从具有意外输出的文件中读取

Question

import java.io.DataInputStream;
import java.io.FileOutputStream;
import java.io.FileInputStream;
import java.io.InputStream;


class Myclass
{
    public static void main(String args[])
    {
        try{
                //writing data into file from byte stream i.e FileOutputStream and  reading from DataInputStream    
                int data[]={99,76,65,55,99};
                FileOutputStream fout=new FileOutputStream("C:\Users\dell\Desktop\testingfile.txt");

                for(int i:data)
                {
                    fout.write(i);
                }
            Myclass m=new Myclass();
            FileInputStream fin=new FileInputStream("C:\Users\dell\Desktop\testingfile.txt");
            m.readMethod(fin);
            }catch(Exception e)
            {
                System.out.println("Exception caught");
            }
    }

 void readMethod(InputStream obj)
  {
    try{
        DataInputStream din=new DataInputStream(obj);//noe datainputstream has only one constructor with parameter of Inputstream
        int d;
        while((d=din.readInt())!=-1)
        {
            System.out.println(d);
        }
    }catch(Exception E){}

  }

I am writing set of integers to the file testingfile.txt with the write(int) method available in FileOutPutStream.I have created a method readMethod which reads Integer from file with method available in DataInputStream.But reading from an file gives me different output.It differs from data i have written.Why is my Output different?Can anyone correct my code or tell me why is that so?
Output is :1665941815.

Answer 1

void write(int b)
Writes the specified byte to this file output stream.

在JavaSE文档(http://docs.oracle.com/javase/8/docs/api/java/io/FileOutputStream.html)中，write方法用于写入一个byte，而不是int，即使它接收一个int值作为参数。

也许您需要改用 DataOutputStream。
