Data Validation Of XML File
Mar 23, 2015
I have an xml file whose data needs to be validated with 250+ rules, the size of the xml can range from 4MB to 50 MB. Have the following questions.
1. Where the Rules should be defined, as i would like them to dynamically controlled(instead of hard coding)
2. Given the size of the data and input being xml, how should i approach this problem(considering the rules might change etc)
3.The names of the UI and XML tag names will be different, so when should the translation takes place
Following is the structure of the xml :
<DATA>
<Parent>
<Fields>
//All the data like name, age, height, weight, blood group etc goes here
</Fields>
<Childs>
<Name = 'Andrew' id = 7560>
[Code] ....

By using FileReader, FileWriter and their constituents, I am creating a file to contain employee information ( name, age, hours, etc. ). The user is to input all of the data on a single line and we were asked to implement StringTokenizer to assign that data to the file. I have never used the StringTokenizer before, but I have a rough idea how it is to function. I used pw.println to test what I have so far, now I would like to let the user build the initial file with the "first employees" of the company, and then view the file, and then go back and append new employee data to that same file. My question is, how can I take the user input as a StringTokenizer and add that to the file?
In the for loop below, I thought I would see if it would work, but it does not. The loop only executes once and does not allow me to enter data.
public class Records {
public static void main(String [] args) throws IOException {
Scanner input = new Scanner(System.in);
FileWriter fw = new FileWriter("dbs3.java");
BufferedWriter bw = new BufferedWriter(fw);
PrintWriter pw = new PrintWriter(bw);
System.out.println("NEW EMPLOYEE DATA SHEET");
System.out.print("Number of new employees: ");
int number = input.nextInt();

I am trying to remove a line based on user input. myFile.txt looks like:
Matt
Brian
John
However when I enter "Brian" (to remove this line), It is deleted on the temp file (myTempFile.txt), but not renamed back to the original file (myFile).
import java.io.BufferedReader;
import java.io.BufferedWriter;

I am creating a program where it reads the data inside a file and then places this data into arrays. The file I created has numbers 1-30 in it, file named, testing1.txt .
Java Code:
public static void main(String[] args) {
// TODO Auto-generated method stub
// Variables Declaration Section
//******************************
BufferedReader br;
String sCurrentLine;
String str;
[Code] ....
My issue is that the 'str' value is not initialized, but if I initialize it, it ruins the code. I'm not sure what to do in the situation.

New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file,
(2) The original list of N numbers printed in reverse order of how they appear
in the input file.
(3) The sum and average of these numbers,
(4) The minimum of all the numbers,
(5) The maximum of all the numbers.

I have a small application that I have been working on for several months. It works great. Now when I created an executable .jar file for it, it will not load data from a .csv file. I have tried looking into everything I can think if. I checked file paths, etc. I am using OpenCVS to read the csv. Is there an issue with that when you include it into another .jar file? I am trying to log if there is an error but I don't even get an error. I just doesn't run past that statement...

I need to write an input validation while using the do-while statement. I feel like most of it is good except that it gets stuck inside the brackets of the do statement. After I enter an input, it just keeps asking me over and over for an input. Then I have to make it s if you enter an input that is out of range, you have to keep entering an input until it is in range.
Java Code:
do
{
System.out.print("Please enter the amount of spaces the letters will shift... ");
shift = uInput.nextInt();
} mh_sh_highlight_all('java'); Java Code: public class ShiftEncoderDecoderDriver
{
public static void main(String[] args)

I want to add validation to some of the elements in my constructor.
Person(String idIn, String nameIn, ) {
this.id = idIn;
this.name = nameIn;
}
I want to be able to check that the data for the ID is limited to a certain collection of characters formatted in a certain. For example, I may wish to limit it to 5 lowercase letters or numbers, or a combination of both. How could I do this?

I have a JSF page for changing login credentials and i preferred to use Java validations instead of JSF validations on the inputText. The password validation works fine but the username validation does not produce any output. This is my JSF form
HTML Code:
<h:form>
<p><strong>Please type your new username: </strong>
<h:inputText size="15" value="#{register.newUsername}"/></p>
<p><strong>Please type new your password: </strong>
<h:inputSecret size="15" value="#{register.newPassword}" /></p>
<p><strong>Please retype new your password: </strong>

I have a GUI that prompts the user for information. When they click 'submit', a new customer gets created from a class like so ...
Java Code:
public void actionPerformed(ActionEvent arg0) {
Customer customer = new Customer(); // New customer object
customer.name = view.getName();
customer.age = Integer.parseInt(view.getAge());
customer.ccn = view.getCCNumber(); mh_sh_highlight_all('java');
I am having difficulties validating my variables for nulls. For instance ...
Java Code:
// METHOD TO RETRIEVE TEXTBOX INPUT -- NAME
public String getName() {
String name = null;
if (jtfFirstName.getText() == null || jtfLastName.getText() == null || !jtfFirstName.getText().matches("[a-zA-Z]+") || jtfLastName.getText().matches("[a-zA-Z]+")){ // Validate name fields
JOptionPane.showMessageDialog(null, "<html><i>Improper Input Detected.</i>
[code]...
I can't seem to win with this. Whether the fields are filled in properly or not, I get the error message and the program continues to completion using the name "null".

if (TxtMobile.getText().length() < 11) {
rooms.setVisible(false);
JOptionPane.showMessageDialog(getRootPane(), "Mobile number should be 11 numbers long", "Mobile Error", JOptionPane.ERROR_MESSAGE);
TxtMobile.requestFocus();
}
else if (TxtMobile.getText().length() == 11) {
rooms.setVisible(true);
}
No compilation errors but code doesnt seem to be working. IF mobile number input is less than 11 numbers an error message dialog appears to alert the user then is supposed to focus on the text box in question. But instead after clicking the ok on the dialog box, the next rooms form shows up even though ive set that to setVisible(false).

I am very new to Java. I have been working for a couple months on a program for school. It has not gone well. I finally was able to scrap together a working program, but i left something out that needs to be. I have to include input validation to check for negative values, prompting users to re-enter values if negative. I have included my current code, the program works perfectly, but what to do about the negative numbers.
Java Code:
package gradplanner;
import java.util.Scanner;
public class GradPlanner {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int numofclasses = 0;
int totalCUs = 0;

I'm having trouble with the code using char[]c, for the special characters. Every thing else seems to work correctly, expect for the special characters.
