Program/Source Code:
The source code to get the first item from the array is given below. The given program is compiled and executed successfully.
Output:
Explanation:
In the above program, we created an array of integers with few elements. Then we got the first item from the array using the first() method and assigned the item into the item variable. After that, we printed the result.
