你如何在Java中创建一个字典？
我正在尝试实现一本字典（如实体书）。我有一个单词列表及其含义。
I am trying to implement a dictionary (as in the physical book). I have a list of words and their meanings.
Java提供哪些数据结构/类型，用于将单词列表及其含义存储为键/值对。
What data structure / type does Java provide to store a list of words and their meanings as key/value pairs.
如果给出一个键，我可以找到并返回值吗？
How, given a key, can I find and return the value?
您将需要一个 Map< String，String> 。实施 地图的类界面包括（但不限于）：
You'll want a Map<String, String>. Classes that implement the Map interface include (but are not limited to):
HashMapLinkedHashMapHashtable
每个都是针对某些情况设计/优化的（请访问他们各自的文档以获取更多信息）。 HashMap 可能是最常见的;
Each is designed/optimized for certain situations (go to their respective docs for more info). HashMap is probably the most common; the go-to default.
例如（使用 HashMap ）：
Map<String, String> map = new HashMap<String, String>();
map.put("dog", "type of animal");
System.out.println(map.get("dog"));
type of animal
