Correct Kotlin variable declaration
Computer Science
ScanSolve AI Answer
Answer
In Kotlin, variables are declared using either val for read-only (immutable) variables or var for mutable variables.
val (immutable variable):
val variableName: Type = initialValue
Example:
val message: String = "Hello, Kotlin!"
val year = 2023 // Type inference
var (mutable variable):
var variableName: Type = initialValue
Example:
var count: Int = 0
var name = "Alice" // Type inference
Kotlin also supports type inference, meaning you can often omit the type declaration if the initial value makes the type clear.
