编程题A+B和C，求大神解决我的问题！！！

今天刷编程题遇到一个坎，题目是A+B和C，我用的是Java，自己在IDEA上编译运行没有问题，但是牛客网上它一直无法通过，报空指针异常，我怀疑是我用了字符流造成的，但是不明白为什么，求大神指教
代码附上

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        Scanner sc = new Scanner(System.in);
        int count = sc.nextInt();
        String line;
        int a;
        int b;
        int c;
        boolean[] booleans = new boolean[count];
        for (int i = 0; i < count; i++) {
            line = br.readLine();
            a = Integer.valueOf(line.split(" ")[0]);
            b = Integer.valueOf(line.split(" ")[1]);
            c = Integer.valueOf(line.split(" ")[2]);
            booleans[i] = (a + b > c);
        }
        for (int i = 0; i < count; i++) {
            System.out.println("Case #" + (i + 1) + ": " + booleans[i]);
        }
        br.close();
    }
}
