Varargs

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:...
