java - 遍历二叉搜索树

Question

我想用 Java 浏览字典中的每一项。为了澄清我想要做什么，这是 C# 代码:

Dictionary<string, Label> LableList = new Dictionary<string, Label>();
foreach (KeyValuePair<string, Label> z in LabelList) { … }

Answer 1

temp += ("<" + it.next() + ", " + bstd.getValue(it.next()) + ">");

每个 hasNext() 调用 next 两次。将下一个值存储在局部变量中。

Object current = it.next();
temp += ("<" + current + ", " + bstd.getValue(current) + ">");
