You could give a sequence number(1-50) to each of the questions in you access db and then do something like this every time you select a question (Generate a question number)
Random rnd = new Random();
int questionnum = rnd.nextInt(50) + 1;

I was tasked to write a program asks the user for the name of a file. The program should display the contents of the file with each line preceded witha line number followed by a colon. The line numbering should start at 1.
I got to the point of displaying the content in the file but I am not sure how to code for the line numbers and colons. Any suggestions?
Here is what I have so far:
import java.util.Scanner; // Needed for the Scanner class
import java.io.*; // Needed for the File class
/**
This program reads data from a file.
*/
public class LineNumbers
{
public static void main(String[] args) throws IOException
{
// Create a Scanner object for keyboard input.
Scanner keyboard = new Scanner(System.in);
// Get the filename.
System.out.print("Enter the filename: ");
String filename = keyboard.nextLine();
// Open the file.
File file = new File(filename);
Scanner inputFile = new Scanner(file);
// Read lines from the file until no more are left.
while (inputFile.hasNext())
{
// Read the next name.
String familyName = inputFile.nextLine();
// Display the last name read.
System.out.println(familyName);
}
// Close the file.
inputFile.close();
}
}

You're a beginner therefore at some point recently you should have counted from 1 to 10 in a loop.
Fill in the blanks.
int lineNumber = 1;
while(....)
{
....
System.out.println(lineNumber + ": " + ....);
lineNumber++;
}
ps. Please put your code in <pre></pre> tags; as it makes it more readable. 
If at first you don't succeed, you're not Chuck Norris.

Here is what you should do
<br />
int lines = 1;<br />
while (inputFile.hasNext())<br />
{<br />
String familyName = inputFile.nextLine();<br />
<br />
System.out.println( lines + " " + familyName + ";" );<br />
lines++;<br />
}<br />

Gentleman:
I just added a Java window to an ASP web page which shows an enlarged graphic. This works perfectly in Explorer, however it does something unusual in Firefox. Firefox opens a user request interface which asks the following:
What should Firefox do with this file:
Open With ... etc
or
Save
Neither option will open the new graphic in the Java window as it does in Explorer. Following is the code that I am using to open call the Window and get the graphic:
IN THE HEADER
<%--Large WIndow Scripts --%>
<script type="text/javascript">
function OpenLargeWindow1(image)
{
window.open("Ads/" + image, "", " width=760,height=300,top=200,left=200,scrollbars=0").focus();
}
</script>
IN THE BODY
<a href="javascript:OpenLargeWindow1('gears33.png')">
<asp:Image ID="Image18" runat="server" ImageUrl="~/Ads/plus_sign.png" /></a>
Does Firefox require a proprietary code or what option in the select process will put the graphic in the window if any? OR ???.
Any insight to this dilemma is appreciated.
Thank You, Pat

This is not a Java question but a Javascript question and is more applicable to the Web Development forum.
I believe Firefox downloads some file types rather than showing them and the same can be said for Internet Explorer, pdf's and png's for example. I would suggest creating a page which takes a 'get' variable which would then display the image on the page. Eg. javascript:OpenLargeWindow1('showimage.aspx?img=gears33.png') to avoid browser inconsistencies.
If at first you don't succeed, you're not Chuck Norris.

Fly,
Thank you for your reply. Being a Java novice, I do not understand the exact context of this code, but in fact, I have created a new page using your suggestion and with the graphics properly located, I am able to get the desired results in both browsers. It's a little long winded and I do not know if it is the best way to do it, but it works and I thank you for your input. Accordingly, I have marked your answer as correct and appreciate your help.
Re: Forum -- I apologize if I am "in the wrong place", but that is what comes from not knowing about a particular subject. I assumed that Java and Javascript are alike enough that a Java programmer would have the answer, since there is no category for Javascript. No offense was intended and I will use the other forum for future questions in this area. In fact, since the application is (.aspx), I also posted this question to the other (.Net) people, of which I am one, thinking this might be a common problem, but no one there replied to it. I am new to "Internet Applications" and I dislike this programming very much (all my experience comes from programming business desktop applications in C#), but in the words of the immortal John Wayne, "A Mans Got To Do What A Mans Got To Do!". Thank you again for your help...Pat

How about a program that suggests topics for new programs based on some questions asked etc..
If you get one working you should post it here. I'm sure it could be quite useful...

Do you mean Java (JSP) or Javascript?
You can't in Javascript, unless you want to use ActiveX.

Can you explain what you mean by 'termination part' and generally be more specific about your problem.
On another note, can you please put your code in <pre></pre> tags so that the formatting is preserved and it would make it more readable.
Example:
public class Example
{
public static void main(String[] args)
{
System.out.println("Formatted code");
}
}
Do you see how much nicer that is to read.
If at first you don't succeed, you're not Chuck Norris.

Real nice of u to reply chuck norris, try running the code in netbeans -i also wrote it there-, i'm kind of an amatuer when it comes to programming. the terminating part i meant was, after the whole taking of the test, and the result comes out, its suppose to terminate the program but it doesnt... thanks

You have it in a for loop! And it is repeating itself 13 times.
