Java - input scanned character-by-character?

Question

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:
https://docs.oracle.com/javase/7/docs/api/java/lang/String.html

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

"I though I'd try doing it myself, since I like a challenge."
"I have not tried anything yet."

Do you see an anomaly there?

My friend told me this literally 20 minutes ago, and I'm still at college. I'm planning on starting when I get home. The only reason I put that in, is because it wouldn't let me leave it blank and it needed at least 30 characters.

So why did you post this question in the first place? You say you are going to try it yourself, so go and try it first and see what problems you come up against. Then when you have a specific question people will try to help you.

This is a problem. When I said "I'll try it myself" I meant the whole program. This question is about a problem I've realised before even attempting to do the code.

If you are saying that you do not understand how to process a string character by character then I do not see how you are going to succeed with the more advanced parts of the program. you also need to understand that the problem is to convert Morse code to English not the other way round.

Since you like challenges, what prevents you from finding the solution?
