/yyyy' and it worked fine with my javascript function except the validation part.
Now it still works except that the dateformat changed to 'mm/dd/yyyy'.I did try to use console.log to find out what's wrong but there were no error messages.Why has the dateformat changed by itself?

When trying to convert the time zone of a date I encountered the log below. java.lang.IllegalArgumentException: Cannot format given Object as a Date..Here is what my code looks like:
1. First I will get the date from the email header by the following code.
String messageDate = (String) mail.headers["Date"];
Output: Wed, 4 Jun 2014 18:30:05 +0800
2. Next I will convert the timezone to EST.
SimpleDateFormat timeZoneConvert = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z");
timeZoneConvert.setTimeZone(TimeZone.getTimeZone(" EST"));
String l_MailDateEST = timeZoneConvert.format(messageDate.trim());
Once the code run I encounter the said error.

im making a javabean for stopwatch which works perfectly, but i want in the property descriptor format, so the user can change its format.
currently i have;
private String displayFormat = "MMMM d, yyyy h:mm:ss";
private SimpleDateFormat formatter;
public synchronized void setDisplayFormat(String newFormat) {
String oldFormat = getDisplayFormat();
try {
formatter.applyLocalizedPattern(newFormat);
timerHasPinged();
[code]....
currently the timer works its format is in 00:00 minutes:seconds, but i want it to start as MMMM d, yyyy h:mm:ss, for example March 17 2014 00:00:01, so only one second has passed here. i believe the set and get format method is fine but the timerhaschanged needs to change as this is where the format takes place.
I am using NetBeans IDE 8.0.2 to program Java code. I am a beginner in Java.
Instead of getting two decimal places after the point, I am getting three despite using the code format for two ("##.##"). Actually, this happens even if I remove the format code between the quotes. It is as if the program cannot see the format code. Why this happens ?
Here is the relevant program code:
private void convertButtonActionPerformed(java.awt.event.Action Event evt) {
double inputNumber = 0;
// sets the decimal format

I have inherited some code that is supposed to work just fine. The trouble is that when everything is rebuilt on my desktop, the projects crash. They all seem to crash at one particular part of code.

The project is to basically make a song list, or playlist, and be able to sort it and search for songs and crap like that. The program works fine, but I want to have it print the playlist in a nice looking format. Here's how it looks now...
Amount of songs in playlist: 7
Current playlist:
Title Writer Singer Year Duration Genre
Back in Black AC/DC Brian Johnson 1980 4.18 Heavy Metal
A Call To Arms For Today Mattie Montgomery 2014 3.47 Religious
Fade To Black Metallica James Hetfield 1991 6.53 Metal
In The End Linkin Park Chester Bennington 2000 3.36 Other
Monster Paramore Hayley Williams 2011 3.2 Alternative
Over My Head The Fray Isaac Slade 2005 3.58 Rock
Through The Flames War of Ages Leroy Hamp 2008 4.2 Rock
The only reason the Title, Writer and Singer listings are lined up is because I manually spaced them out by guess and check method...I guess you can figure out how fun that would be with 20+ songs. So what I'm wondering is, is there an easier way to put this in a nice format where everything lines up? Kind of like how iTunes displays things.
Basically, I have three classes. Song, SongList and a Tester class. SongList takes various Song objects (the Song class defines one song with a title, write, singer, etc..) and puts them into an ArrayList. Then there's various methods for sorting by writer, sorting by genre, swap songs, etc. in the SongList class. Tester class just runs through an example of how everything works.
