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---*
3 *--*
4*-----*
I want to get it to look like
0*------*
1 *--*
2----*
3 *---*
4*------ *
( I replaced spaces with -) So far I have
System.out.println("Input a size(must be larger than 1: )");
size=input.nextInt();

I am just trying to move a rectangle in a diagonal line. When the applet pops up, the rectangle is there but doesn't move. If I drag the sides of the applet to make it bigger or smaller the rectangle will redraw itself and move, but I want it to move without touching the window.

package javaapplication3;

The area of a square is stored in a double variable named area . Write an expression whose value is length of the diagonal of the square. Do I use math.sqrt?
View Replies View RelatedCoding (must follow pseudocode algorithm provided) for comparing characters of a word to a puzzle board char[][].
I've gotten the horizontal and vertical searches to work, but I'm having a difficult time figuring out how to search diagonally.
Here's the search algorithm format I have to use:
for each guess word
for each letter of the puzzle
for each letter of the guess word
check for diagonal match
if found, add word to list, break to next guess
I'm assuming there should be a +1 horizontal offset after I find the first letter, but every index I've bumped has caused me to screw up my array bounds. I'm missing something.
Here's the algorithm I'm using for diagonal search. This same algorithm worked for vertical search (minus the offset of course)
//diagonal search
for(String word : guessWords) {//for each guess word
int letterCount = 0;
int index = 0;
for(int j=0; j<grid[index].length; j++) {//for each puzzle letter

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?");
}
}
}
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

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'm new to Web Services and I've been finding trouble when creating my first one. Before talking about the problem, I'd like to show you the process I followed to see if it's ok. Note that I'm using Eclipse Kepler, Tomcat 5.5 and Axis2.
1- I created a new Dynamic Web Project.
2- I created the Java class that implements the service with just one method, a simple one: you pass it a name and it returns "Hi, <name>"
3- Right click over that class and then: Web Services -> Create Web Service
4- I go through the next steps. On the last one, I select "Launch the Web Services Explorer to publish this Web service to a UDDI Registry". Click on "Finish".
5- The Web Services Explorer is launched, but I just get a "HTTP ERROR: 500" message.
I understand that my Web Service wasn't published and therefore it's useless to create a client as it wouldn't connect.
I need to create a chart for work and comes across this sample from mbostock's chord diagram (bl.ocks.org/mbostock/4062006).
I only need to revise the tick label (names, display positions) but I don't know how to do it as I have 0 experience with Java.
My sample data for the var matrix is
[0,100,100,100]
[0,0,99,98]
[0,0,92,84]
[0,99,0,0]
which shows flows between country A, B, C and D.
I would like to revise the tick labels, so that:
1) Instead of showing 0K 5K 10K, I would like to show the country names (A - D), with no number or tick. I figured out this one by just commenting out all the codes relating to ticks.
2) Place the country names in the center of the arch. I don't know how to do this one.

The problem is that it's not out putting all of the information that I need it to. Here's my code:
Here is the class that prints the first char, second char, etc.:

View Replies View RelatedI'm trying to create complex Character objects. Each object has a name, and for each object with the same name, they share some of the same initial data. However, there are also some bits of data that are given to the object when it's created. For example, an "Elephant" always starts out having a weight of 500, but its position is determined when it's created. Any of these values may later be changed during runtime.
class CharacterStaticParameters {
int weight;
int numberOfFeet;
int numberOfEyes;
