Kotlin Lists
Working with Lists
Kotlin lists use List and MutableList for immutable/mutable data.
Introduction to Kotlin Lists
Kotlin provides two main types of lists: List and MutableList. List is an immutable collection, meaning that the elements cannot be changed once the list is created. On the other hand, MutableList allows modification of the list's contents.
Creating Immutable Lists
To create an immutable list in Kotlin, you can use the listOf() function. This function returns a List that cannot be modified.
Creating Mutable Lists
For a mutable list, use the mutableListOf() function. This creates a MutableList that you can modify by adding, removing, or updating elements.
Accessing Elements in a List
Elements in both List and MutableList can be accessed using index-based access. Remember that indices start from 0.
Modifying Mutable Lists
While you cannot modify an immutable list, a MutableList provides several methods for modification, such as add(), remove(), and set().
Iterating Over Lists
Kotlin provides multiple ways to iterate over a list, such as using a for loop or the forEach method.
Conclusion
Kotlin's List and MutableList provide robust options for working with collections of data. Choosing between immutable and mutable lists depends on the requirements of your application.
