Kotlin How to create dynamic Object

Question

In javascript we can do something like this

function putritanjungsari(data){
	console.log(data.name)
}

let data = {
	name:"putri",
	div:"m4th"
}
putritanjungsari(data)

In kotlin, i'am creating a function that accept an object as parameter then read it's properties later, how to do that in kotlin that targeting JVM?

Answer 1

If I understood your question correct, you are trying to have a variable that associates keys with some value or undefined(null in kt) if none are found. You are searching for a Map If you don't know what types you want, you can make a map of type Any? So

Map<String, Any?>

Which is also nullable

Map<String, Any>

If you don't want nullables

Your code for example:

fun putritanjungsari(data: Map<String, Any?>){
print(data["name"]) 
}

val data: Map<String, Any?> =mapOf(        
"name" to "putri",
"div" to "m4th" 
)
putritanjungsari(data)

Note that you can't add new keys or edit any data here, the default map is immutable. There is MutableMap (which is implemented the same, only it has a method to put new data)
