需求:这是一个杂乱无章的文本文件,大约有1M左右,现在需要从"",""后面开始换行,并且去掉后面的逗号
格式如些"00000000001 ",1,"21-4-8-1","J288","1",4,491441.78999999998,3306097.5589999999,,1,0.88,,1,3,"",""

哥们 不行啊 我的QQ是313463133 咱们QQ聊啊 请教下啊

Answer 3

public static void main(String[] args) throws Exception {
FileInputStream fis = new FileInputStream("e:/file.txt");//输入文件
StringBuffer temp = new StringBuffer();
byte[] buffer = new byte[1024];
int pos = 0;
while((pos = fis.read(buffer)) != -1){
temp.append(new String(buffer,0,pos));
}
fis.close();
String tar = temp.toString();
FileOutputStream fos = new FileOutputStream("e:/result.txt");//输出文件
fos.write(tar.replaceAll("\"\",\"\",", "\r\n").getBytes());
fos.close();
  }快洗洗睡吧.

Answer 4

oh,看错结果了.倒数第二行改一下.
fos.write(tar.replaceAll("\"\",\"\",", "\"\",\"\"\r\n").getBytes());
