Kotlin allows functions to be defined so that they would accept a variable number of arguments. Hence, this feature is called varargs. Varargs allow users to pass in a comma-separated list of arguments, which the compiler will automatically wrap into an array. Java developers will already be familiar with the feature, which, in Java, looks like the following:
public void println(String.. args) { }
The Kotlin equivalent is to use the vararg keyword before the parameter name:
fun multiprint(vararg strings: String): Unit { for (string in strings) println(string) }
This would be invoked by simply enumerating the arguments as in the following example:
multiprint("a", "b", "c")
Functions can have regular parameters, and, at most, one parameter marked as vararg:
fun multiprint(prefix: String, vararg strings:...
