package com.machuang.io.others;

import java.io.BufferedOutputStream;
import java.io.DataOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class DataStream {

    public static void main(String[] args) throws IOException {
        writeBasicTypes("F:/win10/test/data.txt");

    }

    public static void writeBasicTypes(String desPath) throws IOException {
        // 要写出的数据
        double dataDou = 3.6;
        long numL = 100L;
        String dataStr = "architecture";

        // 关联写出的文件
        DataOutputStream dos = new DataOutputStream(
                                    new BufferedOutputStream(new FileOutputStream(desPath))
                                                                                            );
        dos.writeDouble(dataDou);
        dos.writeLong(numL);
        dos.writeUTF(dataStr);

        dos.flush();
        dos.close();
