The program contains username and password which on submission checks with the database if the details entered are right or wrong....on right details it Displays Welcome (name) and (lastname) parameters from database.
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.
I am getting errors when I try setting left and right values (which are String types) for my tree.I tried doing something like:
Node node = new Node("Is it human?", null, null); node.getLeft().setNode("Is it Zelda?");//the first left Q node.getRight().setNode("Is it Kirby?");//the first right Q
but that gives me a runtime error of "java.lang.NullPointerException" which points to the line 2. I also tried this:
Node node = new Node("Is it human?", null, null); node.setLeft(setNode("Is it Zelda?"));//the first left Q node.setRight(setNode("Is it Kirby?"));//the first right Q
but that gives me another error, pointing to the setNode for both lines 2 and 3,plus it wouldnt make sense since both setLeft and setRight takes in Node types, not String types.
Here is my Node class:
public class Node { private Node leftPt, rightPt;//left and right pointers for Node private String node, left, right; public Node(String node, Node leftPt, Node rightPt){ this.node = node; this.leftPt = leftPt; this.rightPt = rightPt;
I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().
My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.
I trying to make a file browser but when i try to add item to a FlowPane through me an error at runtime, look at this code if i add label with imageView when there are more than x ítem the error appear.
But if i add the label and the imageView alone the error didn't show. Ihave folder in my pc with more than 1200 file and the error always appear. Is there a way to make a flowpane or tilepane hold enough items?
I'm trying to access class file which is inside the package and package is inside the jar file but I can't access that class file inside my source file . All files are on desktop .
I have an issue with variables/attributes scope inside a jsp tag file.
In short, I have a tag with an attribute named "id". If the page using my tag has a variable called "id" (maybe coming from the spring model) and I call my tag WITHOUT specifying the id attribute, inside my tag I still can acces to the "id" attribute that was defined in the page but I don't want this behavior; if the tag is called without the "id" attribute then it should defaults to empty/null.
(...) The id is: ${id} // <- Prints 'X' <my:print /> <- Prints 'X' ! I want it to not print anything in that case <my:print id="Y"/> <- Prints 'Y' (...)
What I want is to have the tag attributes live only in the tag, without having any knowledge of any variable outside of the tag itself. Is it possible?
My current workaround is to remove the "id" attribute, enable dynamic attributes and with a scriptlet search in the dynamic attributes map for the "id" and save it in a variable with a different name (e.g. "__id").
We have an application running successfully where we fetch the weight of product currently on Production Line using Java.
All the products on line belong to same order and are of same type. User at beginning enter the type of product and starts the production line.
Proposed new process: Now client want that multiple type of product can belong to same production order. i.e. on a production line different type of products can come one after other. So we should now fetch the type of product also.
The Question : what are different possibilities in which we can find the type of product. Can java fetch color of a box ? If we use scanner on line that scans the product and sends the color information to Java.
Above is just a possibility. Can there be any other parameters that Java can use to differentiate in type of product ?
Currently we are clueless. What ever are the possibilities in Java we can propose the same to client. Even if that requires additional hardware.
I have a source code here that counts the frequency of alphabetic characters and non-alphabetic characters (see the source code below).
import java.io.*;
public class letterfrequency { public static void main (String [] args) throws IOException { File file1 = new File ("letternumberfrequency.txt"); BufferedReader in = new BufferedReader (new FileReader (file1));
[Code] ....
But, let's just say that now I have the following characters in the text file, "letternumberfrequency.txt": 71 geese - 83 cars - 58 cows- 64 mooses- 100 ants- 69 bangles- 90 molehills - 87 noses
The numbers inside that text file would be considered as strings, am I right? But I want to extract the numbers so that I can also be able to count their frequency - not as individual digits but as whole numbers (that is how many "71", "83", "58", "64", etc. are there...). Would using "Double.parseDouble ()" work?
I need to read a csv file from the disk and manipulate the data inside. My problem is that if the csv (excel format) contains "" in any of it's values the whole string line gets saved/displayed incorrectly . For example for the line in the csv file :
If I change the servlet and have "request.getRequestDispatcher("/pages/ViewCompletedWWDocs.jsp").forward(request, response);" un commented, I get exception "java.lang.IllegalStateException: Cannot forward a response that is already committed".
I know that the simple deployment using only applet tags inside HTML causes severe security restriction for the applet on the client side. but can this simple HTML file contains .jar files inside the applet tags instead of .class files.
I am developing my college's project in JSP using jquery to open a magnific popup when user clicks on a link and the in the magnific Popup must be fetched from Mysql and i tried two approaches for this:
1. magnific Popup type is ajax here i passed the variable value in the link of href (after '?') to another JSP page where connection to database is created and queries are written in JSTL to fetch data and show this in magnific Popup .. But i failed in this approach, don't know in another JSP page the data without having database connection is loaded in the magnific Popup easily but not database data..
2. magnific Popup type inline here i need to pass the variable value in the same page between different tags..
I have an assignment on sorting, i kno i can get the sorting down but im having an issue with inputing the 512 ints in a file into an array. the instructor provided us with a file with 4 equal sets of ints. i tried to make my array of size [scan.nextInt()] and it cuts off the last 21 ints. and skips the first int. how can i get all of the integers in the text file into my array? this is what i have so far. if i hard code the array to size 50000 and then try to print the array it compiles but errors out when running it.
System.out.println("Please Enter text file in this format, XXXXX.txt :"); String file =fileName.nextLine(); Scanner scan = new Scanner(new File(file)); int [] data = new int[scan.nextInt()]; <-------here it skips first int int count= data.length; for (int i=0; i<data.length-1;i++) { data[i]=scan.nextInt(); } System.out.print(Arrays.toString(data));
rst 4 ints in output are: 501, 257, 390, 478...., supposed to be 492,501,390....and last ints are: ....88, 83, 79, 0 and supposed to be :88 83 79 77 76 72 71 71 66 57 56 48 48 41 33 30 23 23 18 17 15 13 9....it replace last ints with 0. why ? and how do i fix this. attached it the text file
I'm having an issue, I have a scanner (Scan.nextLine();) that scans the console for input to fetch the string "word". Then I want to fetch a character using Scan.findInLine(word).charAt(number);. The problem is that the console requires me to write 2 lines in order for the program to move on. I only want the program to scan for a word, and then move on with what it has instead of requiring 2 inputs.
I have to fetch only the book name attribute and use it for display .However say for example ,I have got the list of Books ie(C#,Oracle,Archius) ,passing this value to a method should return me an array of URL nodes value within it.
The idea is to display the book names in a list and then on user selection , corresponding URL needs to be fetched.
Was able to get the loop for traversing the nodes
[java=code] NodeList nodeList = document.getDocumentElement().getElementsByTagName ("Book"); for (int i = 0; i < nodeList.getLength(); i++) {... [java=code]
So
a) Display the BookNames
b) Get the corresponding URL's for the particular book if I pass the Bookname
