java - 如何使用文本文件中的数据创建 DefaultTableModel

Question

我有这个测试文件 text_file我的 TableView 是 enter image description here我想将每一行与每一列相匹配(第一行-第一列，第二行-第二列，等等。)错误在哪里？

        BufferedReader infile = new BufferedReader(reader);
        String line = "";
        int counter = 0;
        String title = "";
        String author = "";
        String price = "";
        try {
            while ((line  = infile.readLine()) != null) {
                ++counter;

                if (counter == 1) {
                    title = line;
                } else if (counter == 2) {
                    author = line;
                } else if (counter == 3) {
                    price = line;
                    SimpleBook sb = new SimpleBook(title, author, price);
                    bookList.add(sb);
                    counter = 0;
                }
            }
        } catch (IOException ex) {
            Logger.getLogger(SimpleBookList.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

}

    public class SimpleBookList {

    private ArrayList<SimpleBook> bookList;

    public SimpleBookList() {
        bookList = new ArrayList<SimpleBook>();
    }

    public void add(SimpleBook sb) {
        bookList.add(sb);
    }

    public ArrayList<SimpleBook> getBooks() {
        return bookList;
    }

    public void readFromTxt(String filename) {
        File file = new File(filename);
        FileReader reader = null;
        try {
            reader = new FileReader(file);
        } catch (FileNotFoundException e) {
            System.exit(1);
        }
        BufferedReader infile = new BufferedReader(reader);
        String line = "";
        int counter = 0;
        String title = "";
        String author = "";
        String price = "";
        try {
            while ((line  = infile.readLine()) != null) {
                ++counter;
                if (counter == 1) {
                    title = line;
                } else if (counter == 2) {
                    author = line;
                } else if (counter == 3) {
                    price = line;
                    SimpleBook sb = new SimpleBook(title, author, price);
                    bookList.add(sb);
                    counter = 0;
                }
            }
        } catch (IOException ex) {
            Logger.getLogger(SimpleBookList.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
