Kotlin Arrays


What is an Array?

An array is a single structure that stores several similar elements in an ordered sequence.

val fruits = arrayOf("Apple", "Banana", "Cherry") 

Why Use Arrays?

They help you store several values in one structure without creating many variables.


Accessing Elements

You can reach any item by its position (starting from zero):

println(fruits[0])    // Outputs: Apple

Modifying Values

Change a value by pointing to its index:

fruits[1] = "Blueberry"

Size of Array

Know how many things are inside:

println(fruits.size)   // Outputs: 3

Loop Through Items

Check or use each value using a loop:

for (item in fruits) {     
     println(item)
} 

Create Specific Types

Arrays can also hold numbers or other types:

val numbers = arrayOf(10, 20, 30) 
Val letters = arrayOf('A', 'B', 'C') 

Empty Array

Start with an empty list if needed:

val emptyArray = emptyArray<String>()
