将十进制值从表格打印到CSV文件

Question

//使用FileWriter导出为CSV的Java代码。

Java Code :

FileWriter fileWriterForCsv;
fileWriterForCsv.append(4.500);
fileWriterForCsv.append(",");
fileWriterForCsv.append("Mani");
fileWriterForCsv.append(",");
fileWriterForCsv.append("March");

//导出的CSV文件的内容如下所述     生成的CSV     ______________

Actual Result : 4.5,Mani,March

Expected Result : 4.500,Mani,March

Please let me know whether i need to change the java code??  or how to proceed to get the expected result as above mentioned

还尝试将列类型更改为CSV模板中的文本。没有得到预期的结果。

Answer 1

尝试格式化数字输出。这应该在最后用CRLF写出整行。

fileWriterForCsv.format("%.3f,%s,%s%n", 4.5, "Mani", "March");
