Varargs Java
varargs:
It's possible to pass an arbitrary number of the same type arguments to
a method using the special syntax named varargs (variable-length arguments).
(Varargs can be used when we are unsure about the number of
arguments to be passed in a method)
Use varargs for any method (or constructor) that needs an array of
T (whatever type T may be) as input
One good example is String.format.
The format string can accept any number of parameters.
