Then run the code and your output will be printed 🤓. All you need to do is call the specific function in the main function. Let’s look at how we could use ranges.īefore we begin writing our code, you can use the following to run the functions. We can use functions to create progressions and check for values in ranges. In other words, a range is an interval from the start value to the end value. Both the start and end values belong to the range too. That is, a range of 1 as the start value and 5 as the end value. A simple example would be, the values between 1 and 5 form a range. What are rangesĪ range is a collection of values determined by a start and stop value.

In this article, we will be taking a look at Kotlin ranges. 4 in 1.6 (true) The next example shows how we can use ranges with both if/else and when statements. To check if a value contained by this range you use the in keyword. a.z will include all of the characters from a-z and a.Z will include a-z+A-Z. We will address one of the solutions it offers: iterations. Kotlin also allows this notation for other common ranges, such as characters. The boilerplate code present in Java is also greatly reduced. Since it is compiled the same way as Java, its functions and methods ensure your code is more efficient. Kotlin provides easier ways to perform specific actions. Most of these solutions aim to make development easier and faster. What this condition is saying, in plain speech is, “Is examScore equal to 100? If so, print some output text”.Kotlin provides a wide range of solutions. The example above shows our two pieces of data: examScore and 100 as well as the comparison operator that is being used to evaluate the data: =. We will have a closer look at these operators after a few brief code snippets. Kotlin supports the same primary operators that many other programming languages, like Java. We make this comparison by evaluating a conditional statement which generally consists of two or more pieces of data that are separated by logical operators and/or comparison operators. When you want to measure something against another, you make a comparison or a check. (Recommended) If you’re following along, you should do so with the IntelliJ IDEA IDE – it’s FREE.

Understand how to define variables in Kotlin.

If you’re already familiar with other programming languages, such as Java, C, C++, C#, etc… you will find that the first part of this tutorial on conditionals and their operators will be a review. This tutorial also covers conditional operators, logical operators, and a variety of syntax that are used with each topic. In this tutorial, we are looking into conditionals, ranges, and the “when” statement in the Kotlin language.
