[weixin_44754630]

这个具体怎么实现啊，各位大佬

[qq_39936465]

public class test16 {

	public static void main(String[] args) {
		String str,s[];
		try {
			FileReader f1=new FileReader("test.dat"); //路径请配置相应的路径
			FileOutputStream f2=new FileOutputStream("result.txt");//路径请配置相应的路径
			BufferedReader bfr=new BufferedReader(f1);
			DataOutputStream dos=new DataOutputStream(f2);
			while((str=bfr.readLine())!=null) {
				 str=str.replace("\r\n", "");
				 s=str.split(",");
				 dos.writeShort(s[0].length());
				 dos.writeChar(',');
				 dos.writeChars(s[0]);
				 dos.writeChar(',');
				 dos.writeShort(s[1].length());
				 dos.writeChar(',');
				 dos.writeChars(s[1]);
				 dos.writeChar(',');
				 dos.writeShort(Short.parseShort(s[2]));
				 dos.writeBytes("\r\n");
			}
			bfr.close();
			f1.close();
			dos.close();
			f2.close();
		} catch (NumberFormatException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
