How To Deal With Exam Like PDF - Fill In Oval Image
Feb 1, 2015
So, let's say I have a pdf that looks like an exam or anything that has answer choices and an oval to fill in.
So, if I want to create a program that fills in some of those ovals, I would first need to find the coordinates? I can use something like gimp?
And once I have those coordinates, what do I do? Like do I extract the oval image and replace it with a filled in one? Is there a library that lets me do this - also lets me set the size to make sure the new filled in oval image is the same size?

We are making a tic tac toe game for my CS120 class and I am having trouble figuring out how to make our X's and O's. Is there a way to make shapes besides making two lines for an X and an oval with a white smaller oval inside to make an O? We have only learned the basics so far in class (i.e. events, inheritance, client-supplier, etc.)
These are our instructions:
Write a controller that controls the game. There is one human player (the X player) and the computer player (the O player). The name of the class must be TicTacToeController. In a sense, the controller is the game since the controller will 1) create a TicTacToeModel 2) create a TicTacToeView and 3) create a TicTacToeButton (you must write this class following the design pattern covered in class lectures), a label, and text field such that when the button is pushed, the player moves into the cell selected by the text field. After every player move, the computer moves into a randomly selected empty cell. When the game is over, a text message must be displayed somewhere on the screen the gives the status of the game. While you are free to change the appearance of the controller, the basic elements must be provided (a view of the game, a button, and a text field to enter the cell). A sample screenshot is displayed below.And this is the code i have thus far:
[import java.awt.*;
import javax.swing.JFrame;
public class TicTacToeView extends Rectangle
public TicTacToeView(int x, int y, int w, int h) {
super(50,60,w,h);
this.setBackground(Color.red);
JFrame win = new JFrame("Tic Tac Toe");
win.setBounds(10,10,w+100, h+100);
win.setLayout(null);
win.setVisible(true);
win.setBackground(Color.gray);
[code]....

What I am trying to do is extract the digits from between the words 'deal' and 'of'. I was wondering if this was possible to do with a regular expression or if I should just use a scanner.
UNIQUE Passive - Cleave: Basic attacks deal 20% to 60% of total Attack Damage as bonus physical damage to enemies near the target on hit (enemies closest to the target take the most damage).
Is there a regular expression that I could use in order to extract the '20' and the '60' from the above text. Below is what I have tried, but does not work.
(?<=deals)(d+(?=%))(?=of)
just to make a clarification, these numbers will not be the only numbers and the strings themselves will change. Everything can be considered a variable. The only constants between each string would be the words 'deal' and 'of'. The regex pattern "d+" is not a viable expression for my case

I have table data I'm trying to read . However one column is populated with the word "null". I guess java does not like dealing with the word null and throws errors.
When I try a block like : if ( rsrow.getString(insCol) = "null") {
I get and error .
If I try :
cmp = rsrow.getString(insCol);If I try:If I try:
if (cmp = "null") {
I get an error
If I try to use a replace function like:
System.out.println(cmp.replace("null", "0"));
Just to see if replace works I get and error.
What is the BEST way to replace this string value with something like "0" when I come across it with out jave throwing an error? I want it such that every time I come across the word "null" I can repalce it with "0".
Something like:
if (rsrow.getString(insCol) = "null") {rowofdata = rowofdata + "'0',"; } else {rowofdata = rowofdata + "'" + rsrow.getString(insCol) + "',";}

I have written a program to enter a name in a text box of an html file, get the name in a Servlet, search for the name in the database and inform the user whether or not the name is in the database via an applet. I'm trying to get the information from the applet to display in a colored oval, green w/white font if the name is in the database and red w/black font if the name is not in the database. I can get the information to display just not in the colored ovals and text that I want, I am including only the applet code, not the HTML or Servlet.

I'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.
I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".
If the user enters "21" and "22", it should output "**".
There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example
Enter number =
21
22
44
66
44
23
11
111 (the 111 is where the program breaks and moves on)
So it should then display
0-29 ****
30-39
40-69 ***
70-100
Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter
Here is the code
int mark = 0;
int range1 = 0, range2 = 0, range3 = 0, range4 = 0;
int count1 = 0, count2 = 0, count3 = 0, count4 = 0;
while (mark >=0 && mark <=100) {
[Code] .....
"The problem is with the while loop, the one above is something I was experimenting with "

I need to write a program but I am having hard time filling an array of triangles...we are suppose to have 3 different classes..1 class of points..1 class of triangles and 1 main method which apply all those..here what I have been come up so far for the point class which I believe is good..
public class Point {
private float x;
private float y;
//Making x equal to the x coordinate and y equal to the y coordinate like on a graph
public Point(float xCoordinate, float yCoordinate) {
x = xCoordinate;
y = yCoordinate;
[Code] ....
Now here is my question how I am suppose in the main method fill an array of triangles for 100 triangles or less?

We get a database and some DAO classes. We had to fill a ShowPanel with different shows being given in a theatre, and then when you choose from this you get several dates. Then when you click a date, the seatings appear in the SeatPanel. I got the first part with the shows and dates. But Im stuck at getting the seatings.We have a controller class which calls the shows+dates (this happens in one method). But i always get a nullpointerexception for the seatings. (this happens in a different method). I think i just don't know how to link the chosen show+date with the seatings.For the moment i have
public ArrayList<Seats> getSeating() throws SeatingException{
Show s = shows.getName();
ArrayList<Showdate> showdate = s.getDates();
ArrayList<Place> seating = new ArrayList<Place>();
try{
for (Showdate sd : showdate ){
[code]...
The given class PlaceDao has a static getInstance() method and an ArrayList<model.Place> getSeating(model.Showdate showdate) method.In the next stage i have to try and fill the panel with the seatings, but first i need to be able to call them.

my validAccounts array will not fill properly and has a null value in it.I added a print statement that prints the contents of the array and it is filling correctly but the very last value is null. I am supposed to be asking the user for a account number and password and it is not printing out correctly due to the fact that the array is not filled correctly.

I have to write an example program to fill boxes most efficiently with bags. All bags are the same size. The boxes come in Large, Medium and Small. Large boxes hold 20 bags. Medium boxes hold 10 bags. Small boxes hold 5 bags. I am getting input from JOptionPane input dialog box and then parsing that input to an integer.
I have to fill the large and medium boxes completely. I am not sure how to do this without an if statement. I can use one, but we have not covered it in class, so I am skeptical about using one to solve the problem. If I just divide the input number with integer division, I'm not going to get the remainder, right? So I'm thinking that I can mod my input number by 20 (the number of bags the user inputs) and then mod that number by 10 and then mod that number by 5, would that work?

I am attempting to make a 5x5 bingo board. My array generates 75 numbers(15 per bingo letter) and displays them in a random order. What I am having trouble figuring out is how to fill the 5x5 grid with 25 numbers from my array. And yes, my code is probably much longer and much more redundant than it needs to be. Also, I think I'm using cells and grids terribly wrong (possibly the entire java language) but I'm not sure.

I have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.
ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...
I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name
ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....
What am i doing wrong here, and how can i fix it to where it fills out the correct data?
Here's my code so far:
public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;
[code]...
I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.

I have an excel spreadsheet, with a specific filename and location which doesn't change (e.g. C:/workbook.xls)What I would like to do is have a window open when I open an .exe file, and in this window is a bunch of check boxes, text areas and drop down boxes (I can implement these, that's about my level of JAVA)
Then, when I click on a button in this window (for example, a button which says "Save"), the data from all these boxes and menus etc. goes into specific cells in the excel spreadsheet. Or if certain values are selected from a drop down menu, then a bunch of cells are empty.

I'm having trouble filling in the blank squares on a Minesweeper game. What I am trying to is, if a user clicks a square and that square(s) does not have a bomb in it, or adjacent to it, should be set to an empty square.
Here's my recursive method below:
public void revealZeros(){
for(int x = -1; x <= 1; x++)
for (int y = -1; y <= 1; y++){
Square zeroSquare = (Square)board.getSquareAt(xLocation+x, yLocation+y);
if (!(zeroSquare.SquareHasBomb)){
setImage("images/empty.jpg");
}
}
revealZeros();
}
I am traversing around the square that the user clicks on with the use of two for-loops. Getting the square at that location and then applying an empty square image. On that square.
The function should then recurse itself and go onto the next square, if the next square does not have a bomb or does not have an adjacent bomb.
I keep on getting an infinite recursion problem

Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
