What are the benefits of using lambda expressions in Java?

Lambda expressions in Java provide a clear and concise way to represent a function interface. They enhance code readability and reduce boilerplate code.

Can you give me an example of how they simplify code?

Sure! Instead of using an anonymous class to implement a functional interface, you can use a lambda expression. For example, instead of writing:

new Thread(new Runnable() {
    public void run() {
        System.out.println("Thread running");
    }
}).start();

You can simply write:

new Thread(() -> System.out.println("Thread running")).start();

Are there any performance benefits as well?

Yes, lambda expressions can improve performance by enabling better optimization by the Java compiler and allowing for more efficient use of resources, especially in parallel processing.

What about their impact on functional programming in Java?

Lambda expressions are a key feature that brings functional programming capabilities to Java, allowing developers to write more expressive and flexible code.
