While loops

Question

I’m suppose to be doing a while loop/try/catch statements In My confusing final project that is creating an authentication system with the user being able to try 3 times before being forced to exit. While also using a MD5 hash. And we haven’t even gone over MD5 yet. Any help would be appreciated, because I’m stuck at the whole loop/try catch part

Answer 1

I wanted y’all to know I got a B on that final :)

Answer 2

You forgot to mention the language. And did you try anything and failed or don't know how to start?

Answer 3

Good job!

Answer 4

I've sent the eclipse project file to you.

I know everyone has it's own way of codding.... but I hope it's helpful.( at least the comments should be)

btw : the valid passwords are 'java' / 'code' / 'Destiny' / and of course 'Farshaad'. ;)

Answer 5

hey I don't know if that's the problem.
but after coping ur code in eclipse I found some problems.
the first one was that u r missing on curlybrace at the end of the code (for "FinalProject" class)
then the other thing was that u don't increment the "atempts" variable ,cussing an infinite loop even if the text file couldn't be found.

The file didn't download properly. When I opened it, it stated that it contained binary code and if I wanted to open it. When I opened it it was "s¼8áW8|œÙ

Answer 9

I apologize its Java. I have the beginning on my computer because it’s a good way through the program. I’m confused on how to put user credentials into a while statement

Answer 10

I didn't use Java a lot yet, but it seems like the same question was asked on stackoverflow

https://stackoverflow.com/questions/39809924/how-do-i-use-md5-to-convert-passwords-and-check-a-users-credentials-against-val

There is a solution in the comments, but make sure you understand what's going on and not just copy the code.

Answer 14

In all honesty I got a lot of the code from my professor and I had to fill in where the comments are. His part of the code is putting in the file, and I’m not sure how to reference it or make it read it. When I get home from work I’m going to have to try more things but I’ve been working on this for a week and can’t get any farther
