Swing/AWT/SWT :: Mobile Number Validation?
Apr 6, 2014
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 have to validate security number based on tHIS REQUEST
If the SECURITYNNUBER IS INVALID UNDER THE SECURITYNUMBER attribute,it must reject(Date & algorith). To override the normal validation,the subject must contain INVALIDSECURITYNUMBER. The incorrect ID number must still reflect in the SECURITYNUMBER attribute.
THE FIRST 6 DIGIT IS DATE
EXAMPLE 7701205334086
public boolean val_SECURITYNUMBER()
{
boolean flag = true;
String u_Securtynr = transactionFile.getS_securtynumber();
// 1. Invalid securty number if completed
if(!isBlank(u_Securtynr))

I have a question with this gui project I am building, I have gotten the code to work in very basic forms such as the main part of calculations and etc. But now I am in the phase of validation to make sure the textboxes aren't empty and are in the correct format. I have done alot research already. I would like to use a Joptionpane to warn the user of an invalid entry. But I have tried many different methods and I can't seem to get them to work.
private void calculateActionPerformed(java.awt.event.ActionEvent evt) {
double loanAmt;
int years;
boolean validData;
double rate,total,calcRate,payment,amount,numMonths,totalPayment,paymentRounded,numMonthsRounded;
[Code] .....
When ran I get these errors: (only copied a few of the main lines)
Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "p"
at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1241)

The code below is just the GUI for a slot machine. Currently when play is clicked it displays the random number, I'm trying to make it so each random number displays an image in the GUI instead. For example if the random numbers were 2,2,3 it would display Cherry, Cherry, Bells. I started changing field1 to the image but realised I was on the wrong track as it would just display the same image not one allocated to a number. I've left in what I started doing.
how to do it?
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SlotMachineGUI {
JPanel mainPanel;
SlotMachine slotEngine;

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 have a number of cells which are Dates and need to have them appear in the same format. The samples I have seen usually create a new cell renderer object for each cell, even if its the same type. Since I have a number of Date cells I thought it best to use a single object for each of the date cells, but after seeing the different samples I am wondering if there is something I may be missing where using the same cell renderer object could potentially be an issue.

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".

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.

2. Given the size of the data and input being xml, how should i approach this problem(considering the rules might change etc)

Following is the structure of the xml :

</Fields>
<Childs>

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;

In my web application (jsf 2.2 + prime 5), when I click the submit button, JSF says: "validation error". I think the problem is related to my equals method contract.
Debugging the equals method, the type received by this method is "Short" (my PK type) and not the object type to compare (professional type in this case). So, equals will return false always!
PK declaration in Entity Class
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
private Short id;
equals method:
public boolean equals(Object obj) {
if (obj == null) {
return false;
[Code] ....
Is this correct?
