Java.util.Collection重写spliterator（）

Question

In the source code of Collection<E> , I am wondering why the @Override annotation is used. The spliterator() method doesn't come from Iterable<E> , and Object doesn't have it either.

public interface Collection<E> extends Iterable<E> {
    @Override
    default java.util.Spliterator<E> spliterator() {
        return java.util.Spliterators.spliterator(this, 0);
    }

Answer 1

Iterable DOES HAVE spliterator. Check javadoc for java8 not the previous ones
