Java: Default Methods and Multiple Inheritance Rules

Class methods take precedence over interface default methods.

When a class inherits a method from a superclass and a default method from an interface, the class method is prioritized. For instance, if 'Product' extends 'Item' and implements 'Sellable', where 'Item' has 'display()' and 'Sellable' has a default 'display()', 'Product' will use 'Item's 'display()'.
