#var-args

The arguments passed to the method must be of a compatible data type to the varargs data type declaration. When invoking a method, the argument may be passed as an array or as a sequence of arguments. You may have other parameters in the method parameter list, but only one varargs parameter and it must be the last parameter listed. Methods may be overloaded with vararg parameters, but beware of a problematic situation where an empty argument array or no arguments is passed - I'll explain in the example code. Constructors may also be overloaded with vararg parameters, but beware of a problematic situation where an empty argument array or no arguments is passed - I'll explain in the example code. A legal declaration for the main method can include varargs, for example, public static void main(String ... args)

A Variable-Length Argument Array (Varargs) is a special kind of array that can be declared inside of a method or constructor parameter list. Varargs come in very handy when you do not know the exact number of arguments that will be passed to a method. Specifying a varags parameter is easy; first is the data type of the array, then three periods in a row, finally the reference variable name. Just like any other array declared in a parameter list, the reference variable will point to a new array object initialized to the values of the arguments passed to the method. The structure for a varargs array is like this: methodOrConstructorName( data-type ... referenceVariable )
