when I check how to work the Clone in http://www.cafeaulait.org/course/week4/46.html
it explains that clones are doing shallow copy. If I need deep copy, I will need to override
In this case, if I want to perform deep copy for a Map<String, AObj>, do I need to go all the way down into the fields of AObj?
By the way, when I do:
String b = "abc"
String a = b,
is it doing deep copy or shallow copy?
