Project structure and build basics in Kotlin - Mini Project: Build & Apply

Project structure and build basics

📖 Scenario: You are starting a simple Kotlin project to understand how to organize files and build a program.

🎯 Goal: You will create a basic Kotlin project with a main function, add a configuration variable, write a simple function, and print the result.

📋 What You'll Learn

Create a Kotlin file with a main function

Add a configuration variable inside the main function

Write a function that uses the configuration variable

Print the output of the function

💡 Why This Matters

🌍 Real World

Understanding project structure and build basics helps you start any Kotlin application clearly and organized.

Knowing how to set up main functions, variables, and functions is essential for Kotlin developers building apps or backend services.

1

Create the main function

Create a Kotlin main function with no parameters and inside it declare a variable projectName set to the string "MyKotlinProject".

Kotlin

fun main() {
    // Your code here
}

Need a hint?

Use fun main() { } to create the main function and inside it declare val projectName = "MyKotlinProject".

2

Add a configuration variable

Inside the main function, add a variable called version and set it to the string "1.0".

Kotlin

fun main() {
    val projectName = "MyKotlinProject"
    // Your code here
}

Need a hint?

Declare val version = "1.0" inside the main function below projectName.

3

Write a function to show project info

Write a function called showProjectInfo that takes two parameters: name and version, both strings. The function should return a string formatted as "Project: {name}, Version: {version}". Call this function inside main using the variables projectName and version, and store the result in a variable called info.

Kotlin

fun main() {
    val projectName = "MyKotlinProject"
    val version = "1.0"
    // Your code here
}

// Your function here

Need a hint?

Define fun showProjectInfo(name: String, version: String): String returning the formatted string. Then call it inside main and assign to info.

4

Print the project info

Add a println statement inside the main function to print the variable info.

Kotlin

fun main() {
    val projectName = "MyKotlinProject"
    val version = "1.0"
    val info = showProjectInfo(projectName, version)
    // Your code here
}

fun showProjectInfo(name: String, version: String): String {
    return "Project: $name, Version: $version"
}

Need a hint?

Use println(info) inside main to display the project info.
