How do I something like this in Java
class TreeNode<Item<K,V>> {
}
The code above does not compile.
You have to declare K
and V
to be generic parameters and you have to declare the name of the type parameter you want bound to Item<K, V>
. Assuming that Item
is a predefined generic type, you can do something like this, for instance:
class TreeNode<K, V, X extends Item<K, V>> {
...
}
Or perhaps (and more likely) you don't need a separate type parameter X
and just need to declare K
and V
as type parameters:
class TreeNode<K, V> {
private Item<K, V> mItem;
...
}
