左面是对的。

翻了翻 JDK 官方仓库的提交记录,没找到右面的出处。


找了找这本书的原版,英文版中就是这样写的,那就不是中译本的问题了:

For example, in Java 8 you can now call the sort method directly on a List. This is made possible with the following default method in the Java 8 List interface, which calls the static method Collections.sort:

default void sort(Comparator<? super E> c) {

Collections.sort(this, c);

}
