In this tutorial you will learn about ArrayList via simple step by step examples.
Example 1: ArrayList
Let us look at a simple ArrayList 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:
ArrayList.kt
- In your editor or IDE, create a file known as
ArrayList.kt
. - Then add the following code:
(a). ArrayList.kt
package Collections.ArrayList
fun main(args : Array<String>) {
val list = arrayListOf(1, 2, 3)
list.forEach { println(it) }
val list2 = arrayListOf(Pair("Bill", "Clinton"),
Pair("George W.", "Bush"),
Pair ("Barack", "Obama"))
list2.add(Pair("Hillary", "Clinton"))
list2.forEach { println("${it.first} - ${it.second}") }
}
Step 4: Run
Copy the code, build and run.
