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 am trying to use JTextField. I have windows 7.I have jdk 8u45. I am trying to use multiple text boxes. I have written the following code:
import javax.swing.*;
import java.awt.*;
class Avg5Nums{
int num1, num2, num3, num4, num5;
double Avg;
Avg5Nums(int val1, int val2, int val3, int val4, int val5) {

How to create text fields, labels and input boxes on a GUI, we haven't covered these in class as of yet, but I want my project to stand out so I'd like to know how to build a GUI now.
View Replies View RelatedI have list of employees in my database and their associated information like employeeId,supervisor and process. I have class named EmployeeDetails having same properties. I am fetching details of all users using below code:
<%EmployeeDetails employeeList;
employeeList=(List<EmployeeDetails>)assetmain2.getEmployeeList(loginName);%>
<table>
<tr>

In employeeList, we have list of objects having data of employees. I donot know how to get which object is selected in dropdown and based on that rest of the text fields are populated. Example:
Name ID Supervisor
-------------------------------------------------------
Pawan Kumar3033045Vimal Kumar
Vimal Kumar3040901Dinesh Hemrajani
If Pawan Kumar is selected from dropdown then '3033045' and 'Vimal Kumar' should get populated.

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).
I am trying to create a new text file in FTP Server using FTPClient but im not able to do. By using storeFile method i can only upload file that is already exists in my local system. But my requirement is to create file directly into FTP Server.

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.
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.
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 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)
I am familiar with Java but new to JSP. I have a Java Servlet app where user actions are recorded in a SQL Server database amd I now need to quickly put together a JSP front end application to view user actions. I want two drop down boxes to filter the results that will be displayed in a list box. What I need is the first drop down list box to show unique user names that have logged in. I can interrogate the database with the following SQL;
"SELECT DISTINCT(USER_ID) FROM AUDIT_MESSAGE"
Then when a user is selected from the first drop down list box (perhaps some sort of on change event) a second drop down list box shows the logins times of the selected user. Again I can interrogate the database with the following SQL;
SELECT SESSION_ID, EventTIME FROM dbo.AUDIT_MESSAGE
WHERE OPERATION = 'loginResponse' AND RESULTS = 'OK'
AND USER_ID = 'firstdropdownlistselection'
Then finally when a login time is selected in the second drop down list box all events for the selected user while logged in with that login time are displayed in the list box.
I have a jsf form which has a drop down. When I select any value in drop down it shows related details. When I use chrome browser, and I press back space key it comes back to the page, it keeps the value selected which was selected earlier, but in the firefox, IE it keeps the zero index selected. The same code is not working for chrome browser.
I would like the zero index to be selected in the drop down in previous page in chrome browser also when back space key is pressed...
