枚舉類name()方法 (Enum Class name() method)

• name() method is available in java.lang package.

  name()方法在java.lang包中可用。

• name() method is used to return the name of this enum constants as it is declared in its enum prototype or declaration.

• name() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  name()方法是一個非靜態方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

• name() method is a final method, it does not override in child class.

  name()方法是最終方法，它不會在子類中重寫。
