Vararg-Schlüsselwort: vararg wird in einer Methodendeklaration verwendet, um anzuzeigen, dass eine variable Anzahl von Parametern akzeptiert wird.; Spread-Operator: Ein Sternchen ( *) vor einem Array, das in Funktionsaufrufen verwendet wird, um den Inhalt in einzelne Parameter zu entfalten.. Kotlin provides us to achieve the same by defining a parameter of a function as vararg. We can pass n number of parameters to a vararg variable of the defined datatype or even of a generic type. Let me give you an example. We need a function which takes n number as inputs and returns the average of all the inputs In Java, the vararg parameter has to be the last one in the parameters list — so you can only have one vararg parameter. While in Kotlin, the vararg parameter doesn't have to be the last one in the list, multiple vararg parameters are still prohibited
