Comparing IntArray and Array in Kotlin
Kotlin provides a variety of options for working with arrays, and two common choices are IntArray and Array<Int>. While both options allow you to store a collection of integers, they have distinct characteristics and use cases. In this article, we’ll explore the differences between IntArray and Array<Int>, their benefits, and when to choose each one. […]
Guide to JVM Platform Annotations in Kotlin
Annotations are a powerful feature in Kotlin that allow you to add metadata and behavior to your code. In addition to Kotlin-specific annotations, you can also work with annotations that are specifically designed for the Java Virtual Machine (JVM) platform. These JVM platform annotations provide compatibility, interoperation, and control over how your Kotlin code interacts […]
Convert Kotlin Array to Varargs
In Kotlin, arrays and varargs (variable-length argument lists) are fundamental concepts that play a crucial role in function parameters and argument passing. There are situations where you might need to convert an array into varargs or vice versa, either for convenience or compatibility reasons. In this article, we’ll delve into the process of converting a […]
Difference Between fold and reduce in Kotlin
In Kotlin, both the fold and reduce functions are powerful tools for aggregating values within a collection. These functions enable developers to process elements and accumulate results in a concise and functional manner. However, they have distinct behaviors and use cases that differentiate them from each other. In this article, we will delve into the […]
Converting a List to Map in Kotlin
In Kotlin, collections play a crucial role in handling and manipulating data efficiently. Often, there arises a need to convert a list of elements into a map, where each element in the list is associated with a unique key in the map. This process can be extremely useful in various scenarios, such as data transformation, […]
HTTP Requests with Kotlin and khttp
Introduction to khttp khttp is a lightweight and user-friendly HTTP client library for Kotlin that simplifies making HTTP requests. It provides a more intuitive and concise syntax compared to the standard Java HTTP libraries. khttp is built on top of the Apache HttpClient library and allows you to perform various types of HTTP requests easily. […]
Java 8 Stream API Analogies in Kotlin
Introduction Java 8 introduced the Stream API, a powerful functional programming construct that allows you to perform operations on collections in a concise and expressive manner. Kotlin, being a modern programming language with a focus on functional programming, also provides similar features for working with collections. In this article, we’ll explore the Java 8 Stream […]
Kotlin Dependency Injection with Kodein
Introduction to Dependency Injection Dependency Injection (DI) is a design pattern used to manage the dependencies of an application by providing objects (dependencies) to a class instead of allowing the class to create them itself. This pattern promotes loose coupling between classes, making the code more maintainable and easier to test. In Kotlin, there are […]
Guide to the “when{}” Block in Kotlin
Introduction In Kotlin, the “when” expression is a powerful construct used for conditional branching. It is similar to the traditional “switch” statement in other programming languages, but with more flexibility and enhanced features. The “when” expression allows you to check an expression against multiple branches and execute the code block associated with the first matching […]
Difference Between “==” and “===” Operators in Kotlin
Introduction In Kotlin, you may come across two different comparison operators: “==” and “===” when working with conditionals or evaluating equality. Understanding the distinction between these operators is crucial to avoid unexpected behavior in your code. In this article, we’ll explore the difference between “==” and “===” operators in Kotlin and when to use each […]
