Following is an example to print all elements of a list using for loop. To iterate over all the elements of a list, for loop can be used. But there is still arrayListOf () in Kotlin. MutableList is basically an ArrayList in Kotlin. Instead, its like listOf (1, 2, 3, 4,) for a normal list, and mutableListOf (1, 2, 3, 4,) for a mutable (editable) list.

The filtered output contains elements that satisfy the predicate we passed to filter() function. Since there are no list literals in Kotlin. Kotlin Program – example.kt fun main(args: Array) You can also use array style accessing of elements using square brackets. nums.shuffle () The shuffle method randomly rearranges the list elements. The addAll adds multiple elements at the end of the list. nums.add (6) nums.add (7) nums.addAll (listOf (8, 9, 10)) The add adds a new element at the end of the list. In that case, the collect () method will return an empty result container, such as an empty List, an empty Map, or an empty array, depending on the collector used in the. We create a mutable list of three integer elements. Suppose the stream to be collected is empty. List.get() is used to read elements of a list using index. When we use the standard collectors, the collect () method of the Java Stream API will not return null even if the stream is empty. ListB is a mutable list of type MutableList. abstract fun add(index: Int, element: E) Common JVM JS Native 1. abstract fun add(element: E): Boolean Inserts an element into the list at the specified index.

Functions Common JVM JS Native 1.0 add Adds the specified element to the end of this list. ListA is an immutable list of type List, since each of the element in the list is of type String. The mutable list is invariant in its element type. Var listB = mutableListOf('Example', 'Program', 'Tutorial') In the following example, var listA = listOf('Example', 'Program', 'Tutorial') Therefore both String.EMPTY constant and any constant denoted by '' literal will be represented with the same empty string instance at run time. All non- Mutable_ collections in Kotlin are compile time read-only types by default, but not immutable.To initialize Kotlin List, use mutableListOf(vararg items : T) method. While it’s true that there can be many instances of empty string in a program, those empty strings that come from literal '' are usually interned by JVM.
