Hi,
I have been able to parse the data file. But I have one question regarding the 2 byte flag that indicates whether the record is valid or deleted. I am not able interpret correctly:
The flag is 2 bytes. If it is deleted record, then it will be stored as 0x8000 (per the assignment). But how can 2 bytes (that is the size of the flag) store 0x8000.

thanks,
Jayprakash

0x8000 is 1000 0000 0000 0000 in binary. That's 16 bits (a short in Java terms).

Getting someone to think and try something out is much more useful than just telling them the answer.

2 byte can hold 0xFFFF or 2^16 whats equals to a java short as Barry said
