I have problem how to store the array?
for(i=0;i<empRec.length;i++)
if(empRec.getCategory()=='F'||empRec[i].getCategory()=='H')
if(empRec[i].getCategory()=='F')
Movie interesting[]=new Movie[2];
interesting[i].setCategory('F');
System.out.println("Category:"+interesting[i].getCategory());
has a exception like this Exception in thread "main" java.lang.NullPointerException
at Movie_video.main(Movie_video.java:146)
this is my part of the coding... i want ask how to Separate out the movie numbers of all the movies in the Fiction and Horror categories and store them in an array ?interesting?.

It seems the problem is situated in the line +interesting.setCategory('F');+
You instantiated the array, but not the object within the array. A possible solution could be:
for(i=0;i<empRec.length;i++)
if(empRec.getCategory()=='F'||empRec[i].getCategory()=='H')
if(empRec=new Movie[2];
interesting[i] = new Movie();
interesting[i].setCategory('F');
System.out.println("Category:"+interesting[i].getCategory());
}But very unusual to add only one object to an array of 2. What are you aiming for using the array +interesting+?

Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported.

Hi
I am doing my M.Tech Thesis in Image reconstruction and I am using labview for simulation and I want to know how to store the output of a analog to digital converter into an 2D labview array.nitinkajay wrote:

How exactly are you performing 'Analog to Digital'???
Grabbing image using camera OR performing data acquisition using DAQ card OR some other way????
I am not allergic to Kudos, in fact I love Kudos.

Suddenly I have problems moving files to the trash... get a dialog saying Finder wants to make changes and I must provide the password... Any explanation or ideas how I can get this to stop?
Please take these steps if you're prompted for a password when moving items in your home folder to the Trash.
1. Triple-click anywhere in the line below on this page to select it:
~/.Trash
2. Right-click or control-click the highlighted line and select
Services ▹ Show Info
from the contextual menu.* An Info dialog should open.
3. The dialog should show "You can read and write" in the Sharing & Permissions section. If that's not what it shows, click the padlock icon in the lower right corner of the window and enter your password when prompted. Use the plus- and minus-sign buttons to give yourself Read & Write access and "everyone" No Access. Delete any other entries in the access list.
4. In the General section, uncheck the box marked Locked if it's checked.
5. From the action menu (gear icon) at the bottom of the dialog, select Apply to enclosed items and confirm.
6. Close the Info window and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above. -
what is an smpt password? I have problems sending photos using the stamp at the bottom because it asks for some smpt password and I have no clue to find out what it is, how to set one of find one if I somehow put one in and don't know what it it.
It's the password for your outgoing mail in your Mail account. You need to set it up in your Preferences.

i have problem in mac store when i try to download app i get note (( app failed to download use the purchases page to try again ))
i try to downlod twitter and ccleaner but i can't open the app ?!?!!!It can also be an iTunes issue. Many of us, including myself, are not used to the new interface of iTunes 11 and would find ways to downgrade the available iTunes 11 back to iTunes 10.7 in Mac OS Mavericks. The only issue with downgrading (using AppZapper and Pacifist) is that you will not be able to update/install apps from the App Store after rebooting the Mac.
If you happen to have downgraded your iTunes in this method, then uninstall the iTunes 10.7 and reinstall iTunes 11 again - the App Store should resume its download/update function without any issue.
Hope this helps. -

Chat App: how to store the user IP in database when they login.
hello,
i am working on chat application. first i made a login GUI form. after login when we run the Chat program, it ask the ip address of the server to whom it want to connect. and if u enter the ip address, it will connect to the server and chat will begin, thats working perfect.
but i want to show the list of users who r logged on and when i simply click on the user name, chat should begin.
i have the logic that when any user log in, then its IP address will be stored in the database. this ip address will shown to the online users.
but i dont know how to store the user information in database when they log in. can any body suggest me wht lines of code i should use.
thanks.palakk wrote:
i have the logic that when any user log in, then its IP address will be stored in the database. Bad approach. That will only work if this chat is only intended for use on a LAN. If it's used on the internet, then your users' IP addresses will almost always be either a) those of their routers, or b) private IP addresses, and in both cases, multiple users can have the same IP address.
this ip address will shown to the online users. Why would you want to do that? I want to chat with "Bill", not with "1.2.3.4".
but i dont know how to store the user information in database when they log in.Do the same thing that you're currently doing to store the IP address, but with the other information you want to store.
can any body suggest me wht lines of code i should use. This is not a code writing service. -
How to store the datas in a .txt file in to a JTable in Java Swing

Here i want to know how to store the data's of a .txt file
in to a JTable in java swing.

in a JTable.This is what i want.So pls. do help and provide the code as well.I will be thankful.Since i am involved in a project which involves this it is Urgent.
Thanx,
m.ananthuYou can't just display data from a text file in a JTable. You have you understand the structure of the data so that you can parse the data and create a table model that can access the data in a row/column format. Here is an example of a simple program that does this:

How to store the images in Oracle?
Hi,
I am a new developer, trying to find out how to store the images in Oracle. Is there anyway that I can store the images in Oracle and insert them into my html file?
Thanks!
SarahThere is a simple image example available from OTN.
From the OTN main page, go to Products --> interMedia --> Sample Code. The name of the example is "Load rich media content with a browser."
This example loads and retrieves an image from an Oracle8i database through a web page using the Oracle interMedia Web Agent.
