Question

Possible Duplicates:
Java array argument “declaration” syntax
What is the ellipsis for in this method signature?

I’ve stumbled upon a function that has a String… strings as a parameter. What is the significance of this? I’m assuming it means any number of string arguments but isn’t that the point of List?

function doStuff(String... strings) {
    //Code
}

I’d appreciate an explanation of its purpose and usage in applications. Thanks

Answer 1

I is the syntax for specifying varargs i.e. specifying that a method can take a variable number of arguments.

The three periods after the final parameter’s type indicate that the final argument may be passed as an array or as a sequence of arguments. Varargs can be used only in the final argument position.
