Java运用HashMap创建一首诗

HashMap储存着一个键值对，我可以用它来创建一个有趣的诗歌。以下是示例代码：

HashMap<String, String> poem = new HashMap<>();
poem.put("sun", "The sun shines bright in the sky");
poem.put("moon", "The moon casts a pale light");
poem.put("stars", "The stars twinkle in the night");
poem.put("ocean", "The ocean's waves crash with might");
poem.put("mountains", "The mountains stand tall and proud");

System.out.println("A Poem:");
System.out.println(poem.get("sun"));
System.out.println(poem.get("moon"));
System.out.println(poem.get("stars"));
System.out.println(poem.get("ocean"));
System.out.println(poem.get("mountains"));

这个程序将会输出以下这首诗：

A Poem:
The sun shines bright in the sky
The moon casts a pale light
The stars twinkle in the night
The ocean's waves crash with might
The mountains stand tall and proud
