Usage

From source file:Hex.java

    }
    try {

        InputStream in = new FileInputStream(args[1]);
        int len = 0;
        byte buf[] = new byte[1024];
        while ((len = in.read(buf)) > 0)
            os.write(buf, 0, len);
        in.close();

        }

        FileOutputStream fos = new FileOutputStream(args[2]);
        fos.write(data);
        fos.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
