What are the best practices for Java 8 programming?

Some best practices for Java 8 include using streams for collections, leveraging lambda expressions, and utilizing Optional to avoid nulls.

Can you explain how to use streams effectively?

Sure! Streams allow you to process sequences of elements, enabling operations like filtering, mapping, and reducing in a functional style.

What is the purpose of the Optional class?

The Optional class is used to represent a value that may or may not be present, helping to avoid NullPointerExceptions.

Are there any performance considerations with using streams?

Yes, while streams can improve code readability, they may introduce overhead. It's important to use them judiciously, especially in performance-critical sections.

Can you give an example of a lambda expression?

Certainly! A simple lambda expression could be (x, y) -> x + y, which adds two numbers together.
