为什么我们调用Object.clone（）方法？

Question

This is an implementation of the SinglyLinkedList.clone method given in my book.

public SinglyLinkedList<E> clone(){
    SinglyLinkedList<E> other =(SinglyLinkedList<E>) super.clone();
     // rest of the implementation. 
}

Why we invoked super.clone() .

Answer 1

From the Java API doc of Object.clone(): “this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment”. So I guess the purpose is to create the SinglyLinkedList object that will be the clone.
