Java help needed(PLEASE)

I have a Question for all you gifted people:
I am designing a sort of quiz which takes questions and three possible answers from a database(which also holds the real answer).It prints these on the dos screen and I then have a System.in statement which allows the user to enter his or her answer (eg A,B,C or 1,2,3). I need a way of adding up the score at the end!!I was thinking of storing there answers in an array and compairing there answer to my correct answer in the database and if it is the same add 1 and if it not the same add 0???
How would i write the System.in answers into an array and add them up???
These are my thoughts on how to do this i would love to hear yours!! And also a help with writing the code for the above system of scoreing would be GREATLY appriciated!!
thanks everyone,
james.

As mathuoa pointed out, since you already display the 3 possible answers to the user, get them into an array and display them on the screen. Then, as the user enters an answer, compare them with the three answers and if it is correct, update the score variable as such. If you want the history of answers that the user has given, then u will have to use a Vector/List/some such collection object to hold the user's answers.
java.util.Vector answers = new java.util.Vector();
answers.add(usersAnswer1);
answers.add(usersAnswer2);
Then, to get the entries,
for(Enumeration e = answers.elements(); e.hasMoreElements();)
System.out.println(e.nextElement());
//Do something with the answer.
This is one possible way of getting the answers from the user!

Help needed please, with Iphone stuck with apple picture and progress bar after software update attempted

Help needed please, everytime I try to update the software version on my iphone it comes up with a message saying it could not be completed and is now frozen with the apple picture and progress bar on it. Do I unplug it and hope the macbook pro sees it again, I also stupidly did not back up before starting the download which I realise I will have to go back to the previous back up. This keeps happening, everytime I do this type of update, I'm starting to think I should just give up on updating my software on the Iphone. I thought it was happening because I was using a window based computer to do the updates, this time I used my Macbook Pro. Please somebody help

Have you guys been able to activate your iphone yet? I bought an iphone 4s from eBay and it worked fine, but the previous user had left some data on it, so last night I used the "erased all content and settings" to restore it to factory setting so I can start fresh and restore my backup. But now I'm stuck at the activation screen (I get the same "the activation server is temporarily unavailable") and can't get it to activate, even if I use my old deactivated AT&T sim card (I'm on straighttalk now).
I might try activating it with an active AT&T sim card from my fiancee's phone when she gets home, so I'll let you know how that works outs.
If it's true that the server is down; anyone know when it will be back up again? Thanks in advance.

Hi everyone
Programming help needed here. Any advice would be greatly appreciated!!!
I have been assigned some work for a program called Processing 1.0 availale at http://processing.org/download
I was give the 9 individual programs I needed to make however they were converted to Java files from .pde files. The program is based on Java but only runs .pde files and NOTHING else!
I decompiled the files and got the source code, but it is a slight variation of the original someone made in processing, and needs some tidying to get it to run.
I think the programs are very simple for a programmer, although I AM NOT.

HELP NEEDED PLEASEShouting is a good way ensure you don't get help. Also you should give a meaningful subject.
Any advice would be greatly appreciated!!!I suggest you ask a question after providing enough information to be able to answer it.
Also use CODE tags when posting code as it make the code more readable.

New Hard drive, can't access certain aspects. Help needed please

Hi everyone.
I have an HP Pavilion dv6-6052ea laptop.
I've been having problems with the hard drive so got a new one installed.
My main issues are since getting it back, I can't access any of the original HP installations etc (I've downloaded all the drivers I know about through HP).
The 2 main things I'm missing are 2 things that came with the laptop.
1: Beats Audio sound system
2: Video Graphics: AMD Radeon HD 6490M (1 GB DDR5)
and I have no idea how to get them back. Can anyone help. Do I need to install specific drivers? I can't find any trace that they exist on my laptop now apart from the stickers on the laptop! Any help is greatly appreciated.
I never had any CD back ups for the laptop. I do have the old HP back up etc saved on a USB but I don't know enough about the folders and files to know what I need to look for. (I still have the old hardrive.)
Again, any help is massively appreciated. Thank you!
Tony

If you used your HP Recovery Media, all factory install drivers and software would have been installed. If you didn't create your HP Recovery Media when you first setup your computer, please contact official HP support in your region / country, via the HP Worldwide Support Portal, to see if HP Recovery Media is available for your computer.
If a generic Windows 7 installation disc was used, you will need to install all HP specific driver for your computer. Please try IDT High-Definition (HD) Audio Driver, Intel High-Definition (HD) Graphics Driver, and AMD High-Definition Graphics Driver to resolve your missing drivers issues. Windows 7 64-bit driver for your computer can be found on the HP Pavilion dv6-6052ea Entertainment Notebook PC Drivers page.
If you have any further questions, please don't hesitate to ask.

MP3 burning help needed please

Hi,
I'm hoping someone can help me please.
I'm wanting to burn a mp3 cd but with the songs in separate folders so that when i play them in my car i can flick between the albums instead of having to go through all the singles one after another.
Does anyone know of a good mp3 burner that can do this, and where to get it from too.
All and any help in this matter is greatly appreciated
Cheers
Paul

You want them in separate Album folders?
Put the songs into the playlist.
Sort the playlist by Album then burn it as MP3* disc.
This will put the songs into Album folders.
Likewise, if you sort by Artist, songs will be put into Artist/Album/ folders.
* Note that only MP3 files will be burned to the disc. If the files are not already MP3 format, they will be skipped.
If you burn it as a DataCD, it wil work the same except it will copy the files regardless of format. I do this as my CD player will work with both AAC & MP3 formats.

the problem im having is whenever i make the choices 1,2,3,4 (CATEgorys) AND hit 1 or 2(current or new member selections) it brings up more than one category...
for example when i hit 1(Category full) and 1(current member)..it displays this:
Are you a Current Member (press 1) or a New Member (press 2): 1
CURRENT FULL MEMBERSHIP SELECTED
Current full membership fees yearly are 800
Full members must also pre-pay 150 on a card can be used in the club facilities such as bar and shop
The total of this membership is: 800
The total number of 'CURRENT FULL MEMBERSHIPS = 1
The total amount of income for 'FULL MEMBERSHIPS' within the club = 800
The total of this membership is: 175
The total number of 'UNDER 18 MEMBERSHIPS' within the club = 1
The total amount of income for 'UNDER 18 MEMBERSHIPS' within the club = 175
Please Press '0' to add another member or any other key to exit.:
under 18 membership as well?...does this for other selections too...is it my arithmetic operators?....my if loops?...

Importing XML into Java. Help needed Please!!!

Hi,
I have downloaded j2sdk1.4.1_05 and want to configure it to import XML files into a DOM in Java. I am having trouble doing this and need help. I read that version 1.4 support JAXP 1.1 but I am having trouble finding the JAXP-api.jar file. It says to put all the other Jar files into a folder and leave the JAXP-api.jar.
Could you please tell me how to set up Java so that I can import an XML file. I also downloaded JAXP 1.2. But there seems to be no installer.

*Basic* Java help needed...

I feel like a complete novice for posting this kinda stuff, but i figured somebody would take 5 minutes and help me out. My final in my programming class depends on 2 programs, one of which is giving me some actual trouble.
What I have to do is create a java applet that allows a user to input their weight, select a planet, and then have their weight converted to what their weight would be on the selected planet. However, if the ouput is higher than 60 pounds, I need a picture of the michelin man to appear and the theme from star wars to play. If it is below 60, A multicolored asterisk should be displayed with applause.
I will post what code I have already made. Please note: ITS VERY VERY BASIC. I may have overcomplicated some things, and there is always more than one way to do something (in my experience). Also, I kinda just converted a temperature conversion applet, so there may be some extra stuff I don't need.
Please help.

I am guessing that you are wondering where to go from here. If so http://java.sun.com/products/plugin/1.5.0/demos/applets/Animator/Animator.java may prove helpful.
Also I would recommend using arrays of planet names and weight multipliers. It could make your code a lot less cumbersome.

Urgent help needed, please help me

Hi,
I am developing a web site using Java Servlets. The site requires to send XML as POST to an HTTPS server and get the response.
Development environment:
Laptop running Windows XP with jdk1.3.1, j2sdkee1.3 and Tomcat 4.1.
Since I need to use https request from the servlet, I am using the following code;
URL url = new URL("https://www.somesite.com");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
To use the above code I downloaded the jsse1.0.3_03 package from the sun website and added the three jar files to the appropriate location. Also edited the java.security file.
The program compiles and when deployed to the web server, it works great.
Now the problem;
I need to deploy the web site in a server that is connected to the internet. This server is running Windows 2000 Server. It has the same jdk1.3.1, j2sdkee1.3 and Tomcat 4.1. Also I added the three jar files from jsse1.0.3_03. I also updated the classpath in the environment variable accordingly.
Everything is pretty much similar to the Laptop that I use to develop the site except that the OS is Windows 2000 Server.
But when I deployed the class files to the web server and tested the site, the servlet gave the following error:
"unknown protocol: https"
What could be wrong? I really need to fix this issue as soon as possible and any input from you will be highly appreciated.
Thanks in advance,
Rajesh
