Kotlin
Local 'var' is never modified and can be declared as 'val'
Warning
New
Last modified: 03 December 2024 Reports local variables declared with the var
keyword that are never modified.
Kotlin encourages to declare practically immutable variables using the val
keyword, ensuring that their value will never change.
Example:
fun example() {
var primeNumbers = listOf(1, 2, 3, 5, 7, 11, 13)
var fibonacciNumbers = listOf(1, 1, 2, 3, 5, 8, 13)
print("Same numbers: " + primeNumbers.intersect(fibonacciNumbers))
}
The quick-fix replaces the var
keyword with val
:
fun example() {
val primeNumbers = listOf(1, 2, 3, 5, 7, 11, 13)
val fibonacciNumbers = listOf(1, 1, 2, 3, 5, 8, 13)
print("Same numbers: " + primeNumbers.intersect(fibonacciNumbers))
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
