Bill share errors

This program reads a bill in whole dollars, then the number of people sharing it, and prints each person's share, rounded down. In Java it runs inside a main method, with Scanner imported.

bill = int(input())
people = int(input())
share = bill // people
print("Each pays " + str(share))

Scanner in = new Scanner(System.in);
int bill =
    Integer.parseInt(in.nextLine());
int people =
    Integer.parseInt(in.nextLine());
int share = bill / people;
System.out.println(
    "Each pays " + share);
