Explanation:
When working with Kotlin, it is important to ensure that you have a dependency on the Kotlin standard library. The Kotlin standard library provides essential functions, classes, and extensions that facilitate various programming tasks.
To include the Kotlin standard library in your project, you can add the following dependency in your build.gradle file:
<dependencies>
<dependency>
group: 'org.jetbrains.kotlin', name: 'kotlin-stdlib', version: '1.5.10'
</dependency>
</dependencies>
Example:
Let’s say you want to use some Kotlin standard library functions, such as `println` and `readLine`, in your Kotlin program. Here’s how you can do it:
import kotlin.io.println // Import the `println` function from the Kotlin standard library
import kotlin.io.readLine // Import the `readLine` function from the Kotlin standard library
fun main() { // Entry point of the program
println("Enter your name:")
val name = readLine() // Reading input from the user using `readLine` function
println("Hello, $name!") // Printing the greeting message using `println` function
}
In the above example, we import the `println` and `readLine` functions from the Kotlin standard library using the `import` statement. These functions allow us to print output to the console and read input from the user, respectively. We then use these functions in the `main` function to greet the user by taking their name as input and printing a personalized greeting message using string interpolation.
