Have a base genric class like ClassBase<T>
I found I can use
ClassDerived extends ClassBase
or
ClassDerived<T> extends Classbase<T>
So basically it means I can remove generics in the derived class, is that right?
Since all generic type information is erased in the compilation process, of course you can do that. However, most compilers will generate a warning unless the warning is turned off or suppressed. For instance, if I write
class Foo extends HashMap {}, Eclipse reports: “HashMap is a raw type. References to generic type HashMap should be parameterized”
