java - 将 BinarySearchTree 条目导出到列表

Question

请注意，BinarySearchTree 类来自 net.datastructures 5.0

   public static <K, V extends Comparable> List<Entry<K, V>> sortTree(BinarySearchTree<K, V> tree) 
    {   
        List<Entry<K, V>> entries = new ArrayList<Entry<K, V>>(tree.size()); 
        entries.addAll(tree.entries());

我将如何解决这个问题？

 Error: The method addAll(Collection<? extends Entry<K,V>>) in the type List<Entry<K,V>> is not applicable for the arguments (Iterable<Entry<K,V>>)

Answer 1

for(Entry<K,V> entry : tree.entries()) { entries.add(entry);}
