Can anyone provide an example of how this would be used? (checkExistChar)

Create a boolean method called checkExistChar(char input,char[] array). This method returns true if the given array has the input in one of the indexes (check for duplicates) Otherwise return false

It's used in a hangman game, if that helps.

This is obviously an assignment.

Show us your attempt and we will guide you but we won't do this for you.
