I want to make the board for the game, I want it to be a two-dimensional array of buttons.I know how to make a array but is there a class of buttons that I need to use? and how do I connect it to the xml?I am using eclipse.
View Replies I'm trying to make a simple battleship game, but when I make a ship with the addShip method (it is suppoused to initialize the board with the numbers 1,2,3 or 4 depending on the ship type, at the given coordinates) it dosen't initialize the field with any numbers, although the method returns true. The place the ship is suppoused to be made stays initialized with ".",
package battleship;
public class Sea {
private int width;
private int height;
private String[][] field;
[code].....
I'm working on a project and I can't seem to get it working. It is a battleship game, in a one dimensional array. This is as much as I got. I can't get the 'river' to display when I run the program. How I might get it to work?
import java.util.*;
import java.util.Random;
public class Battleship
{
static Scanner input = new Scanner(System.in);
public static int promptForInt(String prompt)
[Code] ....
I have an battleship program that I would like to improve in performance. I know that using certain algorithms it can be improve however I am beginner in Java. I would like any recommendations and or hint in how to improve this game. The are 5 ships per game and the computers plays 10000. I just want to sink all ships in as many shots as possible.
Main class
package solution;
import battleship.BattleShip;
import java.awt.Point;
import java.util.List;
[Code] .....
Code for implementing a simple computerised version of Battleships has been supplied. Examine the code ensuring that you understand it. The game is played against the computer.
A number of ships (default is 6) are place randomly on a 4 x 4 grid. A ship occupies one square only. The player then guesses the position of a ship. If he/she guesses correctly the ship is HIT and sinks. If the guess is incorrect the player loses a life. The default number of lives is 7. If the location has been guessed already, no lives are lost.
When the game starts, a 4 x 4 grid should be displayed.
The user should be allowed to enter/select a cell location. If the selected cell contains a ship, the ship will be destroyed. If not the player loses a life. The cell should display an appropriate picture, icon or message informing the user of its current state.
The number of lives and number of ships remaining should be displayed.
When the game ends an appropriate message should be shown informing the player whether he/she has won or lost. The positions of the ships should also be shown.
The purpose of this assignment is that students demonstrate an understanding of the Java Swing library and that he/she can navigate and use the API effectively.
Your finished GUI should be both user-friendly and aesthetically pleasing.
Ideally, the user should have the option to play another game, to quit or give up mid-game. You may also wish to include other options such as different levels of difficulty, etc.
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.

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;

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
[Code] ....
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 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 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

Having some trouble coding this exercise in JAVA:
Build a backtracking algorithm to place n queens on a chess board of nxn, with no threat to any queen.
Using F=parameter, Print only the first result.
Using the same C=parameter, print every possible inlays.
This should work when running with a 4x4 board and an 8x8 board basically.
I am trying to run a project and i am getting different errors, I know the code is working because i have seen it running, but now i cant even get the app to load up. sometime I get a AndroidManifest cannot be found error and sometimes i get a error like

I didn't see anything specific to Android. I am a very basic beginner when it comes to JAVA and Android programming.
The app is a very simple comic strip viewer that views 3 panels of a comic strip one at a time. My problem is going from a second activity to another. I can go from the main activity to the second fine but when I press the next button to go from the second activity to the third nothing happens. I have tried a few different things but end up with either nothing happening or the app crashes.
Here is my MainActivity Code:
package net.androidbootcamp.comicapp;
import android.support.v7.app.ActionBarActivity;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
[Code]...
Here is the code for the second panel:
package net.androidbootcamp.comicapp;
import android.app.Activity;
import android.os.Bundle;
public class Panel2 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
[Code]...
Here is the code for Panel 3:
package net.androidbootcamp.comicapp;
import android.app.Activity;
import android.os.Bundle;
public class Panel3 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
[Code]...
And here is the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="[URL].."
package="net.androidbootcamp.comicapp"
android:versionCode="1"
android:versionName="1.0" >

I am sure it is something very simple but I am not sure what it could be.
I have an integer variable called 'selectedname' which is declared as shown below.
public class MainActivity extends Activity implements View.onclickListener, AdapterView.OnItemClickListener {
int selectedname;
So when the app starts an Alert Dialog with two buttons asks the user if they want to tell the first or the last name. The two buttons are 'first' and 'last'.
The problem I'm facing is that in the code the value of selectedname is suppose to change depending on the users choice as shown below.
public void displayWelcome() {
//*other code comes here but it works fine*
AlertDialog.Builder choice = new AlertDialog.Builder(this);
choice.setTitle("Yo!");
choice.setMessage("First name or last");
choice.setPositiveButton("First", new DialogInterface.onclickListener() {
public void onclick(DialogInterface dialog, int whichButton) {
selectedname = 1;
