How to Iterate over a Two Dimensional Array in Kotlin ?

Answer

To iterate over a Two Dimensional Array in Kotlin, you can use nested loops.

✐ Examples

1 Iterating over a 2D Array of Integers

In this example,

We declare and initialize a 2D array of integers named matrix with dimensions 3x3.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

Kotlin Program

fun main() {
    val matrix = arrayOf(arrayOf(0, 1, 2), arrayOf(1, 2, 3), arrayOf(2, 3, 4))
    for (row in matrix) {
        for (element in row) {
            print("$element ")
        }
        println()
    }
}

Output

0 1 2 
1 2 3 
2 3 4

2 Iterating over a 2D Array of Strings

In this example,

We declare and initialize a 2D array of strings named matrix with dimensions 2x2.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

Kotlin Program

fun main() {
    val matrix = arrayOf(arrayOf("Hello", "World"), arrayOf("Kotlin", "Java"))
    for (row in matrix) {
        for (element in row) {
            print("$element ")
        }
        println()
    }
}

Output

Hello World 
Kotlin Java
