使用DataOutputStream将双精度写入文件

import java.io.DataOutputStream;

import java.io.FileOutputStream;

import java.io.IOException;/** 来自 N o w  J a v a  . c o m**/

 

public class Main {

 

  public static void main(String[] args) {

   

    String strFilePath = "C://Folder//WriteDouble.txt";

   

    try{

      FileOutputStream fos = new FileOutputStream(strFilePath);

      DataOutputStream dos = new DataOutputStream(fos);

      double d = 165;

      dos.writeDouble(d);

      dos.close();       

    }
