What I want is ..on selecting heading check box...all the below check box should get selected....and clicking on delete button which i will create later on...i want multiple rows to be deleted from database....
This is my insert.jsp page I want to insert multiple values into database Including multiple values of checkbox, other values are getting inserted but only problem at selecting multiple checkbox values in same column and radio button value in same column.
---------------------look for servlet page below----------------
Connection con = null; ResultSet rs = null; PreparedStatement pst = null; int user = 0; String User_Id1 = null; String Other_Services = ""; String Title = request.getParameter("Title");
[Code]...
Is there any solution to insert this...By mistake in query I have followed with extra questionmark in following line This is correctline for inserting 5 values in database
I am trying to finish this servlet that adds a new course to my courses display. im using a check box so the user can pick what the prerequisite are for the new course they want to add. so if they check cs201 , it will add cs201 as a prerequisite for that new course.
for some reason my checkbox will only add the first checkbox that is clicked. like if i add a subject , and click the check boxs for cs203 , cs202, and cs201. it will only grab cs201 and add it to my course display. it wont grab all 3. how can i grab the other info thats checked?
I would like to know how we can deploy one Web application on multiple server to share the work between them? My first thought is that we just deploy the same war file on different servers that connect to the same database. However, what will happen when a user enter something like [URL]? How can multiple servers share the same domain name and how the requests from different users are redirected to these different server?
I need to write server side program(Servlet) which must be access by several requests at same time.how to handle this using java? Do i need to use queue or multiple instance of same class. Any example server method which returns the results based on ID
public String getResut(int id){
1)get db connection 2)get the result from db 3) retun the result }
The output of value="${user.id}" is retrieved from a DB, it looks like this:
Id Nombre usuario Email Fecha de registro Acción 1 isaac2 @2 1986-01-01 *Delete(input) *Here there is check box 2 isaac3 @3 1988-01-01 *Delete(input) *Here there is check box
Then depending of which check box I selected then the row by the side should be selected by id and deleted.But what happens is that doesnt matter which check box I select, always the first row is deleted. I understand that at the first iteration of the loop it just take the first id, it doest attach the id I have choosen to the row it belongs to
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");
I am having an issue deleting a node for a tree for one of the cases.The cases for deleting a node are:
1. if its the root set it to null 2. if its a leaf, have its parent point to null 3. if the node you want to delete does not have a right child, have deleted nodes parent point to delted nodes only child 4. find the nodes predecessor(next largest value), have have predecessor's left child be deletes left, and preds right to be deletes right. then have deletes parent point to pred and finally, delete preds old spot (the one that is giving me an issue, I believe)
The pre order of the tree I am currently on is 50 5 4 10 190 100 100 200 190 201
I am trying to delete 190 (which should be the first one)but when I try to print out the list after I delete, I get a stack overflow error when I try printing everything out.I am pretty sure that it has something to do with me hooking up the nodes incorrectly since error occurs for case 4, since it prints out just fine when I deleted previous nodes (like a leaf).Here is my delete method: (note, ignore my determineX and checkOtherHalf methods)
public boolean delete (E item) { if(root == null){ return false;
else if(item == root){ root = null; return true;
[code]....
I have confirmed that it is a pointer issue: I need to assign replacements old parents left child to null, to stop it, but idk how.Here is a screen shot of it when I debug it
I've a ArrayList with dogs on, and I've a function that should allow me to delete a dog from the register and if the dog was found it prints "The dog was deleted" and if the dog doesn't exist in the arraylist it should print "the dog couldn't be found".
Everything works perfect until I shall delete a dog that is not first on the list. Then the program shows first "dog was not found" and on the row after "the dog was deleted" if the dog was second on the list. If it was third I will get 2 messages that the dog wasn't found and then that the dog was deleted. I've no clue why it prints both else and if!
public static void taBortHund(){ //Har tar vi bort hund fran listan //System.out.println(hundlista); System.out.print("Vilken hund vill du ta bort? "); String hunden = tangentbord.nextLine(); for (int taBort = 0; taBort<hundlista.size(); taBort++){
ok so for class I'm supposed to Write a class DeleteElements that prints out an array and asks the user which number should be deleted and then deletes that number, if it exists from the array.
The first part tells me to
Step 1 o Start by simply searching the element.
o Pseudocode: -Create an array and populate it with random positive integers. -Print the array to show the user which elements the array contains. -Use a WHILE loop to search the element—a WHILE loop is better than a FOR loop because you can stop when the element is found by using a Boolean value in the loop condition—and also keep track of the location where the element might be found. -If the element is not found, output the error message, “Number not found.” -Otherwise output the message, “Number found at index #.” where # is the index where the element is. -Print out the array.
Example of output: 34 65 12 76 45 39 86 71 67 Number to delete: 76 Number found at index 3
This is what I've got so far but I can't seem to get the "number not found part to print out only once".
public class DeleteElement { public static final int ARR_LENGTH = 10; public static void main(String[] args) { Scanner input = new Scanner(System.in); Random ran = new Random();
[Code] ....
Current output result if value does not exist:
61 89 52 16 20 71 37 91 4 36 Number to delete: 23 Number not found. Number not found. Number not found. Number not found. Number not found. Number not found. Number not found. Number not found. Number not found. Number not found. Current output result if value exists:
97 48 51 22 89 5 42 97 43 96 Number to delete: 89 Number found at index 4
Maybe I'm not understanding the part about the boolean value.
Working on my final which is due today, its' and Inventory Program which I have been working on for the last 5 weeks. My Buttons on my GUI Add/Delete doesn't add items to my inventory. I'm not sure exactly what wrong with my code, I'm not getting any error and the Program compiles just fine, I just can get the Items to add of delete.
my Delete button starts on line 281 my Add Button begins on line 319
// /** Purpose:the purpose of this software is to display inputs as wells as the stocks and price of inputs, *as well as display a 5 % restocking fee per dvd and for the entire Invenotry of each object. *adding a GUI to the code. Adding a Previous button to the existing code allowing the user to cycle through *the Inventory list freely. Also adding a graphics logo to page. adding more buttons and allowing program to *save new items added to the inventory. **/
My method below works fine to print a matrix but when it prints every row, it is printing extra 4 white spaces which is not required. How can I delete those extra spaces at the end? when I use
My current lesson in Java is about ArrayLists and I'm having a tough time to understand this bit of code: This exercise is concerned with the problem of deleting a block of items from an ArrayList.
public static void deleteBlock( ArrayList<String> strings, int n ) { for ( int i = 0; i < n; i++ ) { if ( strings.size() > 0 ) strings.remove( i );

I have a program for a phone directory. It needs to add, delete, append, and edit telephone records. I've gotten it to write and search the files. Just need to get it to delete and edit them.
If my file name is MyBigXMLFile.xml it won't delete but if I rename it to mybigxmlfile.xml it will delete. How do you get around the case sensitive issue?
