How to create a Two Dimensional Array in Kotlin - Step by Step Examples

How to create a Two Dimensional Array in Kotlin ?

Answer

To create a Two Dimensional Array in Kotlin, you can use the Array constructor with the specified dimensions.


✐ Examples

1 Creating a 2D Array of Integers

In this example,

  1. We initialize a 2D array of integers named matrix with dimensions 3x3.
  2. We assign values to the elements of the array.
  3. The outer loop iterates over rows, and the inner loop iterates over columns to fill the array.

Kotlin Program

fun main() {
    val matrix = Array(3) { IntArray(3) }
    for (row in matrix.indices) {
        for (col in matrix[row].indices) {
            matrix[row][col] = row + col
        }
    }
    println(matrix.contentDeepToString())
}

Output

[[0, 1, 2], [1, 2, 3], [2, 3, 4]]

Summary

In this tutorial, we learned How to create a Two Dimensional Array in Kotlin language with well detailed examples.
