Hi,

On page 554 question 6, is it really correct to say "Line 7 creates the Hello class with the generic type Object since no type is specified"? I ask this because the compiler can infer that the type T is String because of the parameter passed to the constructor.

Thanks,
Guillaume

Guillaume,
You're right. It's not. All three of these compile. Some with warnings, but they still compile.

Three years later, I'm going through the errata in detail to fix them for the Java 11 book. (We are further along than it appears. I did my harder chapters first.)

It turns out this was not an errata. The generic parameter isn't used here. So even though it is in a class with a generic parameter, that doesn't apply to the new object.
