In Java it’s called varargs, and the syntax looks like a regular parameter, but with an ellipsis (“…”) after the type: The vararg parameter must always be the last parameter in the method signature, and is accessed as if you received an array of that type (e.g. Object[] in this case).
With params you can call your method like this: Without params, you can’t. Additionally, you can call the method with an array as a parameter in both cases: That is, params allows you to use a shortcut when calling the method. Unrelated, you can drastically shorten your method:
The *args and **kwargs is a common idiom to allow arbitrary number of arguments to functions as described in the section more on defining functions in the Python documentation. The *args will give you all function parameters as a tuple: The **kwargs will give you all keyword arguments except for those corresponding to a formal parameter as a dictionary. Both idioms can be mixed with normal arguments to … Read more
