Question

我有一个csv文件，我在其中将数据库查询到一个csv文件。但是由于某些原因，数据不准确。正如您在步骤_1列的“我的结果”下图中所看到的，数据看起来很准确，但是需要将$ 4转移到步骤_2列中。有什么办法可以帮助我用下面的代码解决这个问题？谢谢

如果需要将数字作为格式字符串，则需要引用所有包含逗号的字符串。

// Takes some value and coverts it to a quoted string. 
String getQuotedCell(Object o){ 
    StringBuilder sb = new StringBuilder("\"");
    sb.append(o).append("\",");
    return sb.toString();
}

此处示例Repl.it

我建议您虽然只输出数字值而不是字符串。电子表格程序可以很容易地将数字格式化为美元金额。

有点像这样。

while (rs.next()) {
    StringBuilder sb = new StringBuilder(); 
    for (int i =1; i <= 26; i++) {
       sb.append(rs.getObject(i)).append(",")
    }
    sb.append("\n");
    writer.write(sb.toString()); // write row.
