大疆软件A卷的第二题，请问什么叫输入多组数据？？？

用java编的，请问什么叫输入多组数据，这个多组怎么界定？？while(true)死循环吗？？？？
一个输入把我搞死了，，，，，测试用例都是对的，，通过率是0，，，我特么。。

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    String line1 = scanner.nextLine();
    String str[] = line1.split("\\s+");
    int lcount = Integer.valueOf(str[0]); //零食种类，即行数
    int money = Integer.valueOf(str[1]); //总钱数
    int sumnums = 0;
    Listlistv = new LinkedList();
    Listlistp = new LinkedList();
    listv.add(0);
    listp.add(0);
    for (int i = 0; i < lcount; i++) {
        String line2 = scanner.nextLine();
        String arr[] = line2.split("\\s+");
        int value = Integer.valueOf(arr[0]);
        int manyil = Integer.valueOf(arr[1]);
        int nums = Integer.valueOf(arr[2]);
        sumnums = sumnums + nums;
        for (int k = 0; k < nums; k++) {
            listv.add(value);
            listp.add(manyil);
        }
    }
    int dp[][] = new int[sumnums + 1][money + 1]; //物品数量、总钱数
    int v[] = new int[listv.size()];
    for (int i = 0; i < v.length; i++) {
        v[i] = listv.get(i);
    }
    int p[] = new int[listp.size()];
    for (int i = 0; i < p.length; i++) {
        p[i] = listp.get(i);
    }
            //        int v[] = {0,26,26,26,26,5,5,5,5,5,5};//价格
            //        int p[] = {0,100,100,100,100,1,1,1,1,2,2};//满意度
    for (int i = 1; i < dp.length; i++) {
        for (int j = 1; j < dp[0].length; j++) {
             if (j < v[i]) {
                 dp[i][j] = dp[i - 1][j];
                  continue;
              }
              int v1 = dp[i - 1][j - v[i]] + p[i];
              int v2 = dp[i - 1][j];
              dp[i][j] = v1 > v2 ? v1 : v2;
         }
     }
    System.out.println(dp[sumnums][money]);
 }
