Multiple Message Boxes
Jun 4, 2015
In vb.Net, when I do the code msgbox("hello world") and put it in a loop, it will execute that command and show a new messagebox for every time the code goes through the loop. I am wanting to do something similar with java but I'm afraid I don't know how.I know that the following code will display a messagebox as I am describing it
Java Code:
JOptionPane.showMessageDialog(null, "message", "title", 1); mh_sh_highlight_all('java');
But when put in a loop, it does two things:
1) It hangs the program
2) It will only display the first message box and when you press ok, the other message boxes will be disregarded and not displayed (I'm assuming because of the hang).

For some reason the two JOptionPane message boxes at the end of my code don't seem to open when I run the program.

My application (e.g., the print dialog box) needs to support multiple languages (user selected either at starting application or by switch in code).
How can this be achieved under Windows 7, Enterprise (works OK under Linux). I have tried : E.g.,
Locale.setDefault( .. );
JComponent.setDefaultLocale(Locale.LANG);
Setting resource bundle
but to no avail. The application always inherit the Win 7 system locale.

for my class we have to make a rock paper scissors game using GUI boxes. Everything is working fine I'm just having trouble displaying what the computer chose. In other words, after the user selects Rock, paper or scissors, the scoreboard just pops up displaying the score. Here's the last working program before I started tinkering with it.
// your code goes here
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Icon;

I am able to generate text boxes. But I need one specific thing in that:
Through a drop-down I should select a number and those many text boxes should get generated.
Suppose I selected 4 from the drop down list. Then on screen it should display:
Student 1: Textbox
Student2: Textbox
Student3: Textbox
Student4: Textbox

I have to write an example program to fill boxes most efficiently with bags. All bags are the same size. The boxes come in Large, Medium and Small. Large boxes hold 20 bags. Medium boxes hold 10 bags. Small boxes hold 5 bags. I am getting input from JOptionPane input dialog box and then parsing that input to an integer.
I have to fill the large and medium boxes completely. I am not sure how to do this without an if statement. I can use one, but we have not covered it in class, so I am skeptical about using one to solve the problem. If I just divide the input number with integer division, I'm not going to get the remainder, right? So I'm thinking that I can mod my input number by 20 (the number of bags the user inputs) and then mod that number by 10 and then mod that number by 5, would that work?

From what I can determine check boxes are applied in SWT to the first column only of a table.
final Table table_project = new Table(g3_tabfolder_projects, SWT.BORDER | SWT.CHECK);
However I require check boxes on all cells. I tried creating a table for each column (which gives me my check boxes) but as the number of enries are often numerous and thus require vertical scroll the tables become out of sync (and to the user that sync is important).
Before I knock up some code to try and synchronise the tables I just wanted to check any alternative approaches. The project is SWT based.

I am creating a set of 3 subclasses, 1 superclass, and an application. In my instructions it says to make set methods in my super and subclass by using dialog boxes. In the application you have 3 different arrays where you create objects and are supposed to call the methods from the subclasses to be used in the application. I don't know how to make the dialog boxes from my subclasses to show up in my application.

I understand the basics of using the JOptionPane Message boxes, but how do i take the information that is entered and store it as a file, or print it. I'm in my 6th week of class, and this happens to be maintenance related.
import javax.swing.JOptionPane;
public class Example_Maintenance_System{
public static void main (String [] args) {
//Operator Name Input
String operator_name;
operator_name = JOptionPane.showInputDialog("Please scan your barcode");

I am working on a project in which I have three box (as of now) and each box will have some color of balls. So I am storing them in a Map of String and List of String as mention below.
Map<String, List<String>> boxBallMap = new LinkedHashMap<String, List<String>>();
Data in the above map is like this -
Java Code:
{box1=[blue, red, orange]}
{box2=[blue, red]}
{box3=[blue, red, orange]} mh_sh_highlight_all('java'); ProblemStatement:-
Basis on the above input, I need to return a mapping which will be List<Map<String, String>>, let's say for above input, below mapping would be return as an output -
Java Code:
[{box1=blue, box2=red, box3=orange},
{box1=red, box3=blue},
{box1=orange, box2=blue, box3=red}] mh_sh_highlight_all('java');
Here if you see, each row has alternate color of balls for each box - meaning blue for box1, red for box2, orange for box3 in first row. I cannot have same color of balls in each row. So this combination is not possible as it has same color of balls for two boxes in one row.
Java Code: {box1=blue, box2=blue, box3=orange} mh_sh_highlight_all('java');
And also, in the second row, I won't use those balls which have been used in the first row for that box. In second row, box1 has red why? bcoz blue was already used in the first row for box1 and box3 has blue and no box2 in second row.
The output combination is getting generated basis on the input being passed as shown above.
I started with the below code -
Java Code:
List<String> balls1 = Arrays.asList("red", "blue", "orange");
List<String> balls2 = Arrays.asList("red", "blue");
List<String> balls3 = Arrays.asList("red", "blue", "orange");
Map<String, List<String>> maps = new LinkedHashMap<String, List<String>>();
[Code] ....
Below is my method in which the crux of logic should be there
Java Code:
private static List<Map<String, String>> generateMappings(Map<String, List<String>> map) {
return null;
} mh_sh_highlight_all('java');
Below algorithm might work but still not sure how should I fit this in the code -
- sort the boxes by the number of balls they have in it (ascending, from the smallest to the largest box).
- while there are colors left
- loop over the sorted list of boxes
- in each iteration pick a color from the box (if there is one left), that is not already picked in the current iteration (of the while loop)

import javax.swing.*;
public class InstantMessageFrame extends JFrame
{
private JList friends;
private JTextField message;
private JButton send;
[code]...
1. Open the source code file of your InstantMessageFrame class from Lab 12.2.
2. Add the following three fields to the InstantMessageFrame class: a JTextField named message, a JList named friends, and a JButton named send.
3. Add a method to your InstantMessageFrame class named getMessagePanel()that returns a JPanel and has no parameters. (This method will create a JPanel that will appear in the south border of your JFrame. It will contain a text field in which a message can be entered and a button that sends an instant message to all the friends in the list.)
4. Within getMessagePanel(), instantiate a new JPanel and give it BorderLayout.Assign a message equal to a new JTextField by using the no-argument constructor of JTextField. Assign send to a new JButton,passing in "Send" to the constructor. (This will be the label on the button.)
5. Within getMessagePanel(), add the message text field to the center of the JPanel and add the send button to the east border of the JPanel. The panel is now ready, so return the JPanel reference.
6. Add a method to your InstantMessageFrame class named get-FriendsPane() that returns a JScrollPane and has no parameters.(This method will create a scrollable list that will contain the names of others that you can chat with.)
7. Within getFriendsPane(), assign friends to a new JList by using theno-argument constructor of JList.
8. Within getFriendsPane(), instantiate a new JScrollPane using the following statement: JScrollPane pane = new JScrollPane(friends);
9. The scroll pane is ready, so return the reference pane at the end of getFriendsPane().
10. Within the constructor of InstantMessageFrame, invoke getMessagePanel(),placing the returned panel in the south border of the content pane of InstantMessageFrame.An Introduction to GUI Programming 399
11. Within the constructor of InstantMessageFrame, invoke get-FriendsPane(), placing the returned scroll pane in the center of the content pane of InstantMessageFrame.
12. Save, compile, and run the InstantMessageFrame class.Your InstantMessageFrame now has three visible components: a JList,a JTextField, and a JButton.

if i send messages as in the code below, is there a way to read only one message, if the client doesn't know how long it is (or if he only knows the maximum length)?in the documentation it says, that the method read(byte[]) reads until no data ist available or end of file is decteted. What does the latter mean? Can i extend the array that i sent by a byte that signals the end? Here is my Code:
Server
public class Server implements Runnable{
ServerSocket server;
HashMap<Short,Socket> clients;
public Server(){
clients = new HashMap<>();
[code]....
Both are startet in seperate threads. At the moment the first output of the client is "12 bytes read", and then continously "-1 bytes read"(because the server closes).

I am new to the JMS technology. I have written one sample sender and receiver program to pass a string message to the JMS queue and retrieve it back. It is working fine as well. But now, I want to pass a xml file to the JMS queue. Then from there I need to read the XML file and convert it into a Java object Using Jaxb. I know how to convert an XML into java object using Jaxb. But i am unable to send the XML file as a jms message to the listener.

As a part-time student, you took two courses last term. Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.
