测试数据流和字节数组流的demo

import java.io.*;
import java.util.*;

public class TestDataOutputStream{

    public static void main(String[] args){

        try{
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            DataOutputStream dos = new DataOutputStream(baos);

            dos.writeDouble(Math.random());
            dos.writeBoolean(false);
            dos.flush();

            ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
            DataInputStream dis = new DataInputStream(bais);

            System.out.println(dis.readDouble());
            System.out.println(dis.readBoolean());

            dos.close();
            dis.close();

        } catch(IOException e){
            e.printStackTrace();
        } 

    }

}
