Introduction

To read a binary file, you usually work with the following classes:

Use the File class to represent the file itself.

FileInputStream connects the input stream to a file.

BufferedInputStream adds buffering to the basic FileInputStream.

DataInputStream reads data from the stream.

The other Stream classes read a byte at a time.

DataInputStream class reads basic data types, including primitive types and strings.

The following code shows how to create a DataInputStream.

Demo Code

                                 
import java.io.BufferedInputStream;
import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

public class Main {
  public static void main(String[] args) throws FileNotFoundException {

    File file = new File("movies.dat");
    DataInputStream in = new DataInputStream(
        new BufferedInputStream(new FileInputStream(file)));
  }//from w w w  .  ja  va  2s.c o  m

}

Or you can do step by step. 

import java.io.BufferedInputStream;
import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

public class Main {
  public static void main(String[] args) throws FileNotFoundException {
    File file = new File("movies.dat");
    FileInputStream fs = new FileInputStream(file);
    BufferedInputStream bs = new BufferedInputStream(fs);
    DataInputStream in = new DataInputStream(bs);
  }

}
