In the below examples, we have tried to print the number and alphabets in a reversed manner using the same method as we have used in examples 1 and 2, but the same concept doesn’t work as the start value must be small than the end value. There are some cases where we want to print numbers or alphabets in a reversed manner. Here we have used x variable to store the alphabets, as we want to print the alphabet from a to k, we have defined start value as a and end value ask. Here we have written a program to print the alphabets from a to k using range Check if Number is in a given RangeĪfter you have created a range variable, if you want to check if a given number falls in that range or not, then we can do it easily using the in operator with if condition.Here we have used x variable to store the number, as we want to print the number from 1 to 10, we have defined the start value as 1 and the end value as 10. In the code example above we are creating a range from 1 to 9, including both 1 and 9 in it. Here is a basic example of it: val range = 1.rangeTo(9) We can also use rangeTo() function to create the range. Kotlin Range using the rangeTo() Operator: The only shortcoming is that we cannot create a range with a pattern where we skip/jump numbers, for example, if you want to create a range of number 1, 3, 5, 7, etc. If you want to create a range of numbers with all the numbers included in the range then using the. In the code example above, we created a range using the. Let us create a range from 1 to 9 using the. operator and the rangeTo() function, let's cover them one by one.

Kotlin: Create a rangeĪs we mentioned above, we can either use the.

We can create a range with the help of rangeTo() function in Kotlin or using the. The range may also have a step (step is used to jump numbers or characters while defining the range from start to end boundaries). The boundary points are start & end and both of them are included in the range. In the mathematical sense, a range is a sequence of numbers, characters, etc. In this tutorial, we will discuss about range in Kotlin.
