如何从文件中填充对象数组

Question

在这里，我试图通过使用BufferedReader来填充我的对象数组。问题是，我得到了一个错误，指出数组在1处超出了索引

此外，文件中的每个标记都由一个空格分隔，这样我就可以在字符串数组中拆分标记，并在属性上进行拆分

public class BooksReader {

    static book arbook[] = new book[14];

    public static void array_filler() throws FileNotFoundException {

        String Line = "";
        try {
            BufferedReader br = new BufferedReader(new FileReader("MyPath"));

            while ((Line = br.readLine()) != null) {

                int i = 0;

                String ar[] = Line.split(" ");
//The attributes of each object are two strings and 3 integers
                arbook[i] = new book(ar[0], ar[1], Integer.parseInt(ar[2]),    Integer.parseInt(ar[3]), Integer.parseInt(ar[4]));
                i++;
               
            }

        } catch (IOException ex) {
            Logger.getLogger(BooksReader.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

    public static void main(String[] args) throws FileNotFoundException {
        BooksReader.array_filler();
    }
}

那么有人能帮我写代码吗？或者甚至建议另一种方法？

你需要移动inti=0 while循环之前的几行，因为它现在的工作方式，您将始终尝试访问arbook[0]
