Array: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-array/index.html

List: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/index.html

Set: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-set/index.html

Map: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-map/index.html

And ArrayList: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-array-list/

There are some differences of their structures and the way to use.
