Standard functions for arrays and collections in Kotlin

admin KotlinTutorial Views 0 comments 10 min read

Kotlin has several standard functions for arrays and collections such as lists, sets or maps that make working with these data structures easier and more efficient. Some of these features are presented below, along with code examples and common use cases. isEmpty() and isNotEmpty() The isEmpty() function returns true if an array or collection such as List, Set, or Map is empty, that is, contains no elements; otherwise it returns false.

Introduction to object-oriented programming (OOP) in Kotlin. Classes and objects

admin KotlinTutorial Views 0 comments 7 min read

Object-oriented programming (abbreviated OOP) is an approach to developing software that aims to structure and organize software code using classes and objects. A class serves as a kind of blueprint or template for creating objects. It specifies the properties (known as attributes) and behavior (in the form of functions or otherwise known as methods) that an object has

Constructors in Kotlin

As described in the previous article, to create an object, a constructor of the class is called. If there are no specific instructions regarding a constructor at the class level, the compiler generates an empty parameterless constructor by default, as shown in the following example: However, it is also possible to define your own constructors on a class using the constructor keyword. A distinction is made between primary and secondary constructors. One

Packages in Kotlin

admin KotlinTutorial Views 0 comments 5 min read

In Kotlin, packages are collections of related functions, classes, objects, and type definitions. They are used to structure code into logical units and help to avoid naming conflicts between identically named functions and classes in different parts of a program. Organizing code in the form of packages is particularly important in large software projects. Packages help keep the code clear. They make maintenance easier

Inheritance in Kotlin

admin KotlinTutorial Views 0 comments 4 min read

In Kotlin, inheritance is a central concept of object-oriented programming. It allows a class to inherit properties and methods from another class, allowing you to extend existing class content or change its behavior. In the context of inheritance, the main distinction is between the superclass (or base class), which defines basic functionalities, and the subclass, which inherits these functionalities and can modify or extend them. Syntax of Inheritance in Kotlin In
