Generics are implemented by erasure. This means that they enforce their type constraints only at compile time and discard (or erase) their element type information at runtime. By contrast, array types are [...], so they can enforce their type at runtime (e.g. if you try to store a String into an array of Long, you’ll get an ArrayStoreException).
