In this tutorial you will learn about Pair And Triple via simple step by step examples.
Example 1: Pair AndT riple
Let us look at a simple Pair And Triple example written in Kotlin Programming Language. Follow the following steps:
Step 1: Create Project
- Open your favorite Kotlin IDE.
- In the menu go to
File --> Create New Project
.
Step 2: Add Dependencies
No dependencies are needed for this project.
Step 3: Write Code
Our code will comprise the following Kotlin files:
PairAndTriple.kt
- In your editor or IDE, create a file known as
PairAndTriple.kt
. - Then add the following code:
(a). PairAndTriple.kt
package Objects.PairAndTriple
//In the old days (Kotlin M2), Kotlin has tuples. They have been removed at M3. Now you can use instead Pair or Triple (they are implemented as data class)
fun main(Args : Array<String>) {
var greet = Pair("Hello", "World")
val(word1, word2) = greet
println("${greet.first} ${greet.second} or $word1 $word2")
var greet2 = Triple("I", "am", 34)
val(word3, word4, number) = greet2
println("${greet2.first} ${greet2.second} ${greet2.third} or $word3 $word4 $number")
//extension functions "to" creates pair
val greet3 = "Hello" to "World2"
println ("${greet3.first} ${greet3.second}")
}
Step 4: Run
Copy the code, build and run.
