Thank you. I'll try your recommendations.
P.S.: I was using printf method because it was recommended in the practice of the book I studying with (Core Java 2).

anyways i have been trying to solve this question .. the question goes as follow:
Q: Write a program that fills the component with a large ellipse, filled with your favorite color that touches the window boundaries. The ellipse should resize itself when you resize the window.

how to make it touch the window ?
easy 
draw it of the size of the component, and be sure the component is of the size of the window (in your window, add a panel, on which you can draw directly)...
if you place the drawing code in the correct event handler, (overload paintComponent(Graphics)).

according to documentation [^]
strValue = strValue.replace(',','+');
should do the trick.

create a class toy collection that stores information about different toys in a toy shop. The information to be stored about a single toy is,
- toy identification as string
- name of the toy as string
- Short discription about the toy as string
- Price of the toy as float
- Quantity of the toy in hand as short integer
This class contains following methods,
- Constructor method that assigns user input values to above mantioned variables.
- main() method that creates array of 4 objects of toycollection class and that takes input for all about details from the user end
class method to check validity of Quantity and Price values. If all values are valid then create the object and display the details for all 4 toys.
- Method that checks validity of quentity and price. If the quentity is 0 or negitive then method should through a user defined exception with approriate message and come out of program. Similiry if the prize is 0 or negivity then it should through user defined exception with appropriate message and come out of the program.
- Method that displays all detail about a single toy in the following format, e.g. Here Total price should be calculated
Toy Identification : S-1
Toy Name : Small Scooter
Toy description : Ordenery 3 wheeler Scooter
Toy Price : 650.50
Quantity in hand : 3
Total price of Toys : 1951.50

such an exception typically occurs when a user-defined class you're using (a class of yours then) cannot be found by the JVM.
To solve that, check your classpath.
Just a guess : why don't you use an IDE (Eclipse is pretty cool for java !! you should have a look at it) ?
BTW, Do you Example class references any other class defined in another file which the compiler wouldn't know about ?

My guess is '.' would be missing in the classpath.
As in aforesaid reply, its good to use IDE like Eclipse.

Hello,
I've only dabled a bit in Java, I work almost exclusively with .Net. That being said, I am looking to do encrypt a string from a java application (this will be done by another developer), decrypt it in .Net and send an XML response to the the java app.
Is there a universal method for encryption in Java that would allow us to use the same encryption key/method?
I know how to encrypt/decrypt in .Net, I just need to know if there is a standard that is used by both frameworks?
|
|
|
|
|
FYI - (in case anyone is interested)
I just used standard DES encryption which worked out great for my situation. As long as the same rgb/rgbIV keys are used on both ends, the entire process was very painless.

if we have a tree that contains int.
I want to find the largest subtree, in a sense that it (subtree)has largest sum of the values of the nodes
Any idea, codes??
Thanks
P.S.

I think you need to clarify your question. E.g:
1. Are you talking binary trees here?
2. Do you mean you want a method to test which childnode of a given node that together with its childnodes has the largest sum of values?

you already asked that yesterday.
it's a forum, not a chat.
so please read the forum guidelines, and be patient.
also, know that if you don't be efficient answers, maybe it's because nobody knows, or because you asked the wrong way with too few infos, etc...
