读取任何文件作为二进制字符串 [英] Read any file as a binary string

问题描述

正如标题所暗示的，有没有什么办法来读取一个给定文件的二进制重新presentation（txt文件，.DOCX，.EXE等）在Java中（或任何其他语言）<？ / p>

在Java中，我知道如何读取文件的内容是，即：

 串线;
BR的BufferedReader =新的BufferedReader（新的FileReader（myfile.txt的））;
而（（行= br.readLine（））！= NULL）{
    的System.out.println（线）;
}
 

但我不知道（如果可能的话）来读取文件本身的二进制重新presentation。

解决方案

 文件文件=新的文件（文件路径）;
字节[]字节=新字节[（INT）file.length（）];
DataInputStream以DataInputStream所=新DataInputStream所（新的BufferedInputStream（新的FileInputStream（文件路径）））;
dataInputStream.readFully（字节）;
dataInputStream.close（）;
 

字节是一个字节数组的所有文件的数据在它

As the title suggests, is there any way to read a binary representation of a given file (.txt, .docx, .exe, etc...) in Java (or any other language)?

In java, I know how to read the content of a file as is, i.e:

String line;
BufferedReader br = new BufferedReader(new FileReader("myFile.txt"));
while ((line = br.readLine()) != null) {
    System.out.println(line);
}

But I'm not sure (if it's possible) to read a binary representation of the file itself.

解决方案

File file = new File(filePath);
byte[] bytes = new byte[(int)file.length()];
DataInputStream dataInputStream = new DataInputStream(new BufferedInputStream(new FileInputStream(filePath)));
dataInputStream.readFully(bytes);           
dataInputStream.close();

bytes is a byte array with all of the data of the file in it
