This free online course will provide the techniques and knowledge required to build mobile applications using Kotlin.

We have designed this course to equip developers with the abundant skills and knowledge required to develop mobile applications. We begin by teaching you how to set up Kotlin on a Windows, Mac or Linux operating system. Then we introduce you to Kotlin basics. You will learn about variables, data types, strings and arrays, data type conversion and making comments. Next, you will learn about operators used in Kotlin, which will include the arithmetic operator, relational, assignment, bitwise, unary and logical. Then discover control statements in Kotlin, their functions and the conditional 'If' statement, which checks for some specified conditions and runs the codes based on that. Next, explore the functions of loops, including the ‘for loop’ used to iterate over a part of a program multiple times, the ‘while loop’ and the ‘infinite loop’.

This course will also teach you the functions of the ‘break’ and ‘continue’ statements in Kotlin. Investigate how it performs tasks and enhances the performance of other functions in Kotlin. Research how to solve a problem by creating a function called ‘recursion’ multiple times until the set condition is met. Learn how a ‘try’ block can be used in exception handling and make nullable and non-nullable variables. Examine Kotlin classes, the list of functions, the mutable list, an array list as well as how to efficiently retrieve the corresponding values to each key using the mutable map. Finally, analyse object-oriented programming and the properties of a nested class, visibility modifiers and types, including the private and public modifiers. Then you will learn how to call a Java code from Kotlin and call a Kotlin file from Java.

Kotlin is a cross-platform general programming language used by over sixty percent of app developers. It has a mature language and environment, making it very user-friendly, enabling easier and swifter application development. This course will teach you how to set up Kotlin, the basics and control flow statements like ‘loop’ and ‘when loop’. You will also learn about the error and exception handling and class and how to call Java codes from Kotlin and vice versa. So, why are you waiting? Take this course today and enhance your application development skills.
