Question

I have a question about Java Generics. If I define a class like this:

public Test<String> ...

Does this mean that my class now acts like a collection type for Strings? For example when seeing it like this List I know that it is a List of Strings. Does the <> always mean it’s a collection (general meaning, not the actual Collection type)?

thanks,

No. It just means that your type is parameterized with the type String. There are plenty of non-collection generic types. See Callable<T>, Future<T>, Comparator<T> for example.
