java byte stream array
0 Answer(s) 3 years and 2 months ago
Posted in : Java Beginners

I have a byte array that contains hexadecimal data for eg
byte[] testMessage = {0x02, // STX
0x31,0x32,0x10,0x02,0x33, // Data 31 32 02 33
0x03, // ETX
0x31^0x32^0x02^0x33^0x03}; // LRC calculated from the data (with the DLE removed) plus the ETX

i have to find the position of stx,etx and report if the message is a valid message as per some specified protocols.

I just wanted to know that in order to navigate through this byte array do i need to convert the hexadecimal values in any other number system and how should i navigate through the array.

please help
thanks in advance
