Can I use Java for functional programming?

So far Java was supporting the imperative style of programming and object-oriented style of programming. The next big thing what java has been added is that Java has started supporting the functional style of programming with its Java 8 release.

What is functional style programming in Java?

Functional programming is a programming style in which computations are codified as functional programming functions. These are mathematical function-like constructs (e.g., lambda functions) that are evaluated in expression contexts.

How is functional programming implemented in Java?

Functional programming, being a subset of declarative programming, offers several constructs like higher-order functions, function composition, and function chaining. Think of the benefits that Stream API has brought into Java 8 for handling data manipulations.
