To define a range for the primitive type we use rangeTo() function. There are built-in implementations of ranges for the integral primitive types, like Int, Long and Char. In this post, we’ll see quick examples of creating ranges using various range expressions and iterating over ranges in Kotlin. It stores handle to first and last elements of the range and also provides contains(value: T): Booleanand isEmpty(): Boolean functions that check two conditions: if the given value belongs to the range and if the range is empty. An interface from kotlin.ranges package called ClosedRange is a base declaration that models the idea of the range. The idea of a range itself can be seen as an abstract data type that models a closed scope of values or a set of objects that can be iterated through, in a concise way. Let’s get started 🚀! Iterating through primitive types

Next, we are going to implement a custom progression for the LocalDate class.

First, we are going to discover built-in range implementations for the integral types like Char, Int or Long. In this post, we are going to explore how to use range expressions in action. In order to make the syntax for loop iteration and control flow statements safe and natural to read, Kotlin standard library provides a concept of range.
