ArrayList Features - Implement Password Strength Checker
Jun 18, 2014
Iv created an array list which contains people and attributes such as user id, username etc. It works fine for the most part. It allows the user to enter a name into the system. If the name entered matches a name stored in the array list then it will display that user, its id, name and password. I need to implement a password strength checker; but i am struggling.
First off; i need a method that will determine how strong a password is. I then need to find a means of how to output the result of this, outputting it alongside the other outputted attributes: id, name and password.
Here is what i have attempted so far, but to be honest its probably completely different to the exact strength check and way that i want the result to be displayed. I know that the code below is a good start, but its not close to implementing the code in a way that the password strength result can be outputted in the arraylist after a search for a user and their password is made.
private int checkPasswordStrength2(String passw)
{
int strengthCount=0;
String[] partialRegexChecks = { ".*[a-z]+.*", // lower
".*[A-Z]+.*", // upper
".*[d]+.*", // digits
".*[@#$%]+.*" // symbols
};
if (passw.matches(partialRegexChecks[0])) {
[Code] .....
I just really want to get this done. Iv looked for solutions online; but they implement a password strength checker much differently to how mine needs to work from what i can tell.
I am developing a number of Data Structures in Bluej. Iv created a nice little arraylist program, and want to add a password generator to this program. People are already prestored within the arraylist, and contain attributes such as ID, name, password, etc. I can search a persons name within the list and then view their ID, password, and encrypted password. I want to add a field which will show password strength, bare in mind the password is already stored within the program and will not be entered via the user.
I understand that this could be done via a regular expression, or using some count method where certain goals/sets of characters increase the count which determine strength.
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);
[code]....
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; public class class1 { public static void main(String[] args) { // TODO Auto-generated method stub
I am trying to write a password checker program and thats the error i get. (the final error!) but this one i dont know how to fix. here is my code.
/* Text Text text */
import java.util.Scanner; // Imports the Scanner class to get Keyboard Inputs class PriceRichardChapter5Test { public static void main (String [] args) { String Password; // Creates the Password variable

Write a program that determines the number of Dots in an input line. Read in the line into a string. Next use the charAt( ) method in a loop to access the characters one by one.
Your program should have comments towards the top of the program. Copy at least two sample runs and paste as a comment at the bottom of the program. At least one sample run would be a string that has a few blanks. At least one sample run would be a string that does not have any blanks.
Use Assign5_{your last name} as the name of the program.
Submit one file, the Java file only.

I'm doubted regarding the implementation of Collections.binarySearch() method on an ArrayList of objects of a custom class Movie.
Here is the movie class :
public class Movie implements Comparable<Movie> { String movieName; String rating; String director; String theme;
[Code] .....
The sort/binarySearch in searchByMovieName function is done with natural sorting (and Comparable Interface in Movie class). I mean no comparators involved here. And the comparator that I used for sorting/binarySearching on Movies Director attribute in searchByMovieDirector function is :
public class MovieDirectorComparator implements Comparator<Movie> { public int compare(Movie movie1, Movie movie2) { return movie1.getDirector().compareToIgnoreCase(movie2.getDirector()); } }
But I was not able to implement binarySearch ?? How to implement the binarySearch here. I have google to see only binarySearch working on Arrays or probably ArrayList of String only, but not on ArrayList of custom objects.
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.
I have a checker game already and I am trying to make an AI opponent even if not so Intelligent as long as it can move chips on its own until the game is over.
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 can't get the code to compile for the driver every time i get an error message saying
SudokuCheckerTest.java:28: error: cannot find symbol foo.displayGrid(grid); ^ symbol: variable grid location: class SudokuCheckerTest SudokuCheckerTest.java:29: error: cannot find symbol foo.getGrid(grid);
[Code] .....
4 errors
Java Code :
import java.util.Scanner; public class SudokuChecker{ public SudokuChecker(){ // displays intro code and initializes the array grid as well as using method calls. Scanner in = new Scanner(System.in); int [][] grid = new int [4][4]; displayGrid(grid);
I'm trying to make a checkers game in Java and I managed to make my grid with it's button on it. Each button which has a pawn on it has it's own actionListener which was all done in the loop as I made the grid as shown in my code below. Now I have a huge problem. I don't know how to handle the move, check if move is legal, jump and double jump. Here is the code I wrote so far. I wrote it in such a way that all the buttons which have a pawn on them can perform the same action but then I'm completely stuck.
import java.awt.event.*; import javax.swing.*; import java.awt.*; public class CheckerBoard extends JPanel{ public static final int WIDTH = 530; public static final int HEIGHT = 530; private JButton[][] grids;
Why, when I write a right password and nickname, program says that is wrong?
public class Password { private static String password = "1234"; private static String nick = "artem"; public static void main (String args[]){ JFrame frame = new JFrame("Password"); JPanel pan = new JPanel(); JLabel lab = new JLabel("Password"); JLabel lb1 = new JLabel("Nickname");
I want to validate username and password in JavaScript. I want to validate username and password with database values. If login failed i want to display alert message...ok. But problem is that i have index.jsp page. After clicking login button control goes to homepage.
jsp..okk.. in index.jsp I have taken dropdown to show designation. I select design then control goes to respective homepage... in homepage. I am checking username and password with database values. If login successful it goes to respective pages but if login failed it has to show me alert message. How can i do that ?
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 one query regarding OTP, In my project while registration the otp should be generate and send to the mobile number of user which is registered the form.
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
When I enter the wrong password, it says I have successfully logged in.
import javax.swing.JOptionPane; public class P2H { public static void main (String[] args) { System.out.println("LOGIN"); String usernameStr=JOptionPane.showInputDialog("Enter Username");
[Code] ....
Also I have to limit password attempts to 3. How would I go about that?
I've made a login system with a username and a password. The password is visible and I wanna hide it, how do I do that? Here is my code (have used swing);
