java泛型数组问题

Question

为什么我这样写老提示 不能创建泛型数组？
Latte, Mocha, Cappuccino，Americano, Breve 均是Coffee的子类
[code="java"]
Class<? extends Coffee>[] types = { Latte.class, Mocha.class, Cappuccino.class,
Americano.class, Breve.class };
[/code]

Answer 1

不支持这么写的..
写成
[code="java"]
// 折中一下, 写成这样
Class<?>[] types0 = { Latte.class, Mocha.class, Cappuccino.class, Americano.class, Breve.class };

Class<? extends Coffee>[] types = ( Class<? extends Coffee>[] )types0;

[/code]
