Array is a data structure in the java. That helps us to Store data in an efficient way.

1) Using the new keyword with size only:

Syntax:

int[] array_name = new int[array_size];

Use this method when you know the number of elements you want but don’t have their values yet.

Example:

int[] profit = new int[5];

We create an array of size 5 where each element is a default value i.e (0 of integers).

Let's print this array:

int[] profit = new int[5];
        
System.out.println(profit);

Output:

[I@659e0bfd

We got this.

To get the elements from this array is pretty simple by using the indexing:

int[] profit = new int[5];
System.out.println(profit[2]);
