So far, your code is reading in the data from the file.
Try adding some output lines to check what it's doing.
Follow the next step, getting the total value.
(BTW What's in the data file?)

I'm addressing the first error. I believe the diagnosis is correct (scope).
There are other errors, but we usually address them starting with the first.
Feel free to test the code yourself,...
The scanner is not visible in the for loop because of variable scope.
Try making the scanner static (belonging to the class).

Break the problem up and tackle and test each problem.
1. How do we generate a random number between 1 and 10,000?
2. Create an array to hold 10,000 numbers.
3. How do I store only unique...
How are you grabbing the last line of the log file? I presume the file is quite large, or may become so.
What have you tried so far? Any code to show us?
Most of the longer Java text books are available electronically. You can try them out on Amazon or look at a friend's copy and see if you like it.;-)
Java 7 allows a switch on a String, so you don't need to use a CharArray.
A few points:
Names of classes by convention start with a capital letter.
Try to use descriptive variables. 'wr',...
The error was java.util.NoSuchElementException
No line was found when using file.next()
Scanner (Java Platform SE 7 )
The while(file.hasNextLine()) loop will catch this situation, but I think...
The UML PDF doesn't open for me unless you actually download it.

Check your calculation. You need ticket_price x number_sold. Do this for each category of ticket.
The answer is correct. It has to do with when the increment/decrement occurs. For a fuller explanation, please check the relevant chapter in the text you are using to learn Java or online.

The number could be the actual arrival time.
Can each customer be represented by an arrival time in a specific queue?
The % sign means divide the two numbers and give us only the remainder.
How does c = 3?
For clarity, rewrite the code without using shorthand (augmented operators).
int a = 1;
int b = 2;
int c = 3;
a = a + 5;
b = b * 4;
Rather than using a nested for loop, which tends to confuse, how about using a counter for the size of the rows.
Well, Norm seems to advocate a real time simulation, whereas I propose just calculating and accumulating known (random) time intervals. You then pump them out in one go during runtime.
For the...
Just accumulate values you allocate and call them the time spent? Why do you need a clock if you know what the time intervals are?
The reset() method will reset the value of the scanner's radix to 10 regardless of whether it was previously changed. (ref)
Does your program work or what is the error message?
You would probably need 3rd party libraries (Apache) to read a doc file. Even then, I'm not sure it specifies pages. I'm no expert, but doesn't it get formatted when you open it so suit your default...
I count at least 5 classes:
Image_Filter
Steganography
Image_Panel
Steganography_Controller
Steganography_View
With the panel being quite problematic.
Where do you want to return the dns variable to?
System.out.println(s);
You can't print the 2d array with such a simple statement. You need a loop.
How come you are using ++c (preincrement)) and not c++ ?
BTW, the puzzle cannot be solved....
