Why doesn't Java allow for the creaton of generic arrays?
- by byte
There are plenty of questions on stackoverflow from people who have attempted to create an array of generics like so:
ArrayList<Foo>[] poo = new ArrayList<Foo>[5];
And the answer of course is that the Java specification doesn't allow you to declare an array of generics.
My question however is why ? What is the technical reason underlying this restriction in the java language or java vm? It's a technical curiosity I've always wondered about.
