I am writing a java program which searchs data from a database on a website , my problem is that the url does not works on IE but works fine in other browsers..
private URL getURL(String selection) {
URL exampleURL = null;
String url = "http://www.example.com/list?keyphrase=";
if (selection.equals("mfcCode")) {
url += getURLcriteria(EditList.get(CurrentListIndex)

I am trying to make a program to go on a stock website find the value a particular stock is at and display it to the user. Then repeat at your selected timeframe.
I can get my code to read the entire source of the page or open a page but I cannot seem to get it to find something within the source.
What It would do when completed. Get input from the user on what stock and sight to search and how often to check it. Once the run button is clicked I would like it to take the input from the user and run in the back ground going on the website searching the stock and display the numbers back to the user. I have only been able to have it display the entire source code though, not just the stock numbers.

int dy = (int)(Math.random()*3) - 1;
if (x+dx >= 0 && x+dx<food.getWidth())
x += dx;
if (y+dy >= 0 && y+dy<food.getHeight())
y += dy;

I want to create an application wich can handle xml files ( display xml files's data on a html page) + insert those data into an oracle database.
I'm new to that, it a project for my internship. wich API is the most appropriate for that ( Jdom or Xstream or other), wich framework i can use ( there is only 3 IHM : connexion, upload file, display data, confirmation insertion data)?
I'm creating a web applicaion. for that i want to create a registration page. and this registration details have to be stored in the database.
I'm getting the below error while trying to send the data ...
The requested resource (/cmd/InsertRegtodb) is not available.
Here cmd is project name and InsertRegtodb is servlet name.
Actually the servlet is present is the mentioned address. but it is not connecting to it
There is one more servlet in the same folder and which is accessible from another jsp. But this servlet is not accessible even though i have used same code as it is used for the servlet which worked for me previously...
The question is when you send two messages from the client to the server does the server read the messages as one input or do you have to read both inputs on the server side?
Im using DataInputStream and DataOutputStream
On the client side I send two messages one for the database action to be performed and the send is the information needed to get the job done.
Example I want to search for a product in the database.
I send to the server an output message saying search product. I then send to the server which product I want to be searched.
The server then retrieves the message by in.readUTF(); switch statement determines what database action should be performed. Within that case I call another in.readUTF() to pass the information to the database on what product to search for.
Would this work or would the server read both messages from the client as one input stream?

I am currently concentrating on Java programming skills. Right now developing a Energy usecase in Java with Spring framework. Have business requirement to generate data along with outliers. For example, have two parameters called as min and max (centigrates). Generate a file between min and max and store in a file. Atleast need to generate 10 outliers in each 100 records. Outliers should be < min and > max. How to write a java class with this business condition. The file should be like,
Java Code:
Public class DataGeneration(int min, int max)
where min = 30
max = 50
UNIX_TIME_STAMP< >DEGREES
98938409384389384< >30
39083048938409384< >49
39583980398493840< >-30
90853948093849383< >100 mh_sh_highlight_all('java');
From above sample data file, it will be generating two outliers. How to create such kind of data generation in Java class?
I need to write a simple program that displays up to 5 pairings of data types (int, string) (string, long) ect. I need to have at least two classes, a Pair class (generic) and an PairTest class.
View Replies View RelatedI just trying to find the most efficient way to do this. I read in a csv file into a linked list and then I split the linked list into sections based on category for each element. Of course I used an array to split each element of the list. However I can do the sequential search by either ID and Name by using hashmap and making the key = name + ID and then doing key.contains(charSequence);. However I feel like this is inefficient and I would like to use the linked list instead of a hashmap which could be done by splitting the user input and used for method overloading by passing an int in one and a string in another. I feel like this approach is a little more redundant and maybe their is a better approach for searching for id and name. Below is an example of the elements in a linked list.
note: their are more elements than this.
element 1
name: George
address: 4410 something dr.
phone number: 978-888-6666
id: 43
element 2
name: Karla
address: 339 something dr.
phone number: 334-338-6556
id: 23
I have a blog hosting service (like Wordpress) written in PHP and MySQL, I'm gonna make Java Application for it (Runs on Windows, Linux and ...).
My Questions:
1. Can I use Connector/J to connect to my website database (MySQL)?
2. Which one is better? 1.Connect to website database, 2.Use Socket programming.
Is it possible to use java to log on to a website? I mean,Ii know how to connect to a website and send commands, but I am not sure how to tell the server that i want to login?
And then after you logged in is it possible to then do something? like, if you logged in to gmail.com you would be able to see your emails?
So I was just wondering if it's possible to create a program with JAVA that uses an algorithm to summarize data inputed. I've never done something like this before, If this is not possible with Java is it possible with C++ or any other language??

i am fairly new to java but have made a few projects so i do know most aspects that would allow me to complete the task its just i have been stuck at the same place now for 2 days.The project is to create a java program that can read specific data within a csv file to work out the averages etc. The csv file is a database of different weather stats . an example of the first 12 months of the csv file is below..
[CSV FILE]
year ,month,average rainfall etc

I know that once the data is indexed i can than use a double to find the average of the 12 specific pieces of data and so on. once this is complete i should than be able to transfer the data to a simple graph.

I have been given a task to scan the contents of a websites source code, and use delimiters to extract all hyperlinks from the site and display them. We havent been told anything about how to do this so after some looking around online this is what I have so far:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;

So my program can extract each line from the source code of a website and display it, but realistically I want it to extract each WORD as such from the source code rather than every line. I've looked around online but I don't really know how it's done because I keep getting errors when I use input.read();
How to make it extract each word from the source code?
I have a small application that I have been working on for several months. It works great. Now when I created an executable .jar file for it, it will not load data from a .csv file. I have tried looking into everything I can think if. I checked file paths, etc. I am using OpenCVS to read the csv. Is there an issue with that when you include it into another .jar file? I am trying to log if there is an error but I don't even get an error. I just doesn't run past that statement...
