Passing Reference Data to Methods in Java
AP CSA Topic 3.6 Methods: Passing and Returning References of an Object
Want to learn what happens when you pass an object to a method in Java? In this Java 101 video, we explore how reference data is passed to methods and how changes made inside a method can affect the original object. Discover the difference between passing primitive values and passing object references, and learn why modifying an object's state inside a method is visible after the method returns. We'll walk through several examples that demonstrate how reference data is passed, trace what happens during a method call, and help you understand one of the most important concepts in object-oriented programming. This tutorial will build your confidence in working with objects and writing methods that use reference data effectively.
