Final answer:
In an interface with default methods, classes that implement this interface do not need to implement the default methods, but can freely use or override them to suit their specific needs.
Step-by-step explanation:
When you code a class that implements an interface with default methods, you have options regarding those methods. A default method is a method defined in the interface with the default modifier, and it provides a default implementation that can be used by classes implementing the interface. This is a feature introduced in Java 8 to provide more flexibility and allow interfaces to evolve without breaking existing code.
The correct answer to the question is that when you implement an interface with default methods, you don’t need to implement its default methods. However, you are still free to override these methods with your own implementation if you choose. Overriding would provide your class with a different behavior from the default. It’s also worth noting that you can indeed use the default methods defined in the interface in your class, and doing so can reduce redundancy and save you time when those default behaviors are suitable for your needs.
