New to Java

Hi all,

I am trying to add two numbers represented as strings, i.e., addition of two hexadecimal numbers. I am aware of the addition process where we convert the strings to number format (int / long) and add these two and convert the result back to Hex.

I do not want to use this process due to limitations in precision of int and long data-types. Is there any other way of adding these hex numbers? My line of thought forces me to consider the following process:

A)Hex to Binary ;
B)Binary Addition ;
C)Binary Result to Hex

Will this work or am I wrong?

All inputs are appreciated!!

Cheers,
