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

Mutually Exclusive Radio Buttons
Dec 15, 2014I am trying to create a JFrame where I have two radio buttons (choose one room or two rooms), but they need to be mutually exclusive. I know there is a lot missing from my code, but I'm trying to work through one issue at a time
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JCottageFrame extends JFrame //implements ActionListener
{
final int ONE_ROOM = 600;
final int TWO_ROOMS = 850;
final int ROWBOAT = 60;
int price;
[code]....
I believe the errors are because I am trying to add the radio buttons to the button group and making them mutually exclusive, but I'm struggling to follow the textbook on how to properly do this. When I remove the two lines of code that are causing the errors, my code compiles and the JFrame shows correctly. The only issue is that it is allowing me to select "One room" and "Two rooms" at the same time.

Swing/AWT/SWT :: Add Radio Buttons To ButtonGroup Dynamically?
Dec 5, 2014I am using a HashMap to store names (keys) and IDs (values). I have set it up so that the radio buttons are added to the JPanel dynamically. That is, each time a name/id is added, a new radio button is automatically generated and added to the panel. Here is a snippet of the code I have thus far:
private void employeeButtons() {
buttonPanel = new JPanel();
buttonPanel.setLayout(new GridLayout(5,2,5,5));
empMap.put("Kyle", "1090");
empMap.put("Alex", "6490");
empMap.put("Mark", "9090");
empMap.put("Anne", "4390");
[code]...
The above code adds all of the radio buttons to the panel just fine. However, I need the buttons to be mutually exclusive. I would like to be able to not only add the buttons dynamically, but I need the buttons to be added to a ButtonGroup dynamically as well. That is, when I add a new hashmap entry the a new radio button is generated and added to the radiobutton group.
Applets :: Adding Set Of Radio Buttons - Only One Instance
Jun 5, 2014Here's the situation before I inherited the project: There was an applet with a browse button. There was also another button that was not part of the applet. Clicking on the button launched a process with the selected path as a parameter.
Here's the situation now: I added a set of radio buttons to the applet. Selecting a radio button populates a variable with the selection. However, I have discovered that clicking on the button now launches another instance of the applet, so that the radio selection is not preserved.
What is the best and shortest way to preserve the value of the original selection?

Button To Reset View Of JFrame
Jan 23, 2015I 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.

Stuck In A Loop - Max Value Gets Reset To The Next Value In File
Mar 14, 2014The 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;

JSF :: Reset Values In Back Form Bean
Jun 3, 2014When we have a jsf form to store clients in a ddbb for example and the backing bean is in session scope.... Lets think of a user that requests 3 times the xhtml view with the form to store 3 clients.
1) If we dont reset the backing bean each time the form is processed, he would see the values he sent beforea and it doesnt have much sense, right?
2) Here there is an example of clearing form after submitting : [URL] ...... Clearing the form after submititng is a common practice for the reason of the statement 1, right?
3 ) What is the best or normal approach to reset values in a form? when the user requests it or done automatically by the application after processing a form?
4) Are there known issues about resetting or not resetting the values in a form bean?
Servlets :: Reset URL To JSP File After Servlet Call
Feb 14, 2014I am a JSP/Servlet newbie currently adding the first servlets to a web site that had been static all along. My local instance worked great but the servlets did not respond on the test instance. Apparently, my hosting service provider requires me to use an invoker servlet mapping.
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
Adding this to local web.xml broke the application but the servlets respond on test instance (when their calls are not preceded by another servlet call). A Servlet fails when it is called immediately after another servlet has been called.
What I saw happening on test is URL for first call is of the form:
xxx.org/<app-name>/servlet/<servlet-name>?Id=1
And URL for the second call became:
xxx.org/<app-name>/servlet/servlet/<servlet-name>?Id=1
The servlets are invoked using "href=servlet/<servlet-name>?Id="
How can I avoid the inclusion of 'servlet' in the URL and reset the URL to the JSP page it navigates to after processing of the servlet?
P.S.: I am also trying to enable the Invoker servlet on local so I can troubleshoot easier. I went through the changes to Tomcat's web.xml and context.xml. However, my local servlets did not respond even after calling them using "href=<servlet-name>?Id=". Is there a way I can check if my invoker is active?
