System.out.println().
Replacing the code gets rid of the dependency to Java and makes the idiomatic Kotlin code.
The quick-fix replaces the Java method calls on the same Kotlin call.
Example:
import java.util.Arrays
fun main() {
val a = Arrays.asList(1, 3, null)
}
After the quick-fix is applied:
fun main() {
val a = listOf(1, 3, null)
}
