Password Rule Using Wrapper Class
Oct 26, 2014
I have to use wrapper class for this assignment. I need to know if my code is more like object oriented or not and am I using the wrapper class properly here? Let me know if I can make this code better.
I also need to know if I can mask this password input (STRING) using NetBeans/Eclipse IDE?
Password rule is as followed : Length of Password 8-12, with no special characters, including minimum one uppercase letter, and only one numeric value.
Java Code:
import java.util.Scanner;
public class Assignment1
{
private static String password=null;
private static void password_input()
[Code] .....

Make a password rule, and take input of the password from the user and compare the password with your rule, if the user had entered valid password then print the message, password valid, else the password is invalid for (the whatever) reason.
Rules:-
-Length 8-12
-Should have one numeric character
-No Special Character
-Atleast one UPPERCASE letter
PHP Code:
import java.util.*;
import java.lang.String;
import java.lang.Character;
public class PasswordSpence {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter a Password: ");
String password = input.next();
if (isValid(password)) {
[Code] ....

My homework is asking me to write a program that prompts the user to enter a password and displays "valid password" if the rule is followed or "invalid password"
Sample
enter a string for password: wewewx
valid password
It's being graded on
Design of my GUI
Dialog box
User friendliness
Creativity
My current issues with the current code I have written is simply the password doesn't work unless it starts with 2 digits, the other order it displays as wrong. and I have no idea how to add a GUI.
import java.util.*;
import java.lang.String;
import java.lang.Character;

I have implemented a deployment rule set for our JRE enterprise deployments and it is working fine. We are currently deploying JRE version 1.8.0_25. I have stumbled upon a Java App (a webcam) on an internet site that I cannot get to run with the deployment rule set.
The rule set works with other java apps, but it’s as though it is ignored for this one. The rule set section in the ruleset.xml with the intention of allowing the webcam to work is as follows:
<rule>
<id location="IP Address of I assume the webcam, address specified in error when launching app" />
<action permission="run" />
</rule>
<rule>
<id location="URL of website hosting the webcam" />
<action permission="run" />
</rule>
I pulled it out of the deployment rule set and added it to the exception list without any luck getting it to work that way. How I can get this app to work with my Deployment Rule Set?

System.out.println("permition granted");

I tried running the code for trapezoidal rule. It's my project in Numerical Methods, here's the code:
static double trapezoidRule (int size, double[] x, double[] y)
{ double sum = 0.0,
increment;
for ( int k = 1; k < size; k++ )
{//Trapezoid rule: 1/2 h * (f0 + f1)
increment = 0.5 * (x[k]-x[k-1]) * (y[k]+y[k-1]);
sum += increment;

It cannot be compiled and I always get FileNotFoundException. I found on Javadocs that this will be thrown when a file with the pathname does not exist.

I have a signed certificate from Entrust which I used to sign a DeploymentRuleSet.xml file. I placed the DeploymentRuleSet.jar in the proper location C:WindowsSunJavaDeployment, afterward the java control panel's security tab shows a link to "show the active deployment rule set" which did not exist prior to coping the file to the directory. When I click on the link a new window opens and says "Rule Set not found" ....

I am new to JAVA GUI programming and was wondering how you go about getting and testing if a password field text equals something. For example, if the password equals "password" then do something.

i need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it

I have a question but dont know how I could verify the criterias..
The password should be at least six characters long
The password should contain at least one uppercase and at least one lowercase letter
The password should have at least on digit
Write a class that verifies that a password meets the stated criteria. Demonstrate the class in a program that allows the user to enter a password and then displays a message indicating whether it is valid or not.
I have not created a class because I really have no clue what to write in this case. My main method is:
import java.util.Scanner; // Needed for the Scanner class
public class Password {
public static void main(String[] args) {
// Create a Scanner object to read input.
Scanner keyboard = new Scanner(System.in);
String input;// To hold the input

System.out.println("LOGIN");
String usernameStr=JOptionPane.showInputDialog("Enter Username");

Also I have to limit password attempts to 3. How would I go about that?

i have this source code...
import java.util.Scanner;
//I had to use scanner in this program because I had to create objects that were in the Scanner class, such as in row 16.
* This program confirms a password typed into a *
* console window *
*/
public class Homework1 {
public static void main(String[] args) {
//Needs to add a scanner to the program to continue on
Scanner keyboard = new Scanner(System.in);

Now I need to create a second version of this program that uses JOptionPane to get the inputs from the user and show the output!

Use Java to write and run a simple console-window program for checking passwords. The program must satisfy the following requirements:
-When the program runs, it should first print its name, e.g., Password Checker
-The program should next prompt the user to enter a username, e.g.,
Please enter your username:
-The program should next prompt the user to enter a password, e.g., Please enter your password:
- If the user enters a correct password, i.e., one that matches an internal secret password, the program responds. You are approved by access control!, and quits.
-If the user enters an incorrect password, the program responds
Try again:
-If the user enters a correct password matching the secret one, the program responds. You are approved by access control!, and quits.
-If the user enters an incorrect password, the program responds
package class1;
import java.util.Scanner;

The goal of this section of my assignment is to ask the user for a password. The password entered has to match the password I set in the code. If it is correct the next dialog box will pop up.
my password is set to:
String enterpwd = "";
String correctPassword = "Setpassword";
I am asked to use JOption, I completed as follows:
enterpwd = JOptionPane.showInputDialog(""............JOptionPane.QUESTION_MESSAGE);
then I use IF statements
if (enterpwd == correctPassword)
xyz = JOption .......();
I am getting an error "java.lang.NumberFormatException: For input string: """
