How can reified parameters be applied in inline functions in Kotlin?

Answer from AI
In Kotlin, reified parameters allow obtaining information about the type of a parameter at runtime, which is usually impossible due to type erasure. This is only possible in inline functions with the reified keyword.
Example of usage:
inline fun <reified T> Gson.fromJson(json: String): T {
return this.fromJson(json, T::class.java)
}
Here, the fromJson function can get the class T at runtime thanks to reified, which allows calling T::class.java.
Thus, reified parameters are used for working with types inside inline functions without the need to explicitly pass the class.
