How do you read in different kinds of data?

Hi
How do you read in integers first and next read in a string of characters?
Please help.
Thanks,
Sincerely,
Egan

You don't give enough information to provide a definitive reply. DataInputStream is Java's IO class that is designed to do that . This reference has example code of how it's used.

How would you read in each line of data and display them to message box?

How would you read in each line of data from the _.txt file_ and display the whole data using an information-type message box?
I know how to display each line of the .txt file data, but I do not know how to display the whole thing.
Here is how I did to display each line of data using the message box:
import javax.swing.JOptionPane;          // Needed for the JOptionPane class
import java.io.*;                         // Needed for file classes
public class problem3
     public static void main(String[] args) throws IOException
          String filename;          // Needed to read the file
          String categories;          // Needed to read the categories
          // Get the filename.
          filename = JOptionPane.showInputDialog("Enter the filname.");
          // Open the file.
          FileReader freader = new FileReader(filename);
          BufferedReader inputFile = new BufferedReader(freader);
          // Read the categories from the file.
          categories = inputFile.readLine();
          // If a category was read, display it and
          // read the remainig categories.
          while(categories != null)
               // Display the last category read.
               JOptionPane.showMessageDialog(categories);
               // Read the next category.
               categories = inputFile.readLine();
          // Close the file.
          inputFile.close();
}I think I need to change here:
// If a category was read, display it and
          // read the remainig categories.
          while(categories != null)
               // Display the last category read.
               JOptionPane.showMessageDialog(categories);
               // Read the next category.
               categories = inputFile.readLine();
          }but I don't know how to.
Could you please help me?
Thank you.

What is not understood about your question is which part of "read a bunch of lines and display them in a textbox" do you not understand.
First thing's first though: You do recognize that "read a bunch of lines and display them in a textbox" has a few distinct and completely independent parts, right?I'm sorry. I'm not good at English, so I do not understand what you said...
What I was trying to say is "How to display the whole lines of .txt file in single dialog box."We know that.
Do you understand that any problem can be broken down into smaller pieces?
Do you understand that your problem has the following pieces?
1. Read lines from the file.
2. Put the lines together into one String.
3. Put the String into the message box.
and maybe
4. Make sure the message box contents are split into lines exactly as the file was.
(You didn't make it clear if that last one is a requirement.)
Do you understand that 1-4 are completely independent problems and can be solved separately from each other?
Do you understand that you have stated that you already know how to do 1 and 3?
Therefore, you are NOT asking "How to display the whole lines of .txt file in single dialog box." Rather, you ARE asking either #2 or #4 or both.
If you say once more "display all the lines of the file in one dialog box," then it is clear that we are unable to communicate with you and we cannot help you.

How do you combine 3 different itunes libraries from 3 different computers to one computer?

Can you keep it from creating duplicates? These libraries have some duplicates.

THANKS for any suggestions.

You can't.
If accounts could be merged, then everybody could merge their accounts with everybody and there would be no need for anyone to buy anything.

How do you read your favorite feeds?

Hi! This is my very first post on Arch forums.
I'm wondering about how do you read your favorite feeds? Which software do you use and why (what kind of features).
I'm more interested in finding a little software that uses the system tray.
Yet I'm also curious about just how does, those who utilize RSS, do it.
Personally I've used YARSSR, which is exactly what I want, except for few problems..
On Ubuntu it used to be as easy as make, make install (having build-essenial installed). On Debian 4.0 stable it is in the stable repos, so it was even easier. On Arch it's not in any of the repos nor AUR and make, make install didn't work:
# yarssr
bash: yarssr: command not found
# /usr/local/bin/yarssr
Can't locate Gnome2.pm in @INC (@INC contains: /usr/local/lib/yarssr /usr/lib/perl5/5.8.8/i686-linux-thread-multi /usr/lib/perl5/5.8.8 /usr/lib/perl5/site_perl/5.8.8/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl/5.8.7/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl/5.8.6/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.6 /usr/lib/perl5/site_perl/5.8.5/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl/5.8.4/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.4 /usr/lib/perl5/site_perl/5.8.3/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.3 /usr/lib/perl5/site_perl/5.8.2/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.2 /usr/lib/perl5/site_perl/5.8.1/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.1 /usr/lib/perl5/site_perl/5.8.0/i686-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl .) at /usr/local/lib/yarssr/Yarssr.pm line 3.
BEGIN failed--compilation aborted at /usr/local/lib/yarssr/Yarssr.pm line 3.
Compilation failed in require at /usr/local/bin/yarssr line 13.
BEGIN failed--compilation aborted at /usr/local/bin/yarssr line 13.
I'd love to understand what's going on. How to install it right.
Anyhow, it's far from perfect anyway. It's the single thing that is not working so perfectly on my Debian as it should. Uses way too much CPU, sometimes stays trying to update and never does update nor allow forced updates, no quitting, etc..
I also use Google Reader, which is great to read many feeds and manage them, etc.
All I want is a little applet (maybe GNOME applet?) that gives me quick glimpse of my top favorite feeds, without using my browser nor launching a full-functional aggregator.

Hi James.
I'd like to know how you want to read your news
i'd prefer a cli frontend, web front would be bonus (river of news style).
snownews is good, just needs a few tweaks, some ui ones, and the main one being:
often i dont get to read news for a few days straight, so i'd like something i can put in cron and it'll update, and log the news for a few days straight, so when i get back it's all there. this generally limits me to one of the web clients, i dont know any desktop apps that do this.
i might write up an app to do this someday
as for your yassr problem, pacman -S gnome-perl?

How can you check a different iCloud account in safari in an iPad?

How can you check a different iCloud account in safari in an iPad?

As currently designed, you cannot. Once iCloud detects you are on mobile Safari, it switches you to the iPad screen.
If you had another browser that would allow you to pretend you were a desktop Safari client, ie8 or 9, or Firefox, that might work.
But, Puffin and Opera mini don't work.

How do you read an iTunes Book on your Mac computer?

When my iPod was down, I wanted to reply to a friend about something I had read on a book that I had purchased on the ITunes Store. Clicking on the book in iTunes on my iMac would not open the book so that I could read it. I copied it to my desktop, but when I tried to read it with Text or Pages, it would not give me anything but jibberish. I asked the above question (title) on the iTunes Store Search bar, but it only gave me an App that was a Chinese book reader. So, How do you read an iTunes Book on your computer?

How do you read the camera position in the 3d picture control?

Hello,
There is a method to setup the camera position, but how do you read the current camera position? e.g. the user uses the mouse, ctrl, and shift, to change the camera position. How do you read this new camera position? There don't seem to be any properties to do this.
I've read this thread:
http://forums.ni.com/ni/board/message?board.id=170&message.id=214629&requireLogin=False
but the question was never answered....
From the comments in that thread, even if you had the proper documentation for the "Model Matrix" property, you couldn't get the information necessary to calculation the camera position.

Lorielle,
Thanks for the VI.
Could you point me towards a more detailed description of the "Modelview Matrix" property? I've attached a screenshot from the online help. It is not very helpful.

How do you add a custom label to dates in contacts.....

How do you add a custom label to dates in contacts- I have multiple birthdays in contact group and want to change label through customise to add additional birthday- unless another way to add second birthday to contacts and identify each one?????? or way to link contacts with same address phone number etc but id birthdays?????

You have some contacts with more than one birthday?
To add a custom label for a date, select Edit for an existing contact. Select Add Field. Select Date. Scroll up with the Info window above the date selection and select Other for the new date selection. Select Add Custom Label and then select this label for the new date field for the contact.
As far as linking dates with multiple contacts, the answer is no to that.

How do you create a column of sequenced dates in Numbers

How do you create a column of sequenced dates in Numbers without typing in each date? For example: 01/05/15, 01/12/15, 01/19/15, 01/26/15, 02/02/15, etc.

Hi Cha Ling,
Another way,
Enter your first two dates that show the desired interval- i.e. 01/05/15 and 01/12/15.
Select both cells and choose fill from the contextual menu.
Drag down to fill your column.

How do you merge two different users on one computer?

I created a user account on my computer, then when I used Migration Assistant to transfer some of the files off my old computer onto my new MacBook Air it transferred them into a new user account. How do I merge the two different users? They are both me.

You can't "merge" users, you have to transfer the files using intermediate steps to deal with Permissions issues.
You found out first hand that you should use Setup Assistant, rather than Migration Assistant to perform the action that is now causing trouble, and time.
1) Log in to the A account.
2) Locate all the files you want to move. Move them to /Users/A/Public. Note: Don't move any System-created top-level folders, like Documents, Pictures, Music, Movies, etc. Just move their contents.
3) Log in to the B account.
4) Navigate with Finder to /Users/A/Public. Drag the files to the Desktop. This will make new copies of them that will have the correct permissions for User B.
5) Put the new copies of the files away in the appropriate places in B's home folder.
6) Delete the A user account if it is no longer needed.
Doing it this way will ensure that there are no permissions headaches with the files after they are moved.
Also, make sure that you BACK UP all of your data before starting.

How can you have multiple, different css link styles?

Every time I want to create a different looking link just for some copy, it always reverts to the A:link style, even if I create a new style that looks just the way I want. How can I create multiple link styles and then be able to select the one I want at any time???
I would greatly appreciate any help.
Allan

How are you applying the different styles to your links? In most cases, it's easiest to wrap the link(s) in an element, like a < div > that has a class or ID assigned, for instance class="altLinks". Then, set up the CSS style names like:
.altLinks a:link
...and so on. Then, the styles would just apply to links within the element(s) with class "altLinks". Here's a tutorial that might also help:

Otherwise, if you're still having trouble, post back with a link to your page so we can see what's going on.
