Streams in Java

 Streams in Java

Streams are a way to process collections of data in a declarative way. They allow you to filter, transform, and aggregate data using a functional programming style.

Example code:

python

List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5);

int sum = numbers.stream()

                .filter(n -> n % 2 == 0)

                .mapToInt(Integer::intValue)

                .sum();

System.out.println("Sum of even numbers: " + sum);
