What are Strings... objects called as?

Question

I didn't know what to look for so i couldn't google this one but..

What are String... parameters called as ?

And how do you get individual strings when more than one String object is passed through a String... object ?

And you can treat them as arrays/iterables in your code so accessing individual elements shouldn't be a problem. — Sanjay T. Sharma, Nov 23 '13 at 18:01

A String... is syntactic sugar for an String[] and you access the values of the String array just like any other String array. In fact you can write this simple method.

public static <T> T[] asArray(T... ts) {
    return ts;
}

This takes a vararg array can returns an array.

The key difference is that you can write

asArray(1, 2, 3); // much shorter.

instead of having to write

asArray(new Integer[] { 1, 2, 3 });

this is a feature introduced with jdk 1.5. basically the last parameter of a method can be declared as ... and that means

from method caller pespective you can pass zero, one or many instances of that type
within method the .... param is basically seen as an array
