Arrays og generics

HashMap[] hm = new HashMap[5];
        hm[0] = new HashMap<String,String>();

compiler

HashMap<String,String>[] ghm = new HashMap[5];
        ghm[0] = new HashMap<String,String>();

compiler med en warning

->arne_v: Ja, men
hm[0].put("key","value");
- giver så warning i dit første eks.

jep

->arne_v: Jeg søgte selv lidt rundt og fandt:
http://weblogs.java.net/blog/arnold/archive/2005/06/generics_consid_1.html
("Generics are a mistake")
http://www.angelikalanger.com/Articles/Papers/JavaGenerics/ArraysInJavaGenerics.htm
("Since this is an inevitable side effect of the translation by erasure, it might make sense to ban arrays of type variables from Java Generics")

I mit tilfælde vil jeg bruge ArrayList i stedet for array, tror jeg.

->arne_v: Smid gerne et svar.
