Answer 1

If table column is having not null constraint, 
then a property related to that column in generated class will be of primitive type. 

If table column is not having not null constraint, 
then a property related to that column in generated class will be of java.lang.X type. 
(X == any of Integer,Byte,Float,Double depends on table column type in database) 

If table column is having primary key constraint, 
then a property related to that column in generated class will be of primitive type. 

If table column is having primary key constraint and it is AUTO INCREAMENT OR foreign key, 
then a property related to that column in generated class will be of java.lang.X type. 
(X == any of Integer,Byte,Float,Double depends on table column type in database)
