What will you learn in Mastering Kotlin Essentials Course
Understand Kotlin’s core syntax and null-safe type system to write concise, expressive code
Work with variables, values, and basic types, plus control structures:
if/when, loops, and exception handling
Define and use classes, interfaces, inheritance, and sealed/data/enum/annotation classes for robust domain modeling
Leverage object expressions, declarations, and extension functions to extend existing APIs without inheritance
Program Overview
Module 1: Variables, Values & Types
⏳ 30 minutes
Topics:
valvs.var, primitive and nullable types, type inferenceHands-on: Declare and use variables safely, handle nullable operations with
?.and?:
Module 2: Control Flow & Null Safety
⏳ 45 minutes
Topics:
ifexpressions,whenstatements, loops (for,while), null-checksHands-on: Write control-flow logic for a simple calculator and safely navigate nullable data
Module 3: Classes, Interfaces & Inheritance
⏳ 1 hour
Topics: Primary/secondary constructors, inheritance modifiers, interfaces, abstract classes
Hands-on: Model a vehicle hierarchy with shared behavior and polymorphic dispatch
Module 4: Advanced Class Types & Objects
⏳ 1 hour
Topics: Data classes, sealed classes, enum classes, annotation classes, object declarations
Hands-on: Create a sealed class hierarchy for API responses and use data classes for DTOs
Module 5: Functions & Extension Functions
⏳ 45 minutes
Topics: Top-level functions, default and named parameters, extension functions, higher-order functions
Hands-on: Write utility extensions for
StringandCollectionto streamline common tasks
Module 6: Collections & Generics
⏳ 1 hour
Topics: List/Set/Map APIs, lambdas,
map/filter/reduce, variance, and generic functions/classesHands-on: Process a list of user objects to filter, transform, and aggregate data
