How Do You Implement and Use Java Lambdas Efficiently?

Lambdas simplify the code by allowing concise representations of functional interfaces.

Syntax of Lambdas

Lambdas are written as `(parameters) -> {expression or statement}` in Java.

Example Code

            List numbers = Arrays.asList(1, 2, 3);
            numbers.forEach(n -> System.out.println(n));
            

This example shows how to use a lambda for efficient iteration.
