I am trying to write a program for a hairsalon, and I have a JDialog popup, where the user inputs the appropriate data for an appointment...
This includes a scrollpane with all the available services the hairsalon has to offer.
I create these checkboxes dynamically (using a for loop) after storing them in a Vector first
Java Code:
Vector<JCheckBox> checkboxVector = new Vector<JCheckBox>();
for (int i = 0; i < services.femaleServices.length; i++) // femaleServices is a string array holding the services for ladies
checkboxVector.addElement(new JCheckBox(services.femaleServices[i]));
for (int i = 0; i < checkboxVector.size(); i++)
servicesPanel.add(checkboxVector.elementAt(i)); mh_sh_highlight_all('java');
They are dynamically created for 2 reasons:
1) Many different services
2) User may add new ones over time...
The problem is I cannot reference them.
For example, if a lady wants to have a haircut and change her hair colour, 2 checkboxes will be checked... How can I know which ones are checked?
I have a random list of links whose title I am getting from the database. I'd like to catch one of these links when the user clicks one of them and process it from a single jsp file. Possible?
E.g.: when user clicks one of these links, can I dynamically call a web page that fetches information from the click and gets values from a database and insert it on JSP page....
I'm displaying a 3-column table with the column names ID, name, and salary. I made the ID into a link to go to the EditServlet class. What I'm trying to do is figure out which ID# was clicked to get onto the servlet page, how to implement that dynamically?
I know that if you put something like ?x=1 and then getParameter("x") on the servlet page would work, but then all the IDs would have the same parameters since I'm using a for loop to print out my ArrayList of objects.
I am working on shopping cart application in which i want to generate selectonemenu dynamically for setting Item attribute from database.for eg, I have 4 tables item, attribute,attribute_value and mapping of this three.

i made to display but get confused when it comes to storing this value in database confused in red underlined place..This is without any dynamic generation but i think solution is dynamic component but dont know how code snippets:
i'm trying to do a nested circle dynamically. i don't know whats wrong with my program ...
private Ellipse2D.Float doubleElip(int x1, int y1, int x2, int y2){ int x = Math.min(x1, x2); int y = Math.min(y1, y2); int width = Math.abs(x1 - x2); int height = Math.abs(y1 - y2); for( int i=0; i < 1; i++){ Ellipse2D.Float elip = new Ellipse2D.Float(x , y, width/i, height/i); } return elip; }
i want to draw a circle inside a circle in java. so far i'm using this piece of code
private Ellipse2D.Float drawEllipse(int x1, int y1, int x2, int y2) { int x = Math.min(x1, x2); int y = Math.min(y1, y2); int width = Math.abs(x1 - x2); int height = Math.abs(y1 - y2); return new Ellipse2D.Float(x, y, width, height); }
I am trying to create a form where my customer can add some other fields(like: label,textbox), and he need to use that added fields for the next time he open the application...
I would like to know whether it is possible to save dynamically created controls and reuse it again...
I'm having trouble conceptualizing something. I will post the code, it's works exactly as it should. I create an array and Hash Map to display periodic table of elements information after allowing the user to search by element name or symbol. I want the user to also be able to add elements to the periodic table. I can't really conceptualize how I am going to do that with an array I've already created.
Here's code:
//Create element objects. //Here is where I create my "elements" array, and where I could like to prompt the user to add elements, if desicred. Element[] elements = {new Element("Hydrogen", 1, "H", 1.008,1,1), new Element("Lithium",3, "Li", 6.94,2,1)}; // //Maybe it seems if I prompt the user here to add new element names, symbols, weights, etc, I would be overwriting
How load dynamically load jars? Is it possible to load updated jar in my application by code? My application has to use new and modified class files but application should not be restarted.

I'm writing a program to dynamically update an xml file to add, delete, and edit entries in the file. I've run into an issue with the add method because when I write into the file, a random letter is added before the line. EX:
I want to add "<item> ..." to the end of the list of entries, but when it is added, this is what is added "Z <item> ..."The spacing for the <item> is correct, however, I don't see where or why the Z is added.
public static void insertItem(Item i) { try { String insert = " <item>"; String text = ""; Scanner in = new Scanner(file);

I 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:
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.
I need to generate the word document dynamically using java code, included the necessary jar files, No compliation issue, but During run time am getting this error: Could not initialize class org.openxmlformats.schemas.wordprocessingml.x2006. main.CTDocume .using all these jar files: POI-3.6.jar, POI_3.9.jar, Poi-ooxml-3.5,Poi-ooxml-3.6,Poi-ooxml-3.7,Poi-ooxml-3.9,Poi-ooxml-schemas-3.6,Poi-ooxml-schemas-3.9.jar. using the XWPFdocument class. when my cursor get into that line XWPFDocument doc = new XWPFDocument(); getting the above error.
I have an assignment in which I have to design a method where I add an object at any given position in an array and shift the elements already in the array to make room. For example I have a collection class which holds trading card objects. So I wish to add a new trading card to this collection at a specified index or position with out deleting the current object already stored in the array . All this has to be done without the use of array lists, vectors or any abstract data types besides arrays . My question is how do I accomplish this . Say I wish to add a new trading card in position 4 the new card is added to my array and the card currently in position 4 gets moved to position 5 and the card in position 5 gets moved to 6 etc. The maximum amount of cards my collection can hold is 100. How would I add my trading card object to the specified position without overwriting what is currently there and shifting all other elements?Here is my current code.
public class CardCollection { public BaseballCard [] collection; final int MAX_CARDS = 100; public CardCollection() { collection = new BaseballCard[MAX_CARDS]; } public CardCollection(BaseballCard[]c)
[code]...
position refers to the position in the CardCollection and not the position inside the array.
I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description TextArea textArea = new TextArea(); Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT text.setText(usrNotes.getNote().trim());

If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.
In a project I'm ivolved in I have to dynamically add some components. All was going well until I had to generate data tables dynamically. I'm iterating a list of "SomeObject" and when I try to access a property of that object Glassfish tells me that object doesn't have such a property that is readable. I have getters for those properties and SomeObject implements Serializable as well. I used BalusC resources but I'm having no luck.
I am building a GUI application which consists of two panels "panel" and "panel1". "panel1" have a button "addTimer" when clicked it should add the "panel" to the frame if i gain click the button it should again add the "panel" without overlapping the previous "panel" rather it should be created below the previous "panel". If i click on the button "addTimer" n times it should add the panel n times. Along with this the frame size has to dynamically change depending on the number of panels produced. Below is the code i tried my level best to satisfy the above conditions.
package superTimerV2; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class SuperTimer extends JFrame { private static final long serialVersionUID = 1L;
