Remove the first char at the string str[0]
Then after removing str[0] is a real char

You can just make a nextLine() call after the nextInt() call and before the nextLine() in which you actually accept input. This will take in up to the '\n' char left behind by the call to nextInt().
Scanner scan = new Scanner (System.in);
int i = scan.nextInt();
scan.nextLine();
char t = scan.nextLine().charAt(0);
Or you can just use nextLine() to get your int as well and convert it to an int
Scanner scan = new Scanner (System.in);
int i = Integer.parseInt(scan.nextLine());
char t = scan.nextLine().charAt(0);
