Take a char input from the Scanner
You could take the first character from Scanner.next:
char c = reader.next().charAt(0);To consume exactly one character you could use:
char c = reader.findInLine(".").charAt(0);To consume strictly one character you could use:
char c = reader.next(".").charAt(0);
Setup scanner:
reader.useDelimiter("");After this reader.next() will return a single-character string.
There is no API method to get a character from the Scanner. You should get the String using scanner.next() and invoke String.charAt(0) method on the returned String.
Scanner reader = new Scanner(System.in);char c = reader.next().charAt(0);Just to be safe with whitespaces you could also first call trim() on the string to remove any whitespaces.
Scanner reader = new Scanner(System.in);char c = reader.next().trim().charAt(0);
