I have to calculate auto and cross-correlation from a file, like this:
Rxx(n)= 1/N* SUM[from k=1 to N-n]((x(k)-x(mean))*x(k+n)-x(mean))
and after
Rxy(n)= 1/N* SUM[from k=1 to N-n]((x(k)-x(mean))*y(k+n)-y(mean))
I've 600 x an y,
k = the numbers of x (N is the last one)
n = 0....N-1

I am working on a project named as "Auto Click and Populate". This is link is like online feedback form / surveys which we program. I have a link with me which is mentioned below and there will be a counter box which will hit the link that much number of times.
Inputs:
-A text box having this link.
-A numeric box having counter number i.e. the number of times the link should be processed.
-A button named as process which will INITIATE the process.
Now say if I input 10 into the numeric box; the attached file contain link should be processed 10 times and the question which is coming on the link should be answered randomly out of the options which are present. For ex: When you will hit a link; the first question will be gender in that 3 options are present "Male", "Female" and "Prefer not to answer"; either of 1 out of 3 should be punched automatically and proceed automatically ahead. The punch(es) will be stored in database which is maintained at my end.I have done research and till now found the code for auto click only and not for auto process.
I need to create a diagonal cross however I can not figure out how to do the upper left side of it.
Currently I am getting

0*------*
1 *--*
2----*

I need fixing an issue in the search textbox in one of the jsp's. I was informed that cross site scripting can be done in the textbox and I kept the below code in my jsp to fix the issue:
Java Code:
searchTerm = request.getParameter("search");
searchTerm = searchTerm.replaceAll("<", "<").replaceAll(">", ">");
searchTerm = searchTerm.replaceAll("[^A-Za-z0-9 ]", "");
searchTerm = searchTerm.replaceAll("eval((.*))", "");
searchTerm = searchTerm.replaceAll("["'][s]*((?i)javascript):(.*)["']", """");
[Code] ....
Now, after applying the above code, the cross site scripting can be done and the problem is that the search can't be done using the textbox and all the time will display none results.
The program I'm supposed to create generates a random number between one to ten. Then the program is to ask me if I wish to cross the road.
If you choose to cross, the outcomes for 0-2 are "You crossed safely."
For 3-5, 75% of the time it should say "RIP you got run over", and 35% of the time it should say "You crossed the street."
For 6-8, 60% of the time it should say you made it.", and 40% of the time it should say "You died". For 9-10, it should say "RIP".
So far I have gotten the random number generation part working,
import java.util.Random;
public class test4 {
public static void main(String[] args) {
Random random = new Random();
for(int i =0; i < 1; i++){
int num = random.nextInt(10) + 1;
System.out.println("The number of cars on the street are: " + num + "
Do you wish to cross the road?");
}
}
}

the prime numbers from 1 to 2500 can be obtained as follows. From a list of the numbers of 1 to 2500,cross out al multiples of 2 (but not 2 itself). Then, find the next number (n, say) that is not crossed out and cross out all multiples of n (but not including n).
Repeat this last step provided that n has not exceeded 50 (the square root of 2500). The numbers remaining in the list (except 1) are prime. Write a program which uses this method to print all primes from 1 to 2500. Store your output in a file called primes.out.

I need my Java program (I'm working in Eclipse if it matters) to detect if an image is a portrait or a landscape, but since i am directly downloading them from my camera they only have it written somewhere in metadata, the image width and height is the same for landscape and portrait. I have the rotation code and the rest of the program working, but I need to somehow get a variable (for example integer one) to tell me if it is a portrait or a landscape image. I tried getting to the metadata but my Eclipse decided that import com.drew.metadata.Metadata; cannot be resolved.
BufferedImage image = ImageIO.read(new File(imagePath, imageName)); and after I get the variable "orientation" it looks like this
int orientation = ???;
BufferedImage newImage = oldImage;
if (orientation>1){
newImage = rotate(oldImage);
}
I wanted to make a small program to move a small rectangle by pressing the WASD keys. The program works, except that when I hold a key to move the rectangle, after a second, auto-repeat starts up, and the rectangle motion accelerates. I want to prevent automatic repeat to activate, so that the rectangle moves at a constant speed when I hold a key and stops when I released. Here is the ButtonMotion classe :
import java.awt.event.ActionEvent;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.JButton;

I'm learning about abstract classes and I have to create an abstract auto class with make and price of a car, then two classes with a different type of car, and finally a main to use them. Everything seems to work and when I run it it's fine but I do get an error on the main that I'm not using the local variable buick1 and acura1.I'm curious because, while it runs for me, I want to make sure I'm doing it right and don't know of another way to do the output than this. I've put all four classes but the issue is on the last one (5 and 7).
public abstract class Auto
{
protected String makeCar;
protected double priceCar;

I'm doing an application which needs a JTable with data from an existing database. I need the table to periodically (I plan to use a Timer) reflect the changes made to the DB (inserting new rows, deleting or updating existing rows) without making the dirty approach of clearing the whole JTable and refilling it again, which is not nice. I need to just add/modify/delete the needed rows, not the whole table.

There is also an operation for checking to see if the dictionary is empty.
