Mar 17, 2024 · Simply put, in Java, a class can inherit another class and multiple interfaces, while an interface can inherit other interfaces. In this article, we’ll start with the need for inheritance, moving to how inheritance works with classes and interfaces.

Jun 21, 2018 · What you intended to do is either of the following: Override the method: private String name="Animal"; public String getName() { return this.name; public String getName() { return "Cat"; You can also declare a different field in the subclass, but that would be a bad idea still.
