Password Generator

Generate a list of unique passwords. Your program should prompt the user for how many passwords they want to generate, then print the list of passwords. All passwords should follow this pattern:

Begin with a random four-letter word. The starter code includes a static method to return a list of valid words.

One special character: ! @ # _ . * The starter code includes a static method to return an array of the special characters.

A two-digit number: 00-99

Five random alphabetic or numeric characters from: abcdefghijklmnopqrstuvwyxzABCDEFGHIJKLMNOPQRSTUVEWXYZ0123456789. The starter code includes a method to return these characters as a String

The password rain_23A6vW9 is an example that meets these rules. Your program must include code that checks to see that all passwords are unique.

Complete the Java program PasswordGenerator, which is in the attached zip file. Implement the following methods:

main

Complete the code in the main method so that the program prompts for the number of passwords, then creates and prints the specified number of unique passwords. Refer to the Sample Output below.

createPassword

Complete the method public static String createPassword(). This method should return a password that meets the rules outlined above. Note that the starter code contains static methods to create four-letter words, special characters, and alphabetic/numeric characters.

isPasswordUnique

Write the method isPasswordUnique(). This method should take 2 parameters: the password to check and a String containing all unique passwords created so far. Return true if the password is unique.

addUniquePassword

Complete the method public static String addUniquePassword(String aPassword, String passwordList). This method will return an updated String containing all unique passwords including aPassword.

Notes:

Hint: The starter code contains 140 unique four-letter words

Hint: You can track the already-generated passwords in a String. Each time you create a new password, you can update the String of already-generated passwords

Items in the program that you must complete have a TODO comment

EX: // TODO: Complete this method

Assume that the user only enters valid input

Complete this program in baby steps. There are many ways to approach this program, but whichever order you use, write something then test it immediately. For example, write one method and test it. Then write another and test it. And so on. It is better to have something that works, though its incomplete, than to have something complete that has nothing working.

Grading Elements:

Generated passwords meet the specified rules

Generated passwords use the four-letter words, special characters, and password characters static methods provided in the starter code

All passwords are unique

Specified number of passwords are created

Previously generated passwords are tracked efficiently

Provided method signatures are not changed

Any new methods have appropriate signatures
