I 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.
I have 5 radio buttons in my gui, I have a reset button which I have resetting everything else but now I am looking to remove the dot from the selected RB when you press the reset.
View Replies View RelatedI 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.
Here'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?
How do you make it so that you can select 2 buttons in a radio button group? for example: If I have 7 radio buttons, and I want to be able to select 2 of the 7 instead of 1.
View Replies View Relatedi am very new to Java and i need to create a code that includes check-boxes, radio-buttons, and drop down menus. I decided to make a server order form and listed choices of appetizers, entrees, and desserts. I also need to create a button that combines all selected menu items and outputs the final food order. I also need to create a reset button.
View Replies View RelatedI am creating a shopping list, with each element and object called product from the Item attribute class. Each product object has a description, price, and priority. From user input, I am able to create each product object, and then .add to my arraylist. I know that it successfully adds because I have it printed in each iteration of the do-while loop. Once the user indicates they want to quit, the loop ends. I then want to print each description, price, and quantity but this for loop will only print the last element over and over. Here is what I have:
ArrayList <ItemAttribute> list = new ArrayList<ItemAttribute>();
Scanner keyboard = new Scanner(System.in);
ItemAttribute product = new ItemAttribute();
public void findDescrPrice() {
/**
* Get the item name (description) for each list item

Ok I am trying to auto populate a bean and retrieve the values from it using the jsp:useBean tags ect..
My code looks like this..

if(redirect.equals("create_account"))
response.sendRedirect("/WebProgrammers/sign_on_server_pages/"+redirect+".jsp");

I am having an issue with retrieving "grouped" data from HTML form to servlet. I will describe the scenario below.
In companies, they record the salary of the employees once a month.When they record it, they do not do it by visiting each an every employees personal "profile" (or whatever according to the system). Instead what they do is apply the salaries of all of them in one page.
To do the above thing they prefer excel like tabular sheets. Now, I have a html form, where the form content is a table. One row is dedicated to a one employee.
Below is my form.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
[Code] .....
As you can see, I have wrapped every row with a `<tbody>`. The `value` attribute of the `<tbody>` will contain the employee id. Once the form is submitted, the below servlet will capture it.
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
[Code] .....
What I was trying is get the `value` attribute of `<tbody>` (so I can identify the id of the employee) and get the data inside that `<tbody>`. However this didn't work, because I ended up with `NullpointerException` because it failed to read the `<tbody>` value.
So, how can I pass the data from table to servlet where it can clearly understand that one row is representing data belong to a one employee? If this is not the way to do it, I am also open for other methods.
I want to retrieve the data from this table given below and insert that data in the database in the next servlet
package com.sk;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

I did or at least thought I create a matrix of Buttons with values inside of them.
I will show code snippets from different classes:

for(int j=0;j<25;j++)

My IDE says counter cannot be resolved or is not a field. I understand what it is saying but why not? I try my best not to put a bunch of code on here.
A user can dislike/like a topic. However I have to submit buttons in my jsp file, the issue is that when a user presses like/dislike it should print out on the consile line. It does that perfectly but it prints out both when it should only print out either like or dislike.
My JSP code:
<form name = "ViewTripServlet" action="ViewTripServlet" method="post">
</br>
</br>
</br>
<input type="image" name = "like" value="submit" src=images/like.png onMouseOver="this.src='images/like.png'">
</br>
</br>
</br>
<input type="image" name = "dislike" value="submit" src=images/dislike.png onMouseOver="this.src='images/dislike.png'">
</form>
Servlet Code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ViewTri vT = new ViewTrip();
vT.user_like(request.getParameter("like"));
vT.user_dislike(request.getParameter("dislike"));

I have a question in mind that this is my registration form. I am sending these values from HTML form to server and database. I have question that in my case if I click next to Add Another Mobile no in HTML.then a block is genereated and each time a new name is generated.
My Question is if I click 6 times then 6 name attribute are generated. How can I send and differentiate them on my server side.
Because at their I will use something request.getAttribute("Attr_Name");
But they are same. How to do this?.
I want to set the values coming from database with multiple field's Through AJAX and Custom XML. How to do ???

I'm working on a GUI application, I'm building it based on an example of a image provided and I am having an issue with my radio boxes, well the easiest way to explain will be if you look at the too attached images , the example im working from has the radio-boxes transparent they are the same color as the background image, my radio boxes seem to sit ontop of the background image with their default grey border, How can i make my radioboxes blend into the background like in the given example?
Im using Netbeans GUI toolkip to build this app, for the background image in the jpanel i just created a label and set the icon to the image i wanted.
For the following code.When I run it ,I am getting the image and Login written along with it , but not getting the preselected radio button
import javax.swing.*;
public class MyJFrameWithJRadioButton extends JFrame
{
JRadioButton rdButton;
public MyJFrameWithJRadioButton()
{

rdButton =new JRadioButton("Login",new ImageIcon(ClassLoader.getSystemResource("Login.png")),true);

I am using Java Swing to create a GUI. I have some radio buttons on a JFrame that gets opened when the user makes a certain selection. I want to read a config file to have the radio buttons selected or deselected when the form is opened to indicate the current state of the radio button based on the saved config file.
How do I go about setting the radio button as selected (visibly selected) when I open up the JFrame?
I was trying to use RadioButton.setSelected(True); but this doesn't actually visibly select the radio button.
