Java – converts files into byte arrays in reverse order

byte[] bFile = new byte[(int) file.length()];

FileInputStream fileInputStream = new FileInputStream(file);
fileInputStream.read(bFile);
fileInputStream.close();

This code lets me convert the file into a byte array, and I want to read the file from beginning to end (in reverse order)

Edit: I won't read the end of the whole file (about 1000 bytes, for example)

resolvent:

File file = new File(/*file path*/);
byte[] bFile = new byte[1000];

RandomAccessFile fileInputStream = new RandomAccessFile(file, "r");
fileInputStream.seek(fileInputStream.length() - bFile[0].length);
fileInputStream.read(bFile, 0, bFile.length);
fileInputStream.close();

I just figured out that I read the last 1000 bytes of the file
