Write a Kotlin Program to Print an Array

Printing an array is one of the most basic operations in programming.

In Kotlin, this operation is straightforward and can be accomplished with just a few lines of code.

In this tutorial, we will go over the steps to print an array in Kotlin.

First, let’s define an array. An array is a collection of elements of the same data type.

We can create an array in Kotlin by using the “arrayOf()” function. Here’s an example of an array of integers:

val numbers = arrayOf(1, 2, 3, 4, 5)

Now that we have our array, we can print it using a for loop.

In Kotlin, we can use the “for” loop to iterate over each element in the array and print it to the console.

Here’s the code to print our “numbers” array:

for (number in numbers) {
println(number)
}

The above code will iterate over each element in the “numbers” array and print it to the console. The “println()” function is used to print each element on a new line.

We can also use the “joinToString()” function to print the elements of the array as a string.

This function takes an optional separator and prefix and suffix values as parameters.

Here’s an example of how to use the “joinToString()” function to print our “numbers” array:

println(numbers.joinToString())

The above code will print the “numbers” array as a string with a comma separator.

We can also specify a different separator by passing it as a parameter to the “joinToString()” function.

For example, if we want to use a space separator, we can use the following code:

println(numbers.joinToString(separator = " "))

In conclusion, printing an array in Kotlin is a simple process that can be accomplished using a for loop or the “joinToString()” function.

By using these functions, we can easily print the elements of the array to the console in a clear and organized manner.
