![]() ![]() Following is an example where the loop iterates through the range and prints individual item. The set() method takes 2 parameters: the index of the element and the value to be inserted. We will study Kotlin Ranges in a separate chapter, for now you should know that Kotlin Ranges provide iterator, so we can iterate through a range using for loop. 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: The value which is equal or greater than start value and smaller or equal to end value comes inside the definedrange. A range defines a closed interval in the mathematical sense: it is defined by its two endpoint values which are both included in the range. ![]() Range expressions are created with operator (.) which is complemented by in and in.
