Please advise me about calculating length

Dear all,

I am converting a file which is encoded as ASN.1/BER. While I converting that file almost of it goes fine. But some record length is more than 256 is confusing problem. Java byte is not unsigned, so its values are -127...0 ... 127. I can calculate length that is lower than 256.

How can I calculate length that is more than 256.

Thank you,
