Im a 14-yers old programmer whos leraning Java. In my Lerningbook there is a question I cant answer: how i can write a program which give the first 100 "Quadratzahlen" (Im a stupid german, i can speak english very well but i dont now some words) on the flat out. after 10 "Quadratzahlen" the user must type enter to continue the program? How i can do this? Please help the stupid german and his bad english know-how!

"Square number." Do you know how to calculate those? A number multiplied by itself.
You need a for loop (since the task spells "counting"), and you also need to read from System.in to make the console output stop and wait for the user to hit enter.
@OP. You are young, and I guess that you are trying to learn Java because you want to create something. Why are you trying to solve the boring exercises? Why not just do something fun? E.g. try to create a simple game, like guess the number? (And then just use the book to look up things)

Okay, you need to know what a for loop is. So, read up on that. Your book should treat it a lot. Also, the easiest way to get the square (which is what "quadrat" means in english) of a number ("zahlen") in Java is just to multiply it by itself:
x * x
So just put it in a for loop from 0 to 99 (I'm assuming they mean for you to use 0 and the positive numbers, since there really are no first 100 squares) and print out the square of each number using System.out.println. Use an if statement to check if it's the 10th run through the for loop. If so, then you'll check for the user to push enter. If you're not sure how to do that, ask.
Also, if I mistranslated Quadratzahlen, then the code above may be wrong, but maybe you can verify that that's correct?
I wrote my first Console-Program just fun. Its not perfect, but its good to use(I hope you understand what o mean!) Its a program which answer the user for his name/surname, username, passwort/retype passwort (and IF the retyped-Password is not correct, the program gives a "Fehlermeldung" out.)
and for the password who i set. And IF this Passwort is correct, the user ask for
transfer the dates. ELSE the Prgoram stop.

I am too lazy to refer to my books. It has been four years since I last looked at German.

I've never seen Babelfish give two meanings before. I've seen it translate things strangely, especially idioms.

They might be changing some code to make it generic. :D

Check your ground wire; it seems a bit wobbly; the baud rate, parity
and start/stop bits settings look kind of ok.

I don't think so. That's why I'm so surprised. I didn't know that he approved schools :)

"He"? Annie is most definitely a very admirable "she", no doubt about it.

I'm either dyslectic, or to weak to push the keys. I've seen that I quite often miss some characters.

From what I remember from an old French girlfriend I met during the
holidays once and my French lessons at highschool, this means quite
something else ...

It's a stack problem. OP stacks have but three slots:
Phase 1: start
[slot 0] Matter
[slot 1] empty
[slot 2] empty
Phase 2: trouble
[slot 0] Trouble
[slot 1] Matter
[slot 2] empty
Phase 3: phrase trouble & post
[slot 0] Phrased question
[slot 1] Trouble
[slot 2] Matter
Phase 4: acknowledge answer
[slot 0] Answer
[slot 1] Phrased question
[slot 2] Trouble
*plop*
Phase 5: what was this all about again ?
[slot 0] Matter
[slot 1] Answer
[slot 2] Phrased question
*plop*
Phase 6: what was the trouble again ?
[slot 0] Trouble
[slot 1] Matter
[slot 2] Answer
*plop*
Phase 7: What does this answer mean ? What did I ask again ?
[slot 0] Phrased question
[slot 1] Trouble
[slot 2] Matter
*plop*
Phase 8: Ah, yes, so, now, what did he say ?
[slot 0] Answer
[slot 1] Phrased question
[slot 2] Trouble

Et caetera. It's cyclic. The body reacts with fear, and runs off yelping.

That Sir, is one funny stack you've got there.

Just two questions Sir:
1) Is your Stack class inflatable?
2) If not, can your funny slots contain any ScantilyCladWoman?
3) where's the javadocs of your class?
kind regards,
Jos

I just checked with our technicians, they say no, 'cause it's made of thin air and would thus explode. We have a pink version, though. Strawberry flavoured. The one I posted was our brand new flavour: we call it "dung". Lick your screen and you'll see. Well, taste, that is.

Certainly, sir. But only on mondays, when their spouses are at the bingo club. And you don't fit as a ScantilyCladWoman. Don't even dare think of trying.

You said two questions, sir.
Hi

i dont want to use any datatable.i am using panelgrid.
i want to add some componenets dynamically to a page. here is my code i am not able to undestand how to do.
