Implement Hashmap with different value types in Kotlin

Is it possible to have a hashmap in Kotlin that takes different value types?

I've tried this:

val template = "Hello {{world}} - {{count}} - {{tf}}"

val context = HashMap<String, Object>()
context.put("world", "John")
context.put("count", 1)
context.put("tf", true)

... but that gives me a type mismatch (apparantly `"John"`, `1` and `true` are not Objects)

In Java you can get around this by creating types `new String("John")`, `new Integer(1)`, `Boolean.TRUE`, I've tried the equivalent in Kotlin, but still getting the type mismatch error.

context.put("tf", Boolean(true))

Any ideas?

In Kotlin, [`Any`][1] is the supertype of all the other types, and you should replace Java `Object` with it:

val context = HashMap<String, Any>()
context.put("world", "John")
context.put("count", 1)
context.put("tf", true)

For new visitors,It can also be done with this

val a= hashMapOf<Any,Any>( 1 to Exception(), 2 to Throwable(), Object() to 33)

Where both keys and values can be of any type.
