Hello Guys, i have some problems with creating some programms wich i need help with.
i need:
A program that finds the tenth letter in the alphabet after the
entered letters. When the letter 'Z' has been reached, it should return to 'A'
to be started.
A program that takes as input the plaintext and a key that the
shift indicates, receives and outputs the ciphertext. A way to deal with punctuation marks and spaces.
A program, for the possibility of decryption, as inputs you need
plus the ciphertext and the key.
From here, you learn computer science. Snap is completely different from java, and is in no way based on it. It's nice to learn snap first, but just so you know, there will be a whole lot more you're going to need to learn in order to learn java, in fact, I'd start now. Use snap to learn about cs, then incorporate stuff you learned from snap into your java programs.

Really, even if we were willing to do your homework for you, you'd be sorry come the exam. And, if you're really interested in learning some computer science, this isn't the way to do it.
originally I think it was smalltalk / sqeak I saw a post jens said something about the only reason its in javascript is so that it can work in the browser (which still amazes me)
to find where letters are in the alphabet, and use 
to deal with wraparound.
