import java.util.Scanner; // 注意类名必须为 Main, 不要有任何 package xxx 信息 public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); String x = in.nextLine(); String[] result = x.split(","); long b = Long.parseLong(result[3]); long a = Integer.parseInt(result[1]); long out = b - a -1; System.out.print(out); } }
注:应使用Long.parseLong()避免NumberFormatException问题
