An abstract class may contain both abstract and non-abstract methods (methods with implementation). There are two ways to achieve abstraction in Java: through abstract classes and interfaces.Ībstract classes are classes that cannot be instantiated, meaning they can only be subclassed. By doing so, it provides greater flexibility and modularity in code design. In Java, abstraction is the process of hiding the implementation details of a class and exposing only the functionality to the outside world.
