thank you,
here is the file

Hi, thanks to both. That solved the problem although I still don't quite understand.
Cgeier, the thing is, the NullPointerException doesn't come when it's finished reading the original file. It...

I'd appreciate if somebody could have a look at this code and tell me where the problem is.
The program is meant to take a .txt file and split it in three different files: one with words of 1 to 4...

Have a good sleep and then have a look in the trails (http://java.sun.com/docs/books/tutorial/java/nutsandbolts/index.html)

Raik.48,
welcome to the forum. Please next time use code tags when you post code.

When you make a call to calcArea() method the area is calculated as it says in the method. When you call...

axelle,
if your problem is how to use NetBeans IDE take a look at the tutorials (http://www.netbeans.org/kb/index.html).
Gook luck,

ah! right! now I see why I never got into a club!

ah!, it was too late in the morning!

I'm guessing that by "the number of alphabets" you mean the number of letters your word has. If I'm guessing wright then use length() method of the String class.
Hava a look at the String ...

and your problem being...?

newjavastudent,
as it's coded, you just have to break your while loop with ctrl+c while the program is running and once you've finished writing whatever you'd like on the new generated file.

wendellrob,
if you make all your variables and the computeNetPay() method static you'll be able to access them from main() (that should be also static). Since your variables are static you don't...

Thanks, sneaker.
That did it.

Hi,

I'm trying to print a string on the center of a window using GridBagLayout.
All I see printed is a part of the string I expect (the current month) instead of the whole string.
I don't seem...

hi valleymorning.
Perhaps an idea would be:
1. split the 6 digit number in two: divide the number by 1000 and put the result as an int into a variable (say firstPart). Find the modulo 1000 of the 6...

So, where's your problem? finding the algorithm or coding it?

wait a minute!
akulkarni: did you try to compile and run it? did you run it several times with diferent strings?
Try inputing "naan".
What happens?
Bulls: 0;
Cows: 3;
What happens with "nana"?...

Daiva,
it does the trick.
I wouldn't have add an unnecessary member to the array, though. Instead I would have called the correct one when you need to call it. But this is just my opinion.

Daiva,
did you read what javaAddict mentioned about arrays being zero based?

latinajoyce,
just a small addition.
In your problem description you tell us you need to choose numbers between 1 and 10. However your code chooses numbers between 0 (included) and 10 (excluded)....

No worries

javaAddict,
if a problem is marked as solved I don't normally look at it anymore. It's helpfull because I can look at other problems instead.
True, perhaps I was being selfish and should have...

OK, congrats, you got your code running.

Will you please mark it as solved?
That'll be of great help. Thanks

did you compile it and get any errors?

OK, thanks to you both, that helped a lot.
I've been doing some more reading and inserted a new line of code after the while loop int count = d.getComponentCount();. It actually returns only one...

Lokth,
a possible solution could be to put every digit of your int answer variable on a int[] (to do that you could divide the number by 10, put the modulus on the array, divide again the result by...

Thanks VernonDozier.
The code as I showed it runs. After you answered I just noticed there are dozens of nullPointerExceptions showing on command line as in

Exception in thread "AWT-EventQueue-0"...

true, true.

Lokth,
can't you put an if statement saying if input equals h then give hint?

Something like,



String inputString = String.valueOf(input);
if (inputString == "h") {
// give hint function

Hi,
I'm starting working with the Graphics and related and strugling to understand it.
I'm trying to do something as simple as drawing a String on a panel. The string changes on runtime. I post the...

Oh, sorry VernonDozier, I didn't see your answer.

akulkarni,
in loop on line 30 to 36: Think what happens when i == 3... you need to reset j to 0. That way you check letters before variable i.
try


for(int j=i+1;j>3;j++) {
if (j>3) j = 0;...

Hi, thanks Ezzaral.
Yeah, you are right, fiddeling with setFirstDayOfWeek(int) sounds messy.
I was trying to find a way to change the Locale and hoping that all the rest would change automatically...

Hi,
I'm trying to understand how the Calendar, GregorianCalendar and Locale classes work.

Say I instantiate two Locale objects and then two Calendar objects, each with their respective Locale.

You'll have to give some more details and some code to chew on.

@sam_inquisitive, chill out man! Nobody told you were going to ask for implementation, it's just that we've all seen in here what Salem said. Surely Salem didn't mean it personaly.
Anyhow, Salem's...

Yeah, I'd like to know too. Also, if the problem is solved, could you please mark it as solved?
Thanks

Oh, yeah and I forgot, have a look to
