Thanks everyone.
Dick the SCJP is an exam designed by people at Sun Microsystems to
test you're understanding of the Java programming language and if the study guide is anything to go by some of the questions require you be "on yer toes".
Although this is not directly CattleDrive related it is slightly relevant partly because our friendly sherrif, and Chief Nitpicker Marilyn is mentioned inside the front cover of my study guide and thanked for her contribution, so when (if) I pass, the nitpickers will have played a part in more ways than one, so thanks in advance
