What are some examples of functional programming in Java?

Functional programming in Java includes using lambda expressions, streams, and method references. Would you like to know more about any specific example?

Can you explain lambda expressions?

Sure! Lambda expressions allow you to create anonymous functions in Java. They enable you to write more concise and readable code, especially when working with collections.

How do I use streams in Java?

You can use streams to process sequences of elements, such as collections. For example, you can filter, map, and reduce data in a functional style.

Can you give me a code example of using streams?

Absolutely! Here's a simple example: List<String> names = Arrays.asList("Alice", "Bob", "Charlie"); List<String> filteredNames = names.stream().filter(name -> name.startsWith("A")).collect(Collectors.toList()); This filters names starting with 'A'.
