Kotlin Programming

Course Overview

Course Description:Kotlin is an easy-to-learn language with clear syntax, perfect for beginners.

Topics Covered:

• Basics of Kotlin syntax and programming concepts
• Data types, variables, and basic operations
• Control flow: loops and conditionals
• Functions and lambdas
• Object-oriented programming with classes and inheritance

Syllabus

Module 1: Kotlin Basics & Setup

• Introduction to Kotlin & installation (IntelliJ / Android Studio / Kotlin Playground)
• Variables (val, var), Data types, Type inference
• Operators & Expressions
• Control flow (if-else, when, loops)
• Functions & default arguments

LAB 1

• Install Kotlin + IntelliJ IDEA Community Edition
• Write programs: calculator, factorial, palindrome, Fibonacci
• Create a when-based mini grading system

Module 2: Collections, OOP & Exception Handling

• Arrays, Lists, Sets, Maps
• Null safety & ?. operator
• Classes & Objects, Constructors
• Inheritance, Abstract classes, Interfaces
• Exception handling (try, catch, finally)

LAB 2

• Build a student management system using classes & collections
• Handle null safety with ?.let and Elvis operator ?:
• Create a program for bank account management with deposit/withdraw

Module 3: Advanced Kotlin (Functional & Coroutines)

• Higher-order functions & Lambdas
• Extension functions
• Data classes & Sealed classes
• Generics
• Coroutines for concurrency (launch, async, await)

LAB 3

• Implement Lambda-based filtering on list of numbers
• Use extension function to add custom functionality to String
• Create a multitasking program using coroutines (e.g., downloading files simulation)

Module 4: Kotlin in Practice (Android & Backend)

• File I/O (read/write)
• Using libraries (Gradle dependencies)
• Kotlin for Android basics (Activities, Intents, UI)
• Kotlin for backend with Ktor/Spring Boot basics
• Capstone Project (end-to-end)

LAB 4

• Build a file reader/writer app
• Create a simple Android app with Kotlin (Hello World + Button click counter)
• Build a small REST API in Ktor
• Capstone: Develop a mini-project (To-do List App, Weather App with API, Chat App, or Expense Tracker)

Learning Outcome

• Understand Kotlin fundamentals, OOP, functional programming, and concurrency with coroutines.
• Develop Android and backend applications using Kotlin.
• Build complete projects integrating file I/O, libraries, and APIs.
