Java将CSV文件读入数组但忽略第一行

Question

我已经编写了以下代码，但是我需要跳过第一行，因为它是字段名称。我这里的文件是 cart.csv。当代码读取第一行时，我会收到错误。

购物车.csv

Number,Item,Quantity
1,Book,10
2,Fruit,14
3,Toy,2

代码

 try {

            br = new BufferedReader(new FileReader(file));
            while ((line = br.readLine()) != null) {

                // use comma as separator
                String[] data = line.split(",");

                String sql = "INSERT INTO DB (Number,Item,Quantity) values (?, ?, ?)";
                pstmt = conn.prepareStatement(sql);
                pstmt.setString(1, data[0]);
                pstmt.setString(2, data[1]);
                pstmt.setString(3, data[2]);
                pstmt.executeUpdate();
                System.out.println("Upload Completed");
    }

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (SQLException ex) {
            Logger.getLogger(POI.class.getName()).log(Level.SEVERE, null, ex);
        }

在 while 循环之前添加一个 readLine() 以跳过第一行。

br = new BufferedReader(new FileReader(file));
br.readLine(); //read the first line and throw it away
while ((line = br.readLine()) != null) {
