KOTLIN RANGES | RANGE & DOUBLE DOT OPERATOR IN ANDROID STUDIO | HOW TO USE RANGES [ KOTLIN ]

Kotlin Ranges In Kotlin, the range is a collection of finite values which is defined by endpoints. The range in Kotlin consists of a start, a stop, and the step. The start and stop are inclusive in the Range and the value of step is by default 1. The range is used with comparable types. There are three ways for creating Range in Kotlin

Ranges and progressions Kotlin lets you easily create ranges of values using the rangeTo() function from the kotlin.ranges package and its operator form ... Usually, rangeTo() is complemented by in or !in ntegral type ranges (IntRange, LongRange, CharRange) have an extra feature: they can be iterated over. These ranges are also progressions of the corresponding integral types.

How to use Kotlin Range Expressions A range is a sequence of values defined by a start, an end, and a step. In this quick tutorial, we’ll have a look at how we can define and use ranges in Kotlin.

2. Using Kotlin Ranges In Kotlin, we can create ranges using the rangeTo() and downTo() functions or the .. operator. We can use ranges for any comparable type. By default, they’re inclusive, which means that the 1..4 expression corresponds to the values 1,2,3 and 4. In addition, there’s another default: the distance between two values, called a step, with an implicit value of 1. So now, let’s take a look at a few examples of creating ranges and using other useful methods to manipulate them. In Kotlin, the range is a collection of finite values which is defined by endpoints.

Kotlin Ranges Kotlin range is defined as an interval from start value to the end value. Range expressions are created with operator (. .) which is complemented by in and !in. The value which is equal or greater than start value and smaller or equal to end value comes inside the definedrange. While evaluating the above code valaToZ = 'a'..'z'as 'a'in aToZ returns true, 'b' in aToZ returns true and so on. The code valoneToNine = 1..9 evaluates as 1 in oneToNine returns true, but the evaluation 10 in oneToNine returns false. Integral Type Ranges

Integral type ranges (IntRange, LongRange, CharRange) are the ability to use in for loop. The compiler converts this integral type in simple analogue of Java's index for-loop. Example of Kotlin range.
