迭代方法实现链表的定义

public class MyListItr implements Iterable {

private class Node {

public Type data;

public Node pre;

public Node next;

public Node(){}

public Node(Type d, Node p, Node n){}

}

private Node Header;

private Node Tail;

private int theSize;

public MyListItr(){}

public void add(Type item){}

public void print(){}

public int size(){}

@Override

public Iterator iterator() {}

private class MyListIterator implements Iterator {

@Override

public boolean hasNext() {}

@Override

public Type next() {}

@Override

public void remove() {}

}

}
