for Kotlin collections that are indexed by `Int` (...

for Kotlin collections that are indexed by Int (such as List ), is Int.MAX_VALUE the maximum number of elements they can store?

[ephemient]

in theory. a List implementation could contain more than Int.MAX_VALUE elements (the ones beyond that won't be indexable, but they might exist). however, the typical ones are backed by arrays, and while neither Kotlin nor the JVM document what the maximum array size is, most code assumes it's somewhere near Int.MAX_VALUE (e.g. https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/jdk/internal/util/ArraysSupport.java#L589)

thank you! I had a difficult time finding this info
