I need to convert a text file into hexadecimal format and display the hex format and the data offset. I have gotten the conversion to hex to work, but I have been unable to figure out what/how to get the data offset. Here is the code I use to convert the file to hex and display.

public static void displayHex(File file) throws IOException { FileInputStream fis = new FileInputStream(file); int i; byte data[] = new byte[16]; do { i = fis.read(data); for (int j = 0; j out.printf("%02X ", data[j]); } while (i != -1); } 

Here is an image that shows various info, all I need is to display it in text not a GUI and only the Hex and Data Offset.

Note 1: The hexadecimal view displays each byte of the file in hexadecimal; it should look something like this, but simpler:

Note2: The ASCII representation, the Current Offset and the Value Preview are NOT required; also there is no window, no graphics, no colors, just black and white text display. Being a text only display, you are required to display ONLY the Data Offset and the Hexadecimal Representation.
