To test this method, we created three arrays: strArray, intArray and charArray with string, integer, and character elements.įor all of these arrays, the item at index 2 is removed. fun Sequence.withIndex(): Sequence.

We can use the forEachIndexed () function to retrieve the current index. The removeItem method takes the array and the index as its parameters and returns the modified array. Get the Current Index of an Item in a forEach Loop Using forEachIndexed () in Kotlin. However you can do method or function overload, using this as implicit objectįor instance, you can program reverse substring, but here you cannot use negative numbers, because we need a different parameters profile regarding to the original method: fun String.Fun main ( ) Arrays are of fixed length in Kotlin and we can’t remove an item from an array or we can’t modify an array. Var sObject = py.reversed().slice(0.2).reversed() Kotlin program to remove specific elements from an array using index: In this post, we will learn how to remove specific elements from an array in Kotlin. List(or Arrays) in Kotlin var py = arrayOf(1, 2, 3, 4, 5, 6, 7, 8) Val sObject = pyString.reversed().substring(0, 3).reversed() // index 3 excluded Strings In Kotlin val pyString = 'Python'

do-while executes the body and then checks the condition. There is no direct function for slicing, but one can write an user defined function or easily simulate using reversed function, that works with string, lists and arrays. The difference between them is the condition checking time: while checks the condition and, if it's satisfied, executes the body and then returns to the condition check.
