Reads some number of bytes from the input stream and stores them into the buffer array b.

Usage

From source file:Main.java

private static byte[] readFully(InputStream input) throws IOException {
    byte[] buffer = new byte[8192];
    int bytesRead;

        output.write(buffer, 0, bytesRead);
    }/*  ww w . jav  a 2s  . c o m*/
    return output.toByteArray();
}
