public class B2016 {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        float x = sc.nextFloat();
        int a;
        a = (int) Math.floor(x);
        System.out.println(a);
    }
}

把 float x = sc.nextFloat(); 给成 double r1 = scanner.nextDouble(); int a改成long a; a = (int) Math.floor(x) 改成 a = (long) Math.floor(x);
