Java methods should be replaced with Kotlin analog

Reports a Java method call that can be replaced with a Kotlin function, for example, 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.


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) }
