Scala | Repeated Method Parameters

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: 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:
  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:
  Output:

  GeeksforGeeks is a Computer_Sciecne_Portal
  

  Here, format is used to format strings.
