Throws

@Target(allowedTargets = [AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER, AnnotationTarget.CONSTRUCTOR])
annotation class Throws(val exceptionClasses: KClass<out Throwable>)(source)

This annotation indicates what exceptions should be declared by a function when compiled to a JVM method.

Example:

@Throws(IOException::class)
fun readFile(name: String): String {...}
Content copied to clipboard

will be translated to

String readFile(String name) throws IOException {...}
Content copied to clipboard
