Efficient Way To Gather Data From Site Page
Oct 22, 2014
I'm looking for a way to gather data from a site page. all data is shown in the same page... I am trying to get the content and parse it is a bit crazy as data seems to be not organized. Itried to get it as a document but still looks crazy.
As all data is shown very clearly in the page (I would like every row to be an object) I'm sure there is some way to collect this data easily. (the data is from this page: [URL] ....)
I'll attach a snapshot and the content I got from the website.

Here is what I'm trying to do using arrays.
gather sales amount for the week
display the total of sales
display the average of sale
display the highest sale amount
display the lowest sale amount
using occurrences determine how many times the amount occurred for the week
make a sales main
make a sales data
This is what i have so far but I'm confused on how to start the occurrence and where it would be placed in order to get the information from the array
public class SalesData {
private double[] sales; // The sales data
/**
The constructor copies the elements in an array to the sales array.
@param s The array to copy.
*/
public SalesData(double[] s) {
[Code] .....

I am relatively new to JSF. I am trying to display data into a web page sorta like a jTextArea or at least onto a panel that is on the webpage, something similar to that. I can display the data in a particular format but it won't appear onto a panel in a specific location or the panel being a particular size.

I am currently working on a project where I have a dataTable, containing some of the information for a specific database table, with commandLinks at the side which I need to bring me to a new page(another jsf file that I have to display the relevant information there) and display only the row of data selected. I've been racking my brain about this and have been unable to figure out a way to do it.

I am new to JSP . I am Using Jdeveloper UDI to create JSP Pages.
My main idea in creating JSP to display data from one or more tables.
I created 2 pages called Serverpage.jsp and Messagecount.jsp and it is working fine as expected,
Now i want to create home page and it should also have left navigation menu and it should contain MessageCount and MessageStatus.
When i click on Messagecount or MessageStatus my home page should refresh and have to display new JSP page (MessageCount.jsp or Serverpage.jsp)
Here is my JSP pages
Serverpage.jsp
<%@ page contentType="text/html;charset=windows-1252" isELIgnored="true"%>
<!--<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>-->
<html>
<head>
<title>Welcome to Monitoring Page!</title>
<link type="text/css" rel="stylesheet" href="jdeveloper.css"/>
<script language="javascript" type="text/javascript" src="Calender.js">
[Code] ....

if one address point on another address. so set and get methods will be less efficient then an array, but add or remove will be more efficient by a linked list ? a linked list also inherit from queue so if i add an elemnt via "addFirst" function . where its adding the element ? to the right most or left most ?
if i have for example :
here [ ] --> [ ] --> [ ] --> [ ] -->[ ] or here
linked list its FIFO so the head will be the right most ?
Edit : its confused me a little bit but i understood now .so it will be at the left most. its actually ordered . not like the stack which is LIFO.

My GCD testing:
Java Code:
public static long gcd(long a, long b) {
if(b == 0) {
return a;
} else {
return gcd(b, a % b);
}
} mh_sh_highlight_all('java');
Is there a more efficient way? Also, what can I do to speed this forloop up?
Java Code:
for(long i = 1; i < 750000; i++) { dothis; } mh_sh_highlight_all('java');

I've a question on rounding doubles on 0.05 As far as i know there is no class method that is able to do this. To achieve this rounding i have the following code:
Example:
164.67 -> 164.70
173.33 -> 173.35
0.02 -> 0.05
double calculatedQuantity = 0.0;
// Formula to calculate the average working hours in a month
int totalWeeksInYear = 52;
int totalMonthsInYear = 12;
[Code].....

I am kind of new to Java. I have a query.. look at it. Have an xml like
<ProductList>
<Product Quality='Good' color='Blue'>
<Details ItemID='1001'/>
</Product>
...
..
</ProductList>
The <Product> tags can run into hundreds or thousands. Quality can have values like Good, Bad, Damaged. Color can also have various values (Blue, Red ..)
ItemID can repeat or can be different. So I want group by ItemID->Color->Good count or BadCount and TotalCount as below.
I want to get a sum like
<ProductList>
<ProductType ItemID="1001">
<Product_Detail CountGood="1" CountBad="2" CountTotal="3" Type="Blue"/>
</ProductType>
...
...
</ProductList>
I think using Hashmaps (Hashmap1 for ItemID, Hashmap2 for color, Hashmap3 for quality) may do the work. But I have to parse the xml number of ItemID's multiply-by number of colors multiply by various colors times for this.
Any better algorithm is there in performance perspective using Java.

This isn't solely related to java.awt.Color, it's more of a question on how to store methods or redirections to use methods on any value passed in. To explain my question I'll describe a scenario:
ClassA is an instanstiatable class
ClassA has an instance of ClassB called cB
ClassA has methods of affecting cB
ClassD is also an instanstiatable class
ClassD has an Array[x][y] of instances of ClassA
I want to create a ClassE which I would initiate it with references to ClassA's methods or their actual methods and then I can use ClassE to easily transform ClassD's instances of ClassA by the same methods.
What I'm actually doing:
I made a class called GameColor, it has methods like changeHue, setRed, setHue, changeBrightness, setSaturation etc, these methods affect an instance of java.awt.Color in the GameColor class instances, so like they can change the hue or set it with changeHue or setHue etc...
Now I want to do something like perform a single method on a whole BufferedImage, on each of it's pixels RGB. So, I'm thinking of creating a GameColorEffects class which I store references or actual methods of GameColor like changeHue, and then I use GameColorEffects somehow to change a whole BufferedImage more efficiently, what's the most efficient way I can store methods or their reference of GameColor and then later apply them on each pixel of a BufferedImage using GameColorEffects. So all I do is initiate GameColorEffects with methods or reference from GameColor, and then I can apply it to easily transform each pixel.

with arrays its binary search which finds a value in O(Logn) time but what about linked lists ? the most effiecient algorithm will be O(n) ? and i know that binary search cannot be implement on a linked list , therefore , the only way to search a linked list is a linear search ?

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.
