How to add character from JOptionPane to an array and prevent duplicate entries

dewwolf

How would I go about adding letters placed inside the pane to an array so that it saves for printing? (pseudocode)

String x; x= JOptionPane.showInputDialog(null, "letter entry"); char y= x.charAt(0);

So it takes x and turns it to a char, but how would I add the letters inputted into an array? It takes one letter at a time, so new letters would be added as each input is accepted.

Also, how would I be able to prevent duplicates in this? Say the user entered "a" and tried to enter "a" again, it would create an error dialogue and ask for a different letter. Thanks in advance :)

I ended up just using String xxx+= y (as per the above example).

Is there a way to prevent duplicates in this way? I'd like entries to be singular and not repeat.

@GoToLoop what's the difference between https://github.com/aerrity/Inputs and https://github.com/GoToLoop/Inputs? In fact, the former seems to be ahead of your one.

@Lord_of_the_Galaxy, that link @kfrajer's posted is merely a fork I did of its original repo! ^#(^
And hence, it's just a screenshot of the moment it was forked, frozen forever in time! :!!

Then it would be wiser to post a link of the original.

Most of my examples includes various links in their header already: :-c

How can I tell it was not the latest version? I didn't pay attention to the version but then, I didn't know there were multiple repos.

@kfrajer, in order to send fixes to a GitHub repo, we need to create a fork of it, which is a screenshot of its current state. :-B

For latest versions, we need to go to the original repository, not to its forks. =;

Also, when starring some repo, make sure it's the original 1 instead of its many forks. ;;)

How can I tell @GoToLoop?

There's a book icon at the left side of the original repo's name:
https://GitHub.com/aerrity/Inputs

And for forked repos, at the same spot as it was the book icon, it shows this strange icon instead:
https://GitHub.com/GoToLoop/Inputs

Thanks @GoToLoop. Right below the fork icon, I can join the main repo.
