Bingo Board - Having Array To Fill A Grid
Dec 16, 2014
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.
import java.util.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import java.awt.event.*;
import java.util.ArrayList;
import java.awt.GridLayout;
import javax.swing.JButton;
public class bingoboard extends JFrame

I am writing a Bingo program for a class and have reached a roadblock. How do I call 5 numbers from the array and where do I store them so I can populate them back into my JLabels on the Bingo card. I'm sure there are more complicated ways to do this, but I'd like to keep it simple so I actually understand the process. I understand that I will need to shuffle the numbers in the array before choosing them, but I also am not sure how to do that.
int [] BArray = {1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15};
for (int index = 0; index > 5; index++) {
}

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?

THE PROGRAM DOES NOT HAVE ERRORS. FILL THE 2D ARRAY WITHOUT DUPLICATES VALUES. AND DISPLAY IF THE ARRAY IS MAGIC SQUARE OR NOT.

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.
import java.util.*;
import java.io.*;
public class ATM2 {
public static Scanner kbd;
public static final int MAXSIZE = 50002;

I must fill a 2d array randomly and then apply methods to the array. However i keep getting an out of bounds exception no matter what dimensions i use. I have a test and a class program.
import java.util.*;
import java.lang.Math;
import java.util.Arrays;
import java.util.Random;
class SummerStats {
Random rand = new Random();

My validAccounts array has a null value in it when i print it. How to do this.
I am NOT allowed to use bufferedReader or ArrayLists. This must be done with loops.
import java.util.*;
import java.io.*;
public class ATM2 {
public static Scanner kbd;
public static final int MAXSIZE = 50002;
public static void main(String[] args) {
kbd = new Scanner(System.in);

i am to add jpanels to an arraylist such that it forms a grid like a 2d array. when i add the first colunm and have to iterate and store the next sequence of jpanels it still stores it in get(0), instead of get(1).
[/ temp.add(jPanel9);
temp.add(jPanel10);
temp.add(jPanel11);
temp.add(jPanel12);
temp.add(jPanel13);
temp.add(jPanel14);
temp.add(jPanel15);

I'm using JavaKara (a graphic Java software to learn coding) on my classes at the moment and we're asked to transform something like this:
In the inverse, where you can see clovers there must not be any and where there aren't you must plant them. PLUS YOU MUST SWITCH THE FIGURE HORIZONTALLY.
This is the result i should obtain:
public class InvertiECapovolgi extends JavaKaraProgram {
public void myProgram() {
boolean arrayquadrifogli[][] = new boolean[world.getSizeY()][world.getSizeX()]; //[rows][clumns]-->[Y axis][X axis] in kara
for (int y = 0; y < arrayquadrifogli.length; y++){ // My Ladybug starts to run through the whole grid
[Code] ....
How to switch everything horizontally!
This is my result:
My ultimate question is, how do i have to edit the second loop, and why, to obtain the horizontally reversed result i'm supposed to obtain?

What would be a good and simple algorithm to find the shortest route between two points in a 2D array[grid] ? There can be certain obstacles in the grid i.e. some of the cells may be inaccessible. I tried googling for it and found that A* is the best for this but I am just a beginner and would like to start with something much simpler.

As you may have known, I'm creating a Bingo simulator from scratch.
Precondition: an n amount of randomly generated cards are created.
Postcondition: After a number is called, cards that has that number will have its value be true.
For example:
Precondition
Java Code:
Card 1 //Name of card
1 24 32 48 63
2 22 41 51 64
3 16 37 52 61
4 19 33 57 72
5 20 34 54 71 //Card with numbers
false false false false false
false false false false false
false false false false false
false false false false false
false false false false false //Card with boolean values to indicate marked values
[Code] .....
So what I want to do is have a method that allows me to use the callRandomNumber method so that the matrix location with that random value is marked true for all of the boards.

I'm trying to create a program that will be able to generate random Bingo cards. This is what I have so far.
Java Code:
import java.util.Random;
public class BingoCard
{
private int[][] card;
public BingoCard(Random random)
{
card = new int[5][5];
for (int c = 0; c < 5; c++)
[code]...
The problem with this program is that even with the checkForDuplicateValues method, which checks for duplicate values of a column and replaces the values, it still prints out bingo cards with duplicate values!

My assignment is for a game where there is a board of colors and each player draws a color and moves to that position on the board. It will then output how many cards total in the game it took whichever player to win. If no winner it outputs the number of cards that none won by going through. I attached the file that corresponds with my code.
This is the desired output:
Player 1 won after 7 cards.
Player 2 won after 8 cards.
No player won after 8 cards.
Player 2 won after 4 cards.
No player won after 6 cards.
Player 2 won after 8 cards.
Player 1 won after 4 cards.
Player 2 won after 8 cards.
Player 1 won after 1 cards.
No player won after 200 cards.
Player 4 won after 100 cards.
import java.io.*;
import java.util.Scanner;
public class ProgrammingAssignment1 {
/**
* @param args the command line arguments
*/
public static int players;
public static int cards;
public static int boardlength;
public static String board;
[Code] .....
The output that I get is:
Player 1 won after 3 cards.
Player 2 won after 8 cards.
No player won after 8 cards.
Player 1 won after 3 cards.
No player won after 6 cards.
Player 2 won after 8 cards.
Player 1 won after 3 cards.
Player 2 won after 8 cards.
Player 1 won after 1 cards.
No player won after 200 cards.
Player 4 won after 100 cards.I guess I'm supposed to set the playerPos[] to -1, but I'm unsure how.

So I an assignment in Java to write a code which will randomly populate squares in a Tic Tac Toe Board. I pretty much have it I think, but I cannot get the 'O' to appear on the board, some squares will be blank. We were told to use the Random utility to generate the squares. I am attaching the .gif's which are used. Here is my code:
import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class LandryTicTacToe extends JFrame
{
/**
*
*/
private static final long serialVersionUID = -8781512780135301721L;
private final int HEIGHT = 450;//Set value for Height
private final int WIDTH = 500;//Set value for Width
private static JButton [] button = new JButton[9];//Declare array of Buttons
[Code] .....
[attachment=37084:TicTac0.gif][attachment=37085:TicTacX.gif]
Instructions Given to me:
Display a frame that contains nine labels, arranged like a Tic Tac Toe board. A label may display an image icon for X, an image icon for O, or nothing. Display images randomly in each label. Use the Random class to generate 0, 1, or 2, which corresponds to displaying an X image, an O image, or nothing.

I have a tic tac toe game and when i run it it works and there are no errors. but the X's and O'x do not show in the board. I know the problem is in the "gameBoard" method and its cause i am telling the code to print the same board every time but i dont know how to do it the right way....
package chap7MDA;
import java.util.Scanner;
public class chapexe7we {
public static void main(String[] args) {
char[][] board = new char [3][3];//make a game board
gameBoard(board);// call the method game board to make the board

I've been trying to make a class that has a toString method that displays the board at the same time displays the value of each index of a 2d character array inside of the code. My professor has made the client print the method. I assumed since he was printing it on the client we had to return a string that gives us this.The number 2 is part of the 2d character array while the rest of the index values are just space characters.

I had trouble figuring out how to return this so I started testing it out in another file.
public static void main(String[] args) {
// TODO Auto-generated method stub
char[][] myHidingPlaces;
myHidingPlaces = new char[5][3];
myHidingPlaces[0][0] = 'p';
char play = '1';
for (int i = myHidingPlaces.length-1; i >= 0 ; i--) {

I am trying to design a monopoly board game with a class and a main program. I can not make the method to keep track of the player's position after every roll. After every roll it prints "Previous position: 0".The player should also not go over 14th spot because the board is just 15 including 0. That is what I have (just the particular method and the part from the main program which call it).
public int getpospl1()
{
System.out.println( getplayer1name() + " Rolls "
+ "Dice 1: " + getrolld1() + "" + "Dice 2: " + getrolld2() + "" );
int spot1 = 14; //The end spot
int start = 0;
int previousPosition = start;

I'm back with a question about the Black Jack assignment. I've created a working game that works for one round, as well as a reset button that's able to clear the board of the old hand. However the runGame() loop, which checks whether a player has played his hand seems to freeze the program the second time around
private void initNewGame(){
dealer.addCard();
for(int i = 0; i < numberofplayers; i++){
players[i].addCard(); //draws card, adds score and paints card to the board
players[i].setStatus(false); //makes the buttons usable in the players[] class
[Code] .....
I know it's probably not optimal having an while loop constantly running to check the status, but I can't seem to figure out why it freezes.

Coding (must follow pseudocode algorithm provided) for comparing characters of a word to a puzzle board char[][].
I've gotten the horizontal and vertical searches to work, but I'm having a difficult time figuring out how to search diagonally.
Here's the search algorithm format I have to use:
for each guess word
for each letter of the puzzle
for each letter of the guess word
check for diagonal match
if found, add word to list, break to next guess
I'm assuming there should be a +1 horizontal offset after I find the first letter, but every index I've bumped has caused me to screw up my array bounds. I'm missing something.
Here's the algorithm I'm using for diagonal search. This same algorithm worked for vertical search (minus the offset of course)
//diagonal search
for(String word : guessWords) {//for each guess word
int letterCount = 0;
int index = 0;
for(int j=0; j<grid[index].length; j++) {//for each puzzle letter
[Code] ....

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.
