How can I suppress unchecked cast warnings?

问题:

Having the following code:

fun doSomething(): List<String> {

    val test: List<*> = arrayListOf("test1", "test2")

    return test as List<String>
}

Is there some way to suppress the unchecked cast warning that comes up in the last line? I tried to use the standard Java way @SuppressWarnings("unchecked") at the method level, but it didn't work.

回答1:

Adding @Suppress("UNCHECKED_CAST") (also possible through IDEA's Alt+Enter menu) to any of statement, function, class and file should help.
