Unable To Run A Program To Extract News From News Channel Websites?
Sep 2, 2013
This is my code, I copied it from [URL]. I am trying to use it to extract news from news channel websites.
I used the following URLs:
[URL]
//------------------------------------------------------------//
// JavaGetUrl.java: //
//------------------------------------------------------------//
// A Java program that demonstrates a procedure that can be //
// used to download the contents of a specified URL. //
//------------------------------------------------------------//
[Code]....
Also, when I try a local server URL, the output screen goes blank, which I guess is due to lack of Text on the local URL. So, the little research that I did, made me believe that the code not running on external server was due to firewall on the server side. How to run it. Also : I work on a proxy network.( if that has something to do with this).

I'm planning to make a unique news app for android (maybe iOS later) and I am fairly experienced in Java. Im thinking to most likely use RSS feeds, but am unaware how to implement them into JAVA.

Is it possible to use Java to input data to website, and then get the output? For example, can you use java to input a word to dictionary.com and then get the data from the resulting webpage? I've noticed there are sometimes android applications where users of a website create an app version of the website, so presumably they are working on a similar principal of using java (for android applications) to inputting information (such as when you log into the website through the app) etc. and getting the same output information you would get if you inputted that information into the actual website itself.
The real problem is:
I'm not sure if I'm correct in assuming that this is all just java doing this or if there is some other programming language being implemented to achieve this resultI don't know what terminology I should be using, as I'm not getting any results when I search on the web for how to do this.

I am attempting to make a twitchplays bot but, I cannot get the bot to join my channel.
public class main {
public static void main(String[] args) throws Exception {
Twitchbot bot = new Twitchbot();
bot.setVerbose(true);
bot.connect("irc.twitch.tv", "6667", "oauth:734gln7txe9u0546a0fmdlkw95hcr9");
bot.joinChannel("#donnie64");
while(true) {
//this code will be looped
}
}
}
This is my main code, without the loop it gets terminated automatically. The console is blank after running the program.

I am developing a java swing application. In which i want to set a different text to a label in same program ( in single JFrame). I dont want to use another JFrame instead i want to use setText method of java and set different text to a label at different intervals of time according to my need.
I am using java 1.7 sdk and pupy linux as OS. Below i am giving source code.
What i am doing is in constructor of class i am setting an image to JFrame and setting text "Welcom...". And when user clicks on this JFrame a method is called which will clear the text "Welcome.." and sets new text to another label "Enter...." and from there another method is called and it clears label "Enter..." and sets a text "Plzz wait..". and yet there are more methods, i havnt provided here.
But what is happening is it shows welcome text and then directly Plzz wait..
Its not showing text Enter... because control is finished after last method gets executed.
My concern is i want to show all the setText (my messages) in a sequence. Without using another JFrame. There is no any user input other than user will click on first welcome page.
public class BackgroundFrame extends javax.swing.JFrame {
JLabel setTitle1;
JLabel setTitle2;
JLabel setTitle3;
JLabel setTitle4;

This program reads off of a text file that I have attached to my post. It is supposed to:
display the total sales for each week
the average daily sales for each week
the total sales for all of the weeks
the average weekly sales
the week number that had the highest amount of sales
the week number that had the lowest amount of sales
I can get everything but the very last one. In my code you will see that I tried to use a really large number so it would pull out the lowest amount, but it still didn't work: low = 100000000;
SalesData.txt (173bytes)
Number of downloads: 29

I am trying to create a program for class the uses two dimensional arrays. I am stuck on the second step that states Use two parallel arrays. One is a two-dimensional array -- a row of this array will hold six values in this order: [0] number of hours worked, [1] hourly pay rate, [2] gross pay, [3] net pay, [4] federal withholding, and [5] state withholding.
This is what I have so far:
Java Code:
double [][] data = new double [30][6];
String [] names = new String [30];
String str = null;
String detail = null;
int n = input(data, names, inputFile); mh_sh_highlight_all('java');
(there's more but i don't believe it pertains to this question)
My question is how would I create this array. Or, is that right above? I've searched online and in my book and I just don't understand.

I'm trying to print out the results of a program that calculates the number of seats the parties will get in an election.I have to print the partial results and the national results.
I can print te number of seats per party in each constituency, but how can i sum all seats per party in each constituency and print the national results?I'm working with vectors, which I know it might not be the best option, but everything is working, except the fact that I can't loop throuhg the vector and retrieve the total sum per party.Like, adding the seats for labour party in Constituency A and B and C, etc, and print the sum. And do the same for conservative party.Is it possible, or doIhave to create a method in Parties class to solve the problem?
This is what I have now.
for (Parties p : h.geral) {
show += String.format("Constituency - %5s - %5s - %d%n",
p.getConstituency(), p.getParty(), p.getNum_seats());
}

I'm trying to make my first servlet, however since I have only installed the Java SE, the javac compiler is complaining about missing packages (javax.servlet.http...)
I've realized now that I need javax.servlet jar or class files from Java EE, but after downloading java_ee_sdk-7u1.zip from Oracle here I'm not seeing any .sh or java_ee_sdk-7-jdk7-macosx-x64.sh installer (which I saw mentioned elsewhere). The oracle page only instructs to unzip the downloaded file, and searching for javax.servlet only reveals a few files which I'm not sure what to do with:
javax.servlet-api.jar,
javax.servlet.jsp.jar,
javax.servlet.jsp-api.jar,
javax.servlet.jsp.jstl.jar,
javax.servlet.jsp.jstl-api.jar,
javax.servlet.ServletContainerInitializer,
How do I go about installing the Java EE libraries I need? I am on a mac, and I'd like to do this without IDE, using the command prompt if necessary.

I'm looking to get two values from this string. I have tried re formatting and with little success. I read this in from a text file and then tried the below code to extract it. I have also tried
{Deposit=100.00, Fees Paid=5.00}
I am just looking to get the 100.00 and the 5.00. I tried using this code below but it separated it into Comma and put it in an array which is probably what im not looking for.
[code]
final Pattern pattern = Pattern.compile("[=st]");
final String[] result = pattern.split(st2);
System.out.println(Arrays.toString(result))
[code]

I am supposed to read in a file and extract the data. I am trying to add a Long into an Array that I initialized. So this is how my method looks like :
Java Code:
public void readOSMWay(File osm){
try {
Scanner output = new Scanner(osm);
while(output.hasNext()){
String line = output.nextLine().replace("^s+","");
if(line.startsWith(" <way")){
Road way = new Road(line,true);
[Code]...
I am having problem with the else if block. I am supposed to add all the Long values into the array.
error: Java Code: The method add(Long) in the type ArrayList<Long> is not applicable for the arguments (String) mh_sh_highlight_all('java');

What I am trying to do is extract the digits from between the words 'deal' and 'of'. I was wondering if this was possible to do with a regular expression or if I should just use a scanner.
UNIQUE Passive - Cleave: Basic attacks deal 20% to 60% of total Attack Damage as bonus physical damage to enemies near the target on hit (enemies closest to the target take the most damage).
Is there a regular expression that I could use in order to extract the '20' and the '60' from the above text. Below is what I have tried, but does not work.
(?<=deals)(d+(?=%))(?=of)
just to make a clarification, these numbers will not be the only numbers and the strings themselves will change. Everything can be considered a variable. The only constants between each string would be the words 'deal' and 'of'. The regex pattern "d+" is not a viable expression for my case

consider this statement from a jsp file(there are many more statements like this in jsp file..) Statement -
<h:dataGrid something styleclass="styleclass1" something1
onClick="event" something2
<% this is a scriplet tag %>
something3
style="style1">
<h:output text>hello i am text</h:output text>
</h:dataGrid>
What I want is to extract(and store it somewhere) the part from "<" to ">" where:
< - is the one in "<h:dataGrid"
> - is the one in "style1>" and not the('>') one that appears in the end
of "</h:dataGrid>" or "<h:output text>" or "</h:output text>"
Problem is the text b/w && is in multi-line...&& there are scriplet tags in between them.. so i don't know how to extract this particular string.. i tried using using some regular expressions but couldn't find the exact one..
(this was just an example && instead of this "" tag it can be anything like again in this line :
<h:output text>hello i am text</h:output text>
I want to extract the string from "<" till ">" where :
< - is the one in starting of "<h:output text>"
> - is the one in ending of "<h:output text>" and not the one in "</h:output text>"
However the difference b/w this example and the above mentioned one is that this one is not multi-line and doesn't contains any scriptlet tags)....

I will be developing a change and would like to know how can i parse a mail header in OBPM using java.
I want to get the message id, date and time the email recieved and email size.
Our code is already fetching the attachment of the email using the following syntax.
mailAttachments = mail.attachments;
I tried creating a variable like mailHeaders = mail.headers, would you know how can i get the details i want by parsing the variable? so far I wasn't able to check what mail.headers return as i'm currently having issues running our code locally due to DB connections.

I need to break it and #numbers in braces are assigned to string array and they should cal by one by one. similarly next level on calling #166 same operation should perform
{#166=ADVANCED_FACE(",(#165),#129,.F.);}

I do have a quick question about string manipulation. You see I've been given a simple exercise that involves asking the user to input a number between 1,000 and 999,999 and displaying the result. Simple enough, but the caveat is that if the user keys in the comma, say 24,000 instead of 24000 for example, the program is not to display the comma. I don't see how to do this without an 'if' statement. The book says the 'if' is not necessary but does offer this hint: "Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract the substrings consisting of the first n-4 characters and the last three characters."
What good is n-4 going to do if the string's lengths varies?
Here's what I have written thus far:
import java.util.Scanner;
public class P13
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Please enter a number between 1,000 and 999,999: ");
[Code] .....
