operator, kind of like how adding inc allows us to use the ++ operator. The rangeTo method will allow us to iterate over our range using the. The set() method takes 2 parameters: the index of the element and the value to be inserted.Since we’re defining our custom range, CustomColor class must implement the rangeTo method. The get() method takes a single parameter-the index of the element and returns the value of the item at that index. The get() and set() functions are said to be member functions. Therefore, we can access the data of a class object via its member functions. Now, let’s see how to access and modify them.Īs you know, an array in Kotlin is basically a class. So far, we have seen how to create and initialize an array in Kotlin. Other factory methods available for creating arrays: These classes do not extend the Array class however, they implement the same methods and properties.įor example, the factory method to create an integer array is: Kotlin Explained: Custom Range Expressions Traversing through dates using Kotlin range expressions Photo by Curtis MacNewtonon Unsplash Inorder to make the syntax for loop iteration and.
