Depending on how it is used, in some cases, one will compile and the other will generate a compile error. In other cases, the other will compile, and the first one will generate a compile error.

Hi Wong,

Thanks for the help.



In the above program <E extends Number>
Does it includes Number and its subtypes or just the subtypes of Number?

Thanks

Bounded generic types are inclusive -- so in the example E can have a type of Number.
