How to Remove Specific Element from an Array in Kotlin - Step by Step Examples

How to Remove Specific Element from an Array in Kotlin ?

Answer

To remove a specific element from an array in Kotlin, you can use the `filter` method or create a new array excluding the element to be removed.

✐ Examples

1 Remove Element using filter method

In this example,

We create an array named `numbers` with elements including the one to be removed.
We use the `filter` method to exclude the specific element from the array.
Finally, we get a new array without the specific element.

Kotlin Program

fun main() {
    val numbers = arrayOf(1, 2, 3, 4, 5)
    val elementToRemove = 3
    val filteredNumbers = numbers.filter { it != elementToRemove }
    println("Array after removing $elementToRemove: $filteredNumbers")
}

Output

Array after removing 3: [1, 2, 4, 5]

2 Remove Element by creating a new array

In this example,

We create an array named `colors` with elements including the one to be removed.
We iterate through the array and add elements to a new array, excluding the specific element.
Finally, we get a new array without the specific element.

Kotlin Program

fun main() {
    val colors = arrayOf("red", "green", "blue", "yellow")
    val elementToRemove = "green"
    val newArray = ArrayList<String>()
    for (color in colors) {
        if (color != elementToRemove) {
            newArray.add(color)
        }
    }
    println("Array after removing $elementToRemove: $newArray")
}

Output

Array after removing green: [red, blue, yellow]
