Taking array input using the Scanner class in Java is a common task when developing programs that require user input for arrays. Whether you're working with integer arrays, string arrays, or arrays of other data types, the Scanner class provides a straightforward way to handle user input efficiently. Here's a step-by-step guide on how to do it:

Step 1: Import the Scanner class
