My friend just told me he needs to write a code that translates Morse code to English, and he's really struggling (his teacher showed them the interface for the program, but didn't actually give them the source code for it, which I find really stupid, since you can't really make a program, without making some reference to interface elements such as button and checkboxes). I though I'd try doing it myself, since I like a challenge.

Anyway, so I want the input of the user to be checked character-by-character, which means if someone puts in "Hi", the code won't check for "Hi", but instead for "h" and "i" separately, and then display the Morse code equivalent for both. (upper and lower case don't matter much. Right now, I just want to get the translation down)

How would I do this?

What I have tried:

I have not tried anything yet.

That doesn't really point me into anything. You gave me a link to the main tutorial site, how am I supposed to find what I need to learn?

You go through the tutorials and learn. We can't teach you programming over the internet and we won't do your or your friends homework for them either.

That is the real life of a programmer:
To find what you need (if you did not know it already).

So, if you did not know Java, that link is the starting point.

If you did know Java, think about the problem.
In your case like:
Ok, I have a string and want to process each character in it. Where do I get information?

Answer: Read (or know) Java strings:

So how do I get the single characters from the string?
Solution: Read the above link. There might be functions doing exactly that.

"I have not tried anything yet."

Do you see an anomaly there?

Ask Google these questions:
1. split string to character java
2. upper lower case character java
3. case switch java
