How to Send Data From One Activity to Second Activity in Android

This guide will explain and demonstrate how to "Transfer data between two activities using Intent." For this example, we have two activities: `activity_first`, which serves as the source activity, and `activity_second`, which acts as the destination. Data can be passed from one activity to another using the `putExtra()` method, and retrieved in the second activity using the `getStringExtra()` method.
