Can you give me some examples of Java streams?

Can you give me some examples of Java streams?

Sure! Java streams are a powerful way to process sequences of elements. For example, you can use streams to filter a list of integers to find even numbers.

How do I create a stream from a list?

You can create a stream from a list using the stream() method. For example: List<Integer> numbers = Arrays.asList(1, 2, 3, 4); Stream<Integer> stream = numbers.stream();

What are some common operations I can perform on streams?

Common operations include filter(), map(), reduce(), and collect(). Each of these allows you to manipulate the data in different ways.

Can you show me an example of using filter()?

Absolutely! Here's an example: List<Integer> evenNumbers = numbers.stream().filter(n -> n % 2 == 0).collect(Collectors.toList()); This will give you a list of even numbers.
