關鍵字是預定義的保留字, 在語言中具有特殊含義。 不能將其用作標識符。
但在 kotlin, 有一些關鍵字在某些情況下可以用作標識符。 在 kotlin 中基本上有四種類型的關鍵字:
1.硬關鍵字 2.軟關鍵字 3.修飾符關鍵字 4.特殊標識符
Keywords are predefined, reserved words that have special meaning in the language. Generally it is recommended to do not use it as identifiers. But in kotlin there are some keywords which can be used as identifiers in some situations. There are basically four types of keywords in kotlin: Hard keywords Soft keywords Modifier keyword Special identifiers
硬關鍵字
在 kotlin 有24個硬關鍵字, 在任何情況下都不能用作標識符。 下面是硬關鍵字的列表。
Hard Keywords There are 24 hard keywords in kotlin which cannot be used as identifiers in any situation. Below is the list of hard keywords.

軟關鍵字

Soft Keywords

Modifier Keywords
There are 29 modifier keywords in kotlin. These tokens acts as keywords in modifier lists of declaration and can be used as identifiers in other context. Below is a list of modifier keywords.

特殊標識符
以下兩個特殊標識符由編譯器在特定上下文中定義, 可用作其他上下文中的常規標識符。 下面是這兩個標識符的列表。
Special Identifier
Following two special identifiers are defined by the compiler in specific context and can be used as regular identifiers in other context. Below are list of that two identifier.
請避免將它們用作標識符。避免使用關鍵字作爲標識符。
所以, 夥計們, 這是關鍵字。請隨時詢問任何疑問。
堅持編碼, 保持愛。
Please Guys avoid them to use as identifiers. Its my best suggestion to you in just one word. Avoid Keywords as Identifiers.
So guys, that’s it for keywords. Feel free to ask for any queries.
Till then Keep Coding, Keep Loving.
