Ellipsis is represented by this syntax (...) in Java programming.

The condition that parameter type followed by an ellipsis can occur a few times at the end of a parameter list.

In this statement, public static double mchee (double...num), it means that variable number of double (data type) values can be passed to this method.

Parameter type followed by an ellipsis indicates that the method receives a variable number of arguments of that particular type.

Variable-length argument lists can be used to create methods that receive an unspecified number of arguments.
