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);

我想在csv中写这个值格式：

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？

的文件写入期间将字符串值更改为整数

Answer 1

您可以尝试这样的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。
