//將使用FileWriter以CSV格式導出的Java代碼。

Java Code : 

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

//導出CSV文件的下面 提到的內容而生成CSV ______________

Actual Result : 4.5,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 

也試圖改變列的類型，如CSV模板文本。沒有得到預期的結果。

嘗試格式化數字輸出。這應該在最後用CRLF寫全行。

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