Wildcards also have the advantage that they can be used outside of method signatures, as the types of fields, local variables and arrays. We can maintain the history in a static variable inside class Shape, and have drawAll() store its incoming argument into the history field.

Wildcards are designed to support flexible subtyping, which is what we're trying to express here. It will generally infer the most specific type argument that will make the call type-correct.

If a generic method appears inside a generic class, it's a good idea to avoid using the same names for the type parameters of the method and class, to avoid confusion.

Here is an example. static void fromArrayToCollection(T[] a, Collection c) { for (T o : a) { c.add(o); // Correct } } We can call this method with any kind of collection whose element It is possible to use both generic methods and wildcards in tandem. The signature of copy expresses the dependency using a type parameter, but uses a wildcard for the element type of the second parameter.

Here's a first attempt: static void fromArrayToCollection(Object[] a, Collection c) { for (Object o : a) { c.add(o); // compile-time error } } By now, you will have learned to avoid Why was the identity of the Half-Blood Prince important to the story? So the element type of src can be any subtype of T—we don't care which. One question that arises is: when should I use generic methods, and when should I use wildcard types?

Returning to our shape drawing problem, suppose we want to keep a history of drawing requests. We could have written the signature for this method another way, without using wildcards at all: class Collections { public static void copy(List dest, List src) { Please try the request again. Any object copied from the source list, src, must be assignable to the element type T of the destination list, dst.
