+# Iterating an array of `Person` objects
+* **Objective:**
+    * To concatenate the details of `Person` objects by iterating an array  
+
+* **Purpose:**
+    * To demonstrate practical understanding of `while`, `for`, and `for each` loops.
+
+* **Getting started:**
+    * The `PersonHandler` class has 3 [method stubs](https://en.wikipedia.org/wiki/Method_stub) to be completed.
+        * The methods contain line-by-line comments to guide you through the process.
+    * Ensure all tests cases pass successfully.
