Hi all,
I have the following function call that returns a string value after encryption or decryption. My problem is how to write this string value to a text file.
String outStr= RunRC4(InputFile,aKey);
try {
BufferedWriter out = new BufferedWriter(new FileWriter(args[2], true));
out.write(outStr + "\n");
out.close();
} catch (Exception e) {
System.err.println(e.getMessage());
}
public static String RunRC4(String InputFile,String aKey)
Can anyone help?
Thanks in advance!!!

Wrong forum. Try asking in web development.

Using Cookies That Are Transmitted by Both HTTP and HTTPS
Because HTTP and HTTPS requests are sent to different ports, some browsers may not include the cookie sent in an HTTP request with a subsequent HTTPS request (or vice-versa). This may cause new sessions to be created when servlet requests alternate between HTTP and HTTPS. To ensure that all cookies set by a specific domain are sent to the server every time a request in a session is made, set the cookie-domain element to the name of the domain. The cookie-domain element is a subelement of the session-descriptor element in the WebLogic-specific deployment descriptor weblogic.xml. For example:
<session-descriptor>
<cookie-domain>mydomain.com</cookie-domain>
</session-descriptor>
The cookie-domain element instructs the browser to include the proper cookie(s) for all requests to hosts in the domain specified by mydomain.com. For more information about this property or configuring session cookies, see Setting Up Session Management.[^]

Good Luck

Hi all !
I want use FreeTTS for my application. I can use the code bellow to read the Hello World in English.
How can i read another language for example German or French,...
My code here :
package com.myprj.demo;
import java.io.File;
import java.io.PrintStream;
import java.util.Locale;
import javax.speech.Central;
import javax.speech.EngineList;
import javax.speech.synthesis.*;
public class HelloWorld
{
public HelloWorld()
{
}
private static String noSynthesizerMessage()
{
String message = "No synthesizer created. This may be the result of any\nnumber of problems. It's typically due to a missing\n\"speech.properties\" file that should be at either of\nthese locations: \n\n";
message = message + "user.home : " + System.getProperty("user.home") + "\n";
message = message + "java.home/lib: " + System.getProperty("java.home") + File.separator + "lib\n\n" + "Another cause of this problem might be corrupt or missing\n" + "voice jar files in the freetts lib directory. This problem\n" + "also sometimes arises when the freetts.jar file is corrupt\n" + "or missing. Sorry about that. Please check for these\n" + "various conditions and then try again.\n";
return message;
}
public static void main(String args[])
{
String voiceName = args.length <= 0 ? "kevin16" : args[0];
System.out.println();
System.out.println("Using voice: " + voiceName);
try
{
SynthesizerModeDesc desc = new SynthesizerModeDesc(null, "general", Locale.GERMAN, null, null);
Synthesizer synthesizer = Central.createSynthesizer(desc);
if(synthesizer == null)
{
System.err.println(noSynthesizerMessage());
System.exit(1);
}
synthesizer.allocate();
synthesizer.resume();
desc = (SynthesizerModeDesc)synthesizer.getEngineModeDesc();
Voice voices[] = desc.getVoices();
Voice voice = null;
int i = 0;
do
{
if(i >= voices.length)
break;
if(voices[i].getName().equals(voiceName))
{
voice = voices[i];
break;
}
i++;
} while(true);
if(voice == null)
{
System.err.println("Synthesizer does not have a voice named " + voiceName + ".");
System.exit(1);
}
synthesizer.getSynthesizerProperties().setVoice(voice);
synthesizer.speakPlainText("Hello world", null);
synthesizer.waitEngineState(0x10000L);
synthesizer.deallocate();
System.exit(0);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
1.So if i want to the program read the "Datum" String in German my code must be change to :
<br />
SynthesizerModeDesc desc = new SynthesizerModeDesc(null, "general", Locale.GERMAN, null, null);<br />
<br />
synthesizer.speakPlainText("Datum", null);<br />
Is it ok or another ways?
2.How many languages FreeTTS support ? which are they?
Best regards !

English is the main language supported and if you want to add another this is what the website mentions:
How do I add support for a language other than English?
This is not a trivial task as it requires a lexicon for the language as well as various statistical data about the language. The document http://festvox.org/festvox/festvox_toc.html describes this is more detail.
from: http://freetts.sourceforge.net/docs/index.php#How_do_I_add_support_for_a_voice_with[^]

Use either Eclipse or Netbeans the latter IDEs show you exactly where your errors are:
1. The constructor of a class has the same name as the class (Line 17).
2. In line 61 you have a typo error in your third equality plus what are you doing with your equalities i.e. what are you using in between them is it an and or an or....
3. In line 69 the same variable cant have many data type.
4. In line 71 the variable your using in the method is hidden from that method so define in it outside the method as either public,protected,private and since your using it in a static method also static.
5. In line 81 to 83 you have a typo error. In line 81 remove the semi colon from the if statement.
Good luck

My advice would be to ask your teacher. Most teachers won't mind if you ask a sensible question, they don't think it's stupid, they think it shows interest in the subject and they should be happy to help. After all, they are there to teach you (in theory at least).
From a quick glance at the code you have posted above, this line does not look right:
if (carChoice==("Ford") carChoice==("Chevy") carChoice.==("Toyota"))
Neither does this line:
if (insurable);
I probably wouldn't do all the work in the constructor, either. If I say much more than that, I'll be doing your homework for you, which I am not going to do.

i want to implement text to speech converter in java. how to do that? can i do it using core java or do i need advanced java to implement it?
i m having it as a final year project.

start making a concept - most times this helps me a lot. 
"text to speech" means you want to convert written text into audio? What kind of text? You will need a person with a clear, smart voice (probably a woman).

Hey guys! So I've been trying to get this utility method to work for a while and can't seem to stop overloading the stack. The method should be able to emulate the Paint Can Tool in MS Paint. It takes a BufferedImage, the x- and y-coordinates of the point to apply the method to, and the color with which to paint the area. My implementation is a recursive one, and I know this is the reason for the overflow, but I haven't done any complex recursive method writing as of yet and don't know how I can fix my problem. Here is the code I've written:
static void paintCan(BufferedImage image, int x, int y, Color color) {
int[][] array = new int[image.getWidth()][image.getHeight()];
for (int r = 0; r < image.getHeight(); r++)
for (int c = 0; c < image.getWidth(); c++)
array[c][r] = image.getRGB(c, r);
changeColor(array, x, y, array[x][y], color.getRGB());
for (int r = 0; r < image.getHeight(); r++)
for (int c = 0; c < image.getWidth(); c++)
image.setRGB(c, r, array[c][r]);
}
static void changeColor(int[][] image, int x, int y, int from, int to) {
if (image[x][y] == from) {
image[x][y] = to;
int left = x - 1;
int right = x + 1;
int up = y - 1;
int down= y + 1;
if (left >= 0)
changeColor(image, left, y, from, to);
if (right < image.length)
changeColor(image, right, y, from, to);
if (up >= 0)
changeColor(image, x, up, from, to);
if (down < image[0].length)
changeColor(image, x, down, from, to);
}
}
This method works perfectly for smaller areas, but when the area selected at the (x, y) point requires too much recursion, a runtime error is thrown. Does anyone know how I can get the method to use less memory and not overload the stack? Help is very appreciated  Thank you!

I did some testing with your code and here are my results:
1. Image size does not effect result.
2. The Pixels in your image cause the stack overflow.
- When your image is mono colored.
- When your image contain n colors in shapes lets say black square, green circle etc...
The above throw the Exception
- When approximately all pixels of the image vary then your code works fine with any size even with 1920 x 1080.
If you want to use the bucket feature in MS Paint here is a simpler way:
BufferedImage image = ImageIO.read(new File("Desert.jpg"));
Color c = Color.red;
int x0 = 10,x1 = 100,y0 = 10,y1 = 100;
for (int i = x0; i < x1; i++)
{
for (int j = y0; j < y1; j++)
{
image.setRGB(i, j, c.getRGB());
}
}
ImageIO.write(image, "jpg", new File("Result.jpg"));
By the way the recursion problem is in the change color method.
Hope this help

I was aware that it was not the image size, but the number of pixels in the shape being filled that was the problem, and that the recursion overflow error was occurring in the changeColor() method... Your solution does not implement the bucket feature in MS Paint, because when you use the paint bucket in Paint it fills all adjacent pixels of a similar color with the color of your choice, what you have given me only fills a rectangle with a certain color :/
Thanks for the reply though!

I think I found the answer guys. My main problem for looking for help with my problem was that I didn't know what the "paint can tool" functionality was called! But it turns out there is something called the Flood Fill Algorithm that is exactly what I'm talking about implementing.
http://en.wikipedia.org/wiki/Flood_fill[^]
|
|
|
|
|
My bad, in my way I was trying to say that if you give the coordinates of the pixels then use the graphics class to fill in the color but its not practical any way here is a nice implementation of the specified algorithm: http://www.cis.upenn.edu/~matuszek/cit594-2005/ Check FloodFillApplet.java and ColorArrayComponent.java
Good luck
