String… Parameter in Java

See the English answer > varargs and the '...' argument 3

public void method(String... strs);

What does "..." mean? It looks like I need to call the same method with a single string actual parameter, and multiple string actual parameters

Java has no optional parameters (as far as I know), so I'm a little confused here

Solution

It's called varargs; http://docs.oracle.com/javase/6/docs/technotes/guides/language/varargs.html

This means that you can pass any number of parameters (even zero) to the method

In this method, the parameters will be automatically put into the array of the specified type for accessing each parameter
