Week 2: Data Types and Variables

• Variables and Data Types:

  • Basic data types: Int, Float, Double, Char, String, Boolean.

  • Declaring and initializing variables using val and var.

• Operators:

  • Arithmetic, relational, logical, and assignment operators.

• Input and Output:

  • Using readLine() for user input and println() for output.

  • String interpolation and formatting.

• Hands-On Task: Create a program that takes user input and performs basic arithmetic operations.

2. Control Structures and Functions (Weeks 3-4)

Week 3: Control Structures

• Conditional Statements:

  • If, else, and else if statements.

  • When expression (switch case alternative).

• Loops:

  • For loops, while loops, and do-while loops.

  • Using break and continue statements.

• Hands-On Task: Write a program that uses loops and conditions to find the Fibonacci sequence.

Week 4: Functions

• Defining Functions:

  • Creating and calling functions.

  • Function parameters and return values.

• Lambda Expressions:

  • Understanding and using lambda expressions.

• Higher-Order Functions:

  • Passing functions as parameters and returning functions.

• Hands-On Task: Write a program that demonstrates the use of functions to calculate the factorial of a number.

3. Collections and Data Structures (Weeks 5-6)

Week 5: Lists and Arrays

• Arrays:

  • Creating, accessing, and modifying arrays.

  • Multidimensional arrays.

• Lists:

  • Understanding mutable and immutable lists.

  • Common list operations: adding, removing, and iterating.

• Hands-On Task: Create a program that manipulates an array of integers to find the maximum and minimum values.

Week 6: Sets and Maps

• Sets:

  • Understanding sets and their properties.

  • Common operations: union, intersection, and difference.

• Maps:

  • Creating and accessing maps (key-value pairs).

  • Common map operations: adding, removing, and iterating.

• Hands-On Task: Write a program that counts the frequency of characters in a given string using a map.

4. Object-Oriented Programming (Weeks 7-8)

Week 7: OOP Concepts

• Understanding OOP:

  • Key principles: Encapsulation, Inheritance, and Polymorphism.

• Creating Classes and Objects:

  • Defining classes and creating objects.

  • Primary and secondary constructors.

• Hands-On Task: Create a class representing a Book with properties and methods to display its information.

Week 8: Advanced OOP Concepts

• Inheritance:

  • Understanding inheritance and its types (single, multiple interfaces).

• Polymorphism:

  • Method overriding and dynamic method resolution.

• Abstract Classes and Interfaces:

  • Understanding abstract classes and implementing interfaces.

• Hands-On Task: Implement a class hierarchy for a simple e-commerce application.

5. Exception Handling and File I/O (Weeks 9-10)

Week 9: Exception Handling

• Understanding Exceptions:

  • What are exceptions and how they work.

• Using try, catch, finally:

  • Handling exceptions and the importance of the finally block.

• Creating Custom Exceptions:

  • Defining and throwing custom exceptions.

• Hands-On Task: Write a program that handles exceptions during file operations.

Week 10: File Handling

• File I/O Operations:

  • Reading from and writing to files using Kotlin's standard library.

• Working with CSV Files:

  • Reading and writing CSV files using libraries like OpenCSV or Kotlin CSV.

• Hands-On Task: Create a program that reads a list of products from a CSV file and displays them.

6. Advanced Topics and Applications (Weeks 11-12)

Week 11: Coroutines and Concurrency

• Understanding Coroutines:

  • Introduction to coroutines for asynchronous programming.

• Using Launch and Async:

  • Managing background tasks with coroutines.

• Hands-On Task: Write a program that demonstrates asynchronous programming using coroutines.

Week 12: Introduction to Android Development

• Getting Started with Android:

  • Overview of Android development with Kotlin.

  • Setting up Android Studio and creating your first app.

• Basic UI Components:

  • Understanding layouts, views, and user interactions.

• Hands-On Task: Build a simple Android application that displays a list of items.

Final Project

• Kotlin Project:

  • Students will create a comprehensive project that incorporates various topics learned throughout the course. This could be a console application, an Android application, or a desktop application that utilizes OOP, file handling, and asynchronous programming.
