Card Game War Comparing Rank
Oct 30, 2014
I am making the card game War, I have gotten fairly far without a huge snag but I have been working on this. I need to compare 2 cards to find the larger of the 2. I have a function that will do that, but it is comparing the wrong numbers. The function is comparing their index values but I need it to compare the card value. The card value is found at rank(card).
import java.util.Random;
import java.util.List;
import java.util.ArrayList;
import java.util.Deque;
import java.util.ArrayDeque;
import java.util.LinkedList;
import java.util.Collections;
[Code] ....

So I'm making a trading card game and each card can be moved around like chess pieces. So far, I've made the cards simple rectangles and detect if clicks are made within that rectangle and then move them appropriately, but I'm not sure if that's the best solution.

I am facing with a JAVA code needed for my assignment.We are implementing a Card Game.. There is a Card Class which i have not included in the code below .We have a Dec class that has various arrays..
privateCard[] masterPack >> Is a master Pack that is initialized once and has all the 52 cards.
private Card[] cards >> Is the array that has the card values from masterPack array.
My problem is :
After I called the Deck object D1, it goes to the Deck COnstrucutor OK.It then populates the values of masterPack as per the allowmasterPack method.Then it stores the values of masterPack into cards array in the init method..I get an exception when line below is executed..
cards[pack * 52 + k]= masterPack[k];
I get a java.lang.NullPointerException error..
public class debug
{
public static void main(String[] args)
{
int pack = 1;
Dec D1;
D1 = new Dec(pack);

I'm currently taking a computer program design class which has done a lot for my understanding of how to organize classes, but isn't giving me challenging enough assignments and I don't believe it's going to be covering interfaces and abstract classes, which is a shame. So I've been digging into these topics myself and decided to work on my own program (an Uno game program) that would utilize everything we've been learning and give me some practice with GUIs.
My current plan:
Have an abstract UnoCard class that determines the basic properties/methods common to all cards. Create a class for each card type extending from UnoCard, which would be - the generic card (number and color), action cards (skip, reverse, draw two), and special cards (wild, wild draw four, and blank).
Two enums, one for color, one for rank (which includes the numbers, as well as the action and special card ranks (reverse, wild, exc.) ).
A deck class would have an ArrayList <UnoCard> property and it's constructor would initialize a fresh deck.
A hand class that also has an ArrayList <UnoCards> where it gets said cards from the deck class.
A discard pile class, which contains the cards discarded and the current card in play.
A "board" class (haven't figured out a better name for it yet) which would determine/keep track of the number of players/hands, the turn order, the locations of the cards, and the winning condition.
Area of confusion and concern I'm having:
From what I've read, I want to avoid circular dependency. So if that's the case, when a card type effects the state of a "hand" or the turn order or really anything else, then in what class do I place the method(s) that effect that? If I place it in the specific card class, wouldn't that create a circular dependency? So would it be better then to have the hand class figure out what can be done with a specific card and what that specific card effects (which wouldn't that hinder the cohesion of the class?)?
I was also thinking a possible solution might be to have the non-generic card types contain methods that return values as apposed to manipulating higher level classes, such as a boolean drawCards which returns true if cards need to be drawn, false otherwise (same for skip, reverse, exc.).Then maybe the board class can determine what to do if those values are true or false (which actually seems more convoluted since only one value would be allowed to be true at any given time).
The other solution I was considering is to have a single UnoCardRules class, which serves the sole function of providing methods to determine the effects of each card, that way each card class can only worry about defining the card's state.

I am currently making a 5 card stud game for my Java Programming class at my highschool. I am deciding to go a little above expectations and make my poker game a little more fun than just comparing a few cards. However I want there to be text that is changing on my screen, but the repaint() is not the most reliable way to make the screen update, I am wanting a way for have the program constantly update the screen so that if I do something like someLabel.setText("Text"); then the text will update automatically whenever it is changed.
Here is my declarations and main/constructor method
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Random;
public class FiveCard extends JFrame implements ActionListener {
[Code] .....
Here is the method addMainPage, which is called in the constructor. Whenever the enterButton is pressed, the actionListener directs it to loadBoard();
I use GridBag Layout, so to skip through all of the constraints
public void addMainPage() {
for (int i = 0; i < 4; i++) {
players[i] = new Player();
}
Icon cardBackImage = new ImageIcon("back.gif");
[Code] .....
Game intro is a method that changes the text of a label every second using .setText(), however it does not work because the enterButton is pressed, then after loadBoard() and gameIntro() is ran, it repaints the frame with the board objects and the gameIntro's final .setText() command.The action listener is simple...
public void actionPerformed(ActionEvent e) {
if (e.getSource() == enterButton) {
players[0].setName(playerNameField.getText());
loadBoard();
}
p.repaint();
}

I'm creating a card game and I'm having trouble getting a card gif to display. A card is drawn from an 52 card deck arraylist, and I then need to match that drawn card with the similarly named gif in an arraylist of card gifs, to display the gif on a card GUI. I have put my game, card, deck and graphical class below:
Card -
public class Card {
public String number;
public String suit;
public Card(String n, String s) {
number = n;
suit = s;
[Code] ....
The arrayList of card gifs (which contains all 52 gifs for the cards) is in the graphical class and my arrayList that contains the deck of cards in textual form (that I've imported from a textfile) is in deck. The names of the gifs in the gif arraylist are the same as the card names in my textual card arraylist (for example, 3h.gif is 3h in my card arraylist), so I believe I can use a .equals statement to match the card that has been drawn to the gif.
Here is what the gifs look like in their folder, which is an arraylist in my graphical class :
Here is what the drawn card looks like after the textual card arraylist has been shuffled:
The brown card in that image isn't the displayed card that has been drawn, it's just a graphical deck that I put in, I can't get the card that has been drawn on the GUI to display on the actual card frame, as you can see.

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!

I am trying to call a constructor from PrepaidCard class in my main method, but I am not sure how to proceed.
As seen below, both the PrepaidCard constructor and the setCardID method have the ability to set the card ID.
Java Code:
public class PrepaidCard {
public PrepaidCard(String id, int token) {
cardID = id;
tokenBalance = token;
} public void setCardID(String id, int token) {
cardID = id;
tokenBalance = token;
}
} mh_sh_highlight_all('java');
Now in this block of code, I can successfully pass the id and token value by calling the setCardID method from the PrepaidCard class.
Now I would like to call the PrepaidCard constructor from the PrepaidCard class to pass the id and token value, instead of using the setCardID method.
Java Code:
public class PrepaidCardTest {
public static void main(String[] args) {
PrepaidCard card2 = new PrepaidCard(id, token);
System.out.print("Enter Card2 cardID: ");
id = input.nextLine();
card2.setCardID(id, token);
}
} mh_sh_highlight_all('java');
How to call the PrepaidCard constructor from the PrepaidCard class, to successfully pass the id and token value, in my main method?
Specifically how to modify or replace this line of code so that it can correctly call the PrepaidCard constructor?
Java Code: card2.setCardID(id, token); mh_sh_highlight_all('java');

I'm nearing the final development stages of my first game, but have run into a problem. I've constructed 4 different levels and allow the user to select the level they want to play from a central JPanel in a Card Layout system. My problem is that once a level is completed, I can't switch the JPanel which is displayed to start the next level, since I don't know how to access the original JPanel which acts as a driver for the other panels.

What it's supposed to do: This code is supposed to see if the clicked card is selected. If it's not, select it and show the player where it can move / attack. If it is selected, then find out what card the player clicked on. If he clicked on the card that was already selected, deselect it. If he clicks on a friendly card (same playerID), then select that card. If he clicks on an enemy card (different playerID), attack that card. If he clicks on a tile, move it to that tile.
The problem: However, line 24-58 give me a bit of a problem. Right now, it works fine BECAUSE lines 46-58 are commented (which also means the unit can't move). If I uncomment those lines, the unit becomes able to move, however, lines 34-46 cease working...
Java Code:
@Override
public void mouseClicked(MouseEvent e) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
if (Card.cardSelected == null) {// Contains / Is not selected
if (c.contains(e.getX(), e.getY())) {
Tile.reset();
Card.reset();
Card.cardSelected = c;

so bassically theres an array called "arreglo" which has the cards in order and the function "random" its an rng of numbers from 0 to 51.what i'm trying to do it's to take the cards from the ordenated array and put them randomly in the other but only if it's empty.(the array "mazo" has alredy been initialized with null).it worked at first, but now, after compiling succesfully i tried to run it and the cmd just...

I am new to OOP, i am not sure if this is the correct approach or not. Write a class named CreditCard that has (at least) the following member variables:
- name. A String that holds the card holder's name.
- cardNumber. A field that holds the credit card number.
- balance. A double that stores the current credit card balance.
- spendingLimit. A double that stores the spending limit of the card holder.
- Bonus: additional fields that you can think of.
In addition, the class should have the following member functions:
- Constructor. The constructor should accept the card holder's name and card number and assign these values to the object's corresponding member variables. The constructor should initialize the spending limit to $2,000 and the balance to $0.
- Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's member variables.
- purchase. This function should add the amount specified as a parameter to the balance member variable each time it is called.
- increaseSpendingLimit. This function should add 500 to the spendingLimit member variable each time it is called.
- payBill. This function should reset the balance to 0.
- Input validation: Whenever a credit card number is modified, verify that it is of reasonable length.
Demonstrate the class in a program that creates a CreditCard object and allows the user to change and view the state of the credit card with a menu driven program.
View Card Information.
- Purchase an Item: ask the user the purchase amount and increase the card balance accordingly.
- Pay Bill: call payBill method to set the balance to 0.
- Increase Spending Limit: ask the user how much the spending limit should be, and call the increaseSpendingLimit function the appropriate number of times.
[CODE]
import java.io.*;
import java.util.Scanner;
public class CreditCard
{
Scanner input = new Scanner(System.in);
//data members
private String holderName;
private int cardNumber;
private int accountBalance;
private double spendingLimit;

ABC is a company that designs and prints personal business cards. The company has asked you to write a Java application to display the layout of the information in a typical business card order. Data items in a typical business card include the customer's name, address, city, state, postcode, home phone number, and work phone number.
Write, compile, and test a Java class that displays these data items in a command window. Alternatively, you could also create it using a dialog box. Please include appropriate comments in your class.
Please named your class BusinessCard(LIM).java. (eq. BusinessCardLIM.java)

Opoly works this way: The board is a circular track of variable length (the user determines the length when the game app runs). There is only one player, who begins the game at position 0.
Thus, if the board length is 20, then the board locations start at position 0 and end at position 19. The player starts with a reward of 100, and the goal of the game is to reach or exceed reward value 1000. When this reward value is reached or exceeded, the game is over. When the game ends, your program should report the number of turns the player has taken, and the final reward amount attained.
In Opoly the game piece advances via a spinner - a device that takes on one of the values 1, 2, 3, 4, 5 at random, with each of the five spin values equally likely.
Although the board is circular, you should draw the state of the board as a single "line", using an 'o' to represent the current player position, and * represent all other positions. Thus if the board size is 10, then this board drawing:
**o******
means that the player is at location 2 on the board.
Here are the other Opoly game rules:
If your board piece lands on a board cell that is evenly divisible by 7, your reward doubles.
If you land on the final board cell, you must go back 3 spaces. Thus if the board size is 20, the last position is position 19, and if you land there, you should go back to position 16. (If the position of the last cell is evenly divisible by 7, no extra points are added, but if the new piece location, 3 places back, IS evenly divisible by 7, then extra points ARE added).
If you make it all the way around the board, you get 100 points. Note that if you land exactly on location 0, you first receive 100 extra points (for making it all the around), and then your score is doubled, since 0 is evenly divisible by 7,
Every tenth move (that is, every tenth spin of the spinner, move numbers 10,20,30,... etc.), reduces the reward by 50 points. This penalty is applied up front, as soon as the 10th or 20th or 30th move is made, even if other actions at that instant also apply. Notice that with this rule it's possible for the reward amount to become negative.
Here is the driver class for the game:
import java.util.*;
public class OpolyDriver{
public static void main(String[] args){
System.out.println("Enter an int > 3 - the size of the board");
Scanner s = new Scanner(System.in);
int boardSize = s.nextInt();
[Code] ....
heres the methods:
REQUIRED CODE STRUCTURE: Your Opoly class must include the following methods (in addition to the Opoly constructor) and must implement the method calls as specified:
playGame - The top-level method that controls the game. No return value, no parameters. Must call drawBoard, displayReport, spinAndMove, isGameOver.
spinAndMove - spins the spinner and then advances the piece according to the rules of the game. No return value, no parameters. Must call spin and move.
spin - generates an integer value from 1 to 5 at random- all equally likely. Returns an integer, no parameters.
move - advances the piece according to the rules of the game. No return value, takes an integer parameter that is a value from 1 to 5.
isGameOver - checks if game termination condition has been met. Returns true if game is over, false otherwise. No parameters.
drawBoard - draws the board using *'s and an o to mark the current board position. Following each board display you should also report the current reward. No return value, no parameters.
displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward. No return value, no parameters.

Let's get it out of the way -- I'm stumped. On something that should be pretty simple to solve. Code follows.
public class Sum {
public static void main(String [] args) {
Double nSum = 0.0;
Double aDouble = 100.0;
for (int i = 0; i < 1000; i++){
nSum += 0.1;
[Code] ....
The output:
100.000000
100.000000
false
false
false
false
false
Process finished with exit code 0
I wrote another simple program and hardcoded the values: aDouble = 100.0; bDouble= 100.0000
Using aDouble.equals(bDouble) returns true, just as one would expect.
So what am I overlooking?

System.out.println("fish.returnHash()" + (fish.returnHash()));
System.out.println("trialSearch.returnHash()" + (trialSearch.returnHash()));
the output is as follow:
hash compare false
fish.returnHash(){T=[1, 2, 3, 5], G=[], A=[0], C=[4]}
trialSearch.returnHash(){T=[1, 2, 3, 5], G=[], A=[0], C=[4]}
why is it printing false for the boolean statment when the two hashmaps contain the same values and keys?

With the following lines, if I type a print command instead of return, I get "ly". Yet if I aks to compare the result (which is "ly" as I can see with a print command) with == "ly", I get false?
What I also don't get, is that if I tye the programs in javascript, in that language the program works.
String str = "Oddly"
