如何使用 opencsv 将整数值写入 csv 文件

Question

这是我编写 csv 文件的代码

CSVWriter writer = new CSVWriter(new FileWriter("test.csv",false));
String [] details = new String[]{"00000002","0","0","0","0","type_detils","01","1","-1","0.0","0.0","CST"};
writer.writeNext(details);

我想把这个值格式写成csv：

00000002,0,0,0,0,"type_detils",01,1,-1,0.0,0.0,"CST"

但是当我查看文件时，它是这样的：

"00000002","0","0","0","0","type_detils","01","1","-1","0.0","0.0","CST"

如何在使用 opencsv 写入文件期间将字符串值更改为整数？

Answer 1

您可以像这样尝试 3 参数构造函数 (link)：

CSVWriter writer = new CSVWriter(new FileWriter("test.csv",false),',','\0');

使用 '\0' 是空字符。或者，如果 CSVWriter 接受它，则可能传递 null。
