Anonymous array in Java

An array in Java without any name is anonymous array. It is an array just for creating and using instantly.

• We can create an array without name, such type of nameless arrays are called anonymous array.
• The main purpose of anonymous array is just for instant use (just for one time usage) .
• Anonymous array is passed as an argument of method

Syntax:

// anonymous int array 
new int[] { 1, 2, 3, 4};  

// anonymous char array 
new char[] {'x', 'y', 'z'); 

// anonymous String array
new String[] {"Geeks", "for", "Geeks"}; 

// anonymous multidimensional array
new int[][] { {10, 20}, {30, 40, 50} };

Output:

The sum is 6

NOTE: In the above example just to call sum method we required an array but after implementing sum method, we are not using array anymore. Hence for this one time requirement anonymous array is the best choice. Based on our requirement we can later give the name to anonymous array and Then it will no longer be anonymous.
Example:

int[] x = new int[]{1, 2, 3};
