title: Byte[] to InputStream or OutputStream
body: <p>I have a blob column in my database table, for which I have to use <code>byte[]</code> in my Java program as a mapping and to use this data I have to convert it to <code>InputStream</code> or <code>OutputStream</code>. But I don't know what happens internally when I do so. Can anyone briefly explain me what's happening when I do this conversion?</p>
