I am getting the following error:
Exception in thread "main" java.util.MissingFormatArgumentException: Format specifier '.2f'
The line it is referring to is:
System.out.println("
Toppings: ");
for (int i = 0; i < toppings.size(); i++) {
System.out.format("%-15s£%.2f
",BBQSpecial.getToppings().get(i)
.name(), BBQSpecial.getToppings().get(i).getCost());
What is the real purpose of using Protected access specifier in Java?

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'm trying to put together a method that formats telelphone numbers, but there's a part of my code that not working. If I enter (305)912-5458 into the variable phoneNumb I get an index is out of range error. I added a lot of system out messages so that I can try to get an idea of why the code was crashing.

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?
I'm doing a project in JSP and Oracle..Here in my project there are two types of department.. Accounts and Sales..

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.
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.
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.
I pass it a string and the "getResource" or "getContentClassLoader" is failing.

I guess one way to tackle this is to break it apart into segments.

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.

Write a program that reads number between 1,000 and 999,999 from the user and prints it without a comma separating the thousands. Read the input as string. Find the length of the string and use the substring to break it into two pieces. Do not include the comma. You can then concatenate using the + symbol to reassemble without the comma. For example if the number is 123,456. First would equal 123 and second would equal 456. noCommaNumber - 123456.
I do not think it is required to only allow numbers in that range in the code. My question is how to get the first half of the number before the comma in a string to make the last line work. What I think is not doing what I need is the line String first = numberIn.substring(numberIn.indexOf(",", 0)); This is just the last thing I tried.Getting the second half is done using IndexLastOf method in the substring class javaforumquest.jpg
