Game Loop Freezing - Reset Button To Clear Board
Nov 9, 2014
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.

Im trying to make a tic tac toe game that you play against the computer using a random number generator and two dimensional arrays for the game board. Im not trying to make a GUI, the assignment is to have the board in the console, which I have done. I have run into a few problems with trying to get the computer player to correctly generate 2 integers and have those two integers be a place on the game board. Here is my code so far.
import java.util.Random;
import java.util.Scanner;
public class TicTacToe {
private static Scanner keyboard = new Scanner(System.in);
private static char[][] board = new char[3][3];
public static int row, col;
[Code] ....

I have to write a program that will generate 20 random circles with random radius lengths. If any of these circles intersect with another, the circle must be blue, and if it does not intersect, the color is red. I must also place a button on the JFrame. If this button is pressed, it needs to clear out the JFrame, and generate a new set of 20 circles following the same color rules. I am extremely new to Java Swing and am really stuck. I have everything working except the button. I cannot get a new set of circles to generate.
import java.awt.Graphics;
import javax.swing.JPanel;
import java.util.Random;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

The problem i believe is that I have the max value set to the first value given out, but every time the loop repeats the Max value gets reset to the next value in the file.
Essentially the program is supposed to read a list of credit card transactions and tell the user which transaction is the highest.
Here's the list of the sample file, note that the number of transactions could change that's why i haven't tried simply passing the values to method.
Bicycle 562.90
Groceries 138.43
Hotel 612.00
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
public class CreditCards {
public static void main(String[] args) throws IOException {
String fileName = "C:/Users/David/Desktop/CreditCard.txt";
File inputFile = new File(fileName);

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 got my clear button to work on most of the stuff I want, however I cant figure out how to fix the price to stop adding up. e.g. hit a button image with a price of 599.99, hit the clear button to empty, select price of 599.99 again then it display 1199.98.
sofa method
if (source == jBSofa) {
System.out.println("Sofa"); {
dTotal = dTotal + 599.99;
jTotal.setText(Double.toString(dTotal));
jTotal.setText(String.format("%.2f", dTotal));
}
Reset method
private void Reset() {
jTTotal.setText(" ");
jTotal.setText(" "); //sub total clear
jTTotalTotal.setText(" ");

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;

How do I track player (piece) movement?Building on the movement, to capture the piece you don't jump over it as in checkers, you move your piece onto the other color, so...How do I count pieces captured?
I'm really struggling on the physical code part. Conceptually I get that I need to store the information of each button clicked, but I don't understand HOW to store it, HOW to move a piece, and HOW to implement a system of turns.

I'm doing old projects . This loop will take any number, sum it and when you press the ESC button the loop will end and you will be shown the sum.
Java Code:
import java.util.Scanner;
class Sum {
public static void main(String[] args) {
int sum = 0;
System.out.println("Please write a number, end with ESC button");
Scanner in = new Scanner(System.in);
int number = in.nextInt();
[Code] ....
Here is the error
Java Code:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The operator != is undefined for the argument type(s) int, null mh_sh_highlight_all('java');
So well, the int ain't boolean says itself. also null ain't that for string ?
The original project was to get the number using one dialog box, convert the string to int and run the loop, so when you pressed ESC there then the return would be null.

I'm writing a simple application, that provides a Swing GUI to a bounded-buffer problem. The application is composed by:
- Main.java: it creates a map of four threads (four instances of the class MyThread). Also it creates a shared database (an instance of the class Database) between the four threads.
- MyThread.java: it's an extension of Thread, and it shows a Swing GUI associated to this thread. Each thread is associated a GUI.
- GUI.java
- Database.java: it's an extension of ArrayList and and it can contain a maximum of five elements. An element is an instance of the class User. Also it implements put() and extract() method consistent with the algorithm of bounded-buffer problem.
- DatabaseException.java: it's a simple message.
- User.java
public class Main {
public static void main(String[] args) {
Database db = new Database();
Map<String, Thread> tdg_m = new HashMap();
for (int i = 1; i <= 4; i++) {
tdg_m.put("T" + i, new MyThread(db));
[Code] .....
The issue is the following. When the database is full, and i try to put an element, the GUI freezes. The same problem occurs when I try to extract an element from the empty database.

Currently we are facing a problem in application developed in JSF, Hibernate on Tomcat server 7. The UI is getting freezed after uncertain time. Sometimes it worked for 2 to 5 hours and sometimes it hangs out within 10 mins, too.
Session time out in web.xml is -1
Before, we were getting memory leak logs in catalina, so we implemented ClassLoaderLeakPreventor in the application. When problem occurs, below log is printing in catalina.out.

What's wrong with my code. It says 'you win' even when I guess an incorrect number. And then the 'win' message keeps repeating. I'm thinking I need a way to generate a new input? And then maybe take the 'win' message out of the loop, but that breaks it too.

We have a weblogic based application, which runs Applet at the client side when the application is launced.
the application is getting freezed for a client.
how we can analyze the cause of this behavior,
1) As to how we can take thread dump or any other details to analyze the issue.

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]...

I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
Here is the code from my CardLayout:
import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JButton;
[Code] ....
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CheckerBoard extends JPanel implements ActionListener, MouseListener {
// Main routine that opens an Applet that shows a CheckerBoard
public static void main(String[] args) {
new CLayout();
[Code] ....
Once again kept to a minimal.
