Println( "print converted int array as string : "+ Arrays.toString(array)) converting list to array list.toArray(array) The returned list has length of the shortest collection. creating an empty intger array with size of list. Returns a list of values built from the elements of this collection and the other array with the same index using the provided transform function applied to each pair of elements. Convert List to Array in Kotlin [package Hence, to see the actual contents inside the array, you should call Arrays.toString() method.ģ. In Kotlin on the JVM, a mutable list is backed by an ArrayList. If you print directly returned array then it prints memory address of the array.
Next, call list.toArray(array) which internally copies all values from list to array. The sort() method modifies the list in-place, and a sorted() built-in. Kotlin base package has a function arrayOfNulls(int size) which takes the size of the array that should be created and it should hold the String type values.Īfter the array is created then it will have null values in it. This function takes several attributes in order to convert an arrayList into a String.Therefore, always array size should be as same as List when doing a conversion.
any transformation required over the String the remaining will be denoted by truncated sequence This number of elements will be printed
Its definition goes like this − fun Array.joinToString(
In order to do so, we will use a String function called joinToString() that is provided by the Kotlin library. In this article, we will see how we can convert an ArrayList in Kotlin to a String.
