Well it seems the other programmers in some other sections have been creating password generators in different languages, so I thought I would take a swing at it and make something simple out of it. I may improve it or work off some of your ideas.

Anyhow, its a simple GUI that has 3 textfields, which creates/writes to a Passwords.txt file. I may make it load in XML just for the fun of it later.

Virus scan if you wish, but its clean. Smile
Thanks.

Yeah, we have been making a bunch of password generators Big Grin

But I have a question: Does it actually generate passwords? Because I see there is a text field for "Desired Password". Or is it just a utility that can save your user name and password in case you forget them?

Good job, though. It makes a nice, simple project.

Thanks for the comment, unfortunately I havnt got to the random generations yet, but I will add it very soon. So for now, its a utility.

Right. Thanks for the confirmation.

Done version 2 I guess, trying to figure out character randomization, and for now im using the Random API for randomizing the numbers. According to the results, the amount of numbers being randomized depend on the desired passwords input. So thats a bug fix needed.

Soon to add XML.

Nice job. It looks promising.

Maybe adjust the layout of the buttons and text fields a bit?

Think about it... what's a simple way of having numbers correspond to any element? If you guessed array, you're right.

You could set up an array of 26 characters, and then initialize them with a for loop. shouldn't take more than three lines of code.

Code:
char letters[26];
for(int i = 0; i < 26; i++) {
     letter[i] =(char) i + 97; //ascii key codes, 'a' is 97.
}

the iffy part here is the type-casting, I think java allows casting from an int to a char (I mean, why wouldn't they), but if not, I'm sure there's a method for turning an int into a char.

from there, you can get random characters by using pseudorandom elements in the array.

i.e...
Code:
char nextChar = letters[Random_generator.nextInt(25)]; //probably wrong syntax, but you know what I mean...
password.append(letter);

Uhm thanks? But im pretty sure I have the mental capacity to figure it out. ;)
Also, I have to figure out that Number randomization, I will get to it when I have time.

Once I go through this tutorial I'm walking myself through right now, hopefully I'll be able to make GUI's like this... idk D:
