Java Abstraction is a mechanism of hiding the implementation details and showing only the necessary information to the user. It can be achieved through abstract classes and interfaces.

Abstract classes cannot be instantiated and are used as a base class for other classes. Interfaces define a contract that must be implemented by the implementing classes. Abstraction helps in achieving encapsulation and modularity in code, making it easier to maintain and modify. It also helps in achieving a higher level of security in code by restricting access to sensitive information.
