Question

我是Java语言的新手。是否有任何方法可以读取文件，直到某个字符再次循环。示例文本文件将如下所示。

    No.    Title     Score
    1       abc        9
    Info: adajiodasjdsajkldas adhq sdahdu
    dasjkdajkldsa adwq
    dasjlkda qe quei qoep
    No.    Title     Score
    2       abc        9
    No.    Title     Score
    3       abc        9
    Info: dasjkdaj aks
    dasjlkda
    No.    Title     Score
    4       abc        9
    Info: dasjkdaj dahjkqi
    dasjlkda

我需要的是阅读开头，直到得分和其余部分将被忽略并让它读完后再重新制作一个新循环。这是我如何编码这个，我不知道如何消除/读取信息，直到新的号码同时信息可以是多行或它可能是空的这是我编码但未完成的方式，我正在寻求帮助以使其完整。

    Scanner read = new Scanner (new File("Student.txt"));
    read.useDelimiter("[\\s]+");
    String Eliminate[] = new String[99];
        String No[] = new String[100];
        String Title[] = new String[100];
        String Score[] = new String[3];
        int i =0;
    while (read.hasNext())
    {   
            Eliminate[i] = read.nextLine(); //eliminate first line
            No[i] = read.next();
            Title[i] = read.next();
            Score[i] = read.next();

            System.out.println(Eliminate[i] + "\n" + No[i] + " " + Title[i] + " " + Score[i] + "\n" ); // just for debugging
            i++;
        }
        read.close();

这个怎么样？

while (read.hasNext())
{   
    if (read.next().equals("No.")){
        Eliminate[i] = read.nextLine(); //eliminate first line
        No[i] = read.next();
        Title[i] = read.next();
        Score[i] = read.next();

        System.out.println(Eliminate[i] + "\n" + No[i] + " " + Title[i] + " " + Score[i] + "\n" ); // just for debugging
        i++;
    }
}
