Populating the data in array

Question

How to populate the array without iterating it with known size and value?

Example: If I want to create an array of size 5 with values 1. I don't want to iterate with size 5 and use add method. Is there any other way?

I am not sure what data structure you are talking about when you say "use add method". Are you referring to a list rather than an array? — Manish

Instantiating a string array with variables:

String foo = getFoo();
String bar = getBar();
String[] myStringArray = { foo, bar};

Instantiating a string with literals:

String[] myStringArray = {"foo", "bar"};

Filling an existing array with some value:

Arrays.fill(myStringArray, "1");

int[] array = new int[5];
Arrays.fill(array, 1);

This should work.

I do not know what he was asking, as arrays do not have an add method :D

Arrays.fill(array, 0);
