java strings：指向“字符串s = new s = new String（“ silly”）”

問題1：為什麼使用“必要的新caseinsensitivestring（...）”的用法是“必要的？”

Question 2: Adapting CaseInsensitiveString to behave like String

While the default behavior of CaseInsensitiveString necessitates the use of its constructor, there are potential avenues to mimic the simplified syntax of the built-in String class.

With Extension:

Extending String would allow CaseInsensitiveString to inherit its behavior.

Overriding the static factory method of String would enable direct instantiation from literals.

However, this approach tightly couples caseinsensitivestivesting to string類，限制其靈活性並引入潛在的維護問題。 沒有擴展：

在“ valueof（...）”方法中，使用傳遞的文字將創建caseinsensitivestring的新實例。
