FileReader 跳过 CSV 逗号分隔文件中的每一行

Question

为什么此代码在只有 3 列的 CSV sheet 中每隔一行跳过一次？

public void loadFile(String fileName) {
    try (BufferedReader csvReader = new BufferedReader(new FileReader("C:\src\" + fileName + "", StandardCharsets.ISO_8859_1))) {

        while (csvReader.readLine() != null) {

            String[] data = csvReader.readLine().split(",", 3);
            String sku = data[0];
            String title = data[1];
            double price = Double.parseDouble(data[2]);
            Product newProduct = new Product(sku, title, price);
            newProduct.setProducts(newProduct);
        }

    } catch (IOException e) {
        System.out.println("Could not load file: " + e.getMessage());
    }
}

每次调用 readLine，它都会读取一行并移动到下一行。您需要存储读取的行。

String line;
while ((line = csvReader.readLine()) != null) {
    String[] data = line.split(",", 3);
    // ...
}
