How to Remove Element from Array based on a Condition in Kotlin - Step by Step Examples
How to Remove Element from Array based on a Condition in Kotlin ?
Answer
To remove an element from an array based on a condition in Kotlin, you can use the `filter` method to create a new array excluding elements that match the condition.
✐ Examples
1 Remove Integers Greater Than 5
In this example,
- We create an array named `numbers` with elements including those to be removed based on the condition.
- We use the `filter` method with a condition to create a new array excluding integers greater than 5.
- Finally, we get a new array with integers not greater than 5.
Kotlin Program
fun main() {
val numbers = arrayOf(1, 6, 2, 7, 3, 8, 4, 9, 5);
val filteredNumbers = numbers.filter { it <= 5 };
println("Array after filtering: $filteredNumbers");
}
Output
Array after filtering: [1, 2, 3, 4, 5]
2 Remove Strings Starting with 'A'
In this example,
- We create an array named `words` with elements including those to be removed based on the condition.
- We use the `filter` method with a condition to create a new array excluding strings starting with 'A'.
- Finally, we get a new array with strings not starting with 'A'.
Kotlin Program
fun main() {
val words = arrayOf("Apple", "Banana", "Apricot", "Grape", "Mango");
val filteredWords = words.filter { !it.startsWith("A", ignoreCase = true) };
println("Array after filtering: $filteredWords");
}
Output
Array after filtering: [Banana, Grape, Mango]
