The contain() method can also be used to check the existence of an element in a list.

The in operator can be used to check the existence of an element in a list. Println('Size of the list ' + theList.size) Val theList = listOf('one', 'two', null, 'four', 'five') We can use size property to get the total number of elements in a list: Note - here it works like this operator in Java. Lets study them one by one: Using toString() function There are various ways to loop through a Kotlin list. When you run the above Kotlin program, it will generate the following output: Val theMutableList = mutableListOf('one', 'two', 'three', 'four') Val theList = listOf('one', 'two', 'three', 'four') To prevent unwanted modifications, obtain read-only views of mutable lists by casting them to List. Creating Kotlin Listsįor list creation, use the standard library functions listOf() for read-only lists and mutableListOf() for mutable lists. Kotlin mutable or immutable lists can have duplicate elements. The elements of list can be accessed using indices.

A Kotlin list can be either mutable ( mutableListOf) or read-only ( listOf). Kotlin list is an ordered collection of items.
