After Java 8, Java is still primarily an object-oriented programming (OOP) language, but it has acquired several functional programming features. This evolution allows Java developers to write more concise, expressive and parallelized code while still leveraging the robust OOP principles that the language is built upon.
Key Points:
Java as an Object-Oriented Language:
- Java's core still contains OOP principles such as encapsulation, inheritance, and polymorphism which makes it robust.
- Classes and objects still remain fundamental, and all Java applications interacting with classes and object
Introduction of Functional Programming Features:
- Lambda Expressions: It allows to creation of an anonymous function, enabling a more functional style of coding, more on for operations on collections.
- Streams API: It provides functional operations on stream data like a filter, map, reduce, etc, and allows developers to write simpler code.
- Functional Interfaces: Interfaces with a single abstract method, such as
Predicate
,Function
, andConsumer
, enable passing behavior as a parameter, promoting functional paradigms. - Optional: It encourages a functional approach to handle null values and reduce to null check.
Balancing OOP and FP:
- Java is still not abandoned with OPPS rather it will integrate with functional features to enhance productivity and flexibility.
- Developers can choose both OPPS and functional programming to achieve the best style of programming.
in the above, we get to know that Java still working with OPPS features additionally Functional programming is incorporated so that we can achieve good style coding faster.
