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 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 want to validate an email input. The email input can only have one @ and at least one '.' after the @. I would like to ask if my regex pattern is correct.
YOUR CODE HERE import java.util.InputMismatchException; import java.util.Scanner; public class email { public static void main(String []args) {

I am trying to create a program that first asks the user for an input in the form: condition = value, where condition is a word from the set {limit, deficient, abundant, perfect, prime}, and value is a positive integer. Then it verifies the input. If the input is invalid it prints a message indicating that and terminates. If the input is valid it prints a table with the number of abundant, deficient, perfect and prime numbers less than or equal to N, where N = 1, 2, 3, ..., limit.
My problem is with the input validation. i want it to read the value as a string and verify if it's integer.
Here is my code
import java.util.Scanner; public class Factors { public static void main (String[] args) { Scanner scan = new Scanner(System.in); int n, f, fsum, p=0, a=0, d=0,pe=0,limit=0,abundant=0, deficient=0; System.out.print("Enter stoping condition (condition = value): "); String cond = scan.next();
When input validation for the first months rainfall is non-negative, this results in correct average rainfall.
When input validation is used for the first months rainfall I'm prompted to input a positive number, which is 2.
When asked to input rainfall, in inches, for each month, I begin with input -3, I am again prompted to re-enter a positive, I enter 3. What happens is, whichever positive integer I input after I had entered a negative for the first months rainfall, the average would be off by the positive number inputted.
package averagerainfall; import java.util.Scanner; public class AverageRainfall { public static void main(String[] args) { int maxYears; int totalMonths;
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.
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>
How do you do validation in java for primary key lets say the table got combination of two columns as primary key,how can i validate that if use enter already existing value...
I am trying to validate the phone number with a method called isValidAddress and whenever it gets to that line of code in the while loop I get a lot of red line java exceptions. I am referring to lines 130-138
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).
How to use validation on a label or textfield in java.

import java.util.Scanner; public class PassCode { public static final String SPECIAL_CHARACTERS = "$,#"; public static void main(String[] args)

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.
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;

I have a Registration Form in which I am registering user to perform some sort like Entering messages I want to perform some Server Side validation.
Like suppose a user has Enter an Id then as soon as he start entering the Id then I want that this Id should be checked in database that if this Id exists in database or not.
and similar types of validation I want to apply on other fields to.
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))
