Mouse Clicked Error - Selecting Card?
May 27, 2014
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;

I am working on a simple app that should emulate a desktop with some icons that you can drag around. I was instructed to use the MouseListener and MouseMotionListener. The icons should drag starting at the point where the mouse originally clicked down on it (ie not dragging from the top right corner).
I am drawing my icons to a jpanel, and I seem to be having two problems:The hitboxes are offThe icon is being dragged from the top right corner, despite having setup up a mouse offset at the beginning of the drag..Here are the relevant classes, the Desktop.draw() method is being called from my DrawPanel

I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).
Here is my code:
//form window class
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class formWindow extends JFrame {
private JTextField instructions1;
[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 having an issue with my swing gui. I dynamically create tabs with information (textfields, checkboxes, combo boxes) and when I select the checkbox it disables or enables a textfield. Now when I select the checkbox it seems to resize everything, specifically my textfields from say 9 columns to probably one. I"m a little unsure why it is doing this but I have a feeling it may be an inheritence issue.
My code is below for my generation of the tabs and of the rest of the information on the gui. The gui is an inner rid layout with a top and bottom pane that are both gridbaglayouts and an outter pane as well. I am thinking I am missing something in the grid layout setup that is causing this.
private void initComponents() {
jTabbedPane1 = new javax.swing.JTabbedPane();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
getContentPane().setLayout(new java.awt.GridLayout(1, 0));
pack();
[code]....

I'm learning Java using BlueJ, I have made a class that has a HashMap of (String, String) that contains an the make of a car and the model.
I want a method to return a collection of all the keys that satisfy a condition, like if someone wants to find what make a certain model is. I know it requires a loop, just not too sure how to write the loop to satisfy the condition.

I have a selection listener attached to a TreeView as shown below
treeView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<TreeItem<Pair<VideoSourceType, String>>>() {
@Override
public void changed(ObservableValue<? extends TreeItem<Pair<VideoSourceType, String>>> observable, final TreeItem<Pair<VideoSourceType, String>> oldValue, final TreeItem<Pair<VideoSourceType, String>> newValue) {
// do something
treeView.getSelectionModel().clearSelection();
}
};
What I want to do is to "do something" and then clear the selection so that it can be selected again. However, I cannot re-select the same item from the TreeView until I first select a different item.

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 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).

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 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;

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.
MainFrame.java

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();
}

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 using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file
