HI all
I am referring to the EJBDesignPatterns book and I see hexFormat() method in there that has 8 as second argument. Now to convert the int to hex format we can use Integer.hexString() method right? THen I don't understand why the algorithm in the book has 8 as an argument?
Does anybody know?
Thanks
Maulin
