复制代码代码如下:

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

import java.io.InputStreamReader;

public class csv{

public static void main(String[] args) throws IOException {

File outfile = new File("D://new_car.csv");//存储到新文件的路径

try {

InputStreamReader isr = new InputStreamReader(new FileInputStream("D://car.csv"));//待处理数据的文件路径

BufferedReader reader = new BufferedReader(isr);

BufferedWriter bw = new BufferedWriter(new FileWriter(outfile));

String line = null;

while((line=reader.readLine())!=null){

String item[] = line.split(",");

/*

*信息处理块

*/

bw.newLine();//新起一行

bw.write(""+","+"");//写到新文件中

}

bw.close();

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}
