Answer 2

What is the purpose of opening it?
To run (if it's an exe) or to read it (or part of it)?
If you are such a beginner, then I advise you to read something on the topic, this elementary question is described in many textbooks. For example, there is a command
BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
buf.read(bytes, 0, bytes.length);
buf.close();
Or like this, simpler: byte bytes[] = FileUtils.readFileToByteArray(file);
