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);

You can do input.next(pattern) to get the next input which matches a certain pattern. If you set this to "." then it will just get the next character entered.
char c = input.next(".").charAt(0);

Scanner scanner = new Scanner(System.in);
char c = scanner.next().charAt(0); //charAt() method returns the character at the specified index in a string. The index of the first character is 0, the second character is 1, and so on.
