contentDeepToString

inline fun <T> Array<out T>.contentDeepToString(): String

Platform and version requirements: Kotlin 1.1

Returns a string representation of the contents of this array as if it is a List. Nested arrays are treated as lists too.

If any of arrays contains itself on any nesting level that reference is rendered as "[...]" to prevent recursion.

import kotlin.test.*

fun main(args: Array<String>) {
//sampleStart
val matrix = arrayOf(
        intArrayOf(3, 7, 9),
        intArrayOf(0, 1, 0),
        intArrayOf(2, 4, 8)
)

println(matrix.contentDeepToString()) // [[3, 7, 9], [0, 1, 0], [2, 4, 8]]
//sampleEnd
}
