java - 使用 CsvBeanReader 时有没有办法跳过标题？

Question

我有一个项目，我应该将对象写入 CSV 文件。我目前正在使用 ICsvBeanWriter，但每次传递新记录时，它也会写入 header 。从文件读取时会产生问题。

下面分别是读取和写入的方法:

    public static ArrayList<communication> readCSV() throws IOException {
    ArrayList<communication> fileText = new ArrayList<>();
    ICsvBeanReader beanReader = new CsvBeanReader(new FileReader("products.csv"), CsvPreference.STANDARD_PREFERENCE);
    String[] header = beanReader.getHeader(true);
    CellProcessor[] processors = new CellProcessor[]{
            new ParseDouble(), // Distance
            new ParseDouble(), // Efficiency
            new ParseDouble(),// fuel
            new ParseDouble(),// total
    };
    communication com;
        while ((com = beanReader.read(communication.class, header, processors)) != null) {
                fileText.addAll(Collections.singletonList(com));
        }
    return fileText;
}

public static void writeCSV(double tripDistance, double fuelEfficiency, double costOfFuel, double totalCost) throws Exception {

    // create a list of employee
    List<communication> EmployeeList = new ArrayList<>();
    EmployeeList.add(new communication(tripDistance, fuelEfficiency, costOfFuel, (Math.round(totalCost * 100.0) / 100.0)));

    ICsvBeanWriter beanWriter = new CsvBeanWriter(new FileWriter("products.csv",true),
            CsvPreference.STANDARD_PREFERENCE);

    String[] header = new String[]{"TripDistance", "FuelEfficiency", "FuelCost", "Total"};

    beanWriter.writeHeader(header);
    CellProcessor[] processors = new CellProcessor[]{
            new ParseDouble(), // Distance
            new ParseDouble(), // Efficiency
            new ParseDouble(),// fuel
            new ParseDouble(),// total

    };

    for (communication com : EmployeeList) {
        beanWriter.write(com, header, processors);
    }
    beanWriter.close();
}

我想要一种跳过写入或读取标题的方法，或者创建删除所有标题行(跳过第一行)的方法。

这是出现的错误:

org.supercsv.exception.SuperCsvCellProcessorException: 'TripDistance' could not be parsed as a Double
processor=org.supercsv.cellprocessor.ParseDouble

这些代码行创建一个 header :

String[] header = new String[]{"TripDistance", "FuelEfficiency", "FuelCost", "Total"};
beanWriter.writeHeader(header);

我想你可以从代码中删除它们。
