In Scala, Repeated Method parameters are supported, which is helpful when we don’t know the number of arguments a method requires. This property of Scala is utilized in passing limitless parameters to a method defined.
Important points :

• The methods with Repeated Parameters should have each of the parameters of same type.
• A Repeated parameter is always the last parameter of the method defined.
• The method defined by us, can have only one parameter as Repeated Parameters.

Example:

58

In order to add any number of extra parameters, we need to put * mark after the type of the parameter being used.
Some more examples of Repeated Parameters:

• An Array can be passed in the Repeated Parameter method.
  Example:
  
  
  
  

  
  

  
  
  

  // Scala program of repeated  // parameters    // Creating object object arr {        // Main method     def main(args: Array[String])     {            // Creating a method with         // repeated parameters         def mul(x: Int*)         : Int =         {                // Applying 'product' method to              // perform multiplication             x.product                }            // Displays product         println(mul(Array(7, 3, 2, 10): _*))     } }

  Output:

  420
  

  In order to pass an array in the defined method, we need to put a colon i.e, : and _* mark after passing the values in the array.

• An example to show that Repeated Parameters are always the last parameter of the method defined.
  Example:

  
  

  
  
  

  // Scala program of repeated  // parameters    // Creating object object str {        // Main method     def main(args: Array[String])     {            // Creating a method with         // repeated parameters         def show(x: String, y: Any*) =         {                    // using 'mkString' method to             // convert a collection to a             // string with a separator             "%s is a %s".format(x, y.mkString("_"))         }            // Displays string          println(show("GeeksforGeeks", "Computer",                             "Sciecne", "Portal"))     } }

  Output:

  GeeksforGeeks is a Computer_Sciecne_Portal
  

  Here, format is used to format strings.
