    Java 8 introduced the Stream API, which provides a functional programming approach to process collections of data. Streams allow operations like filtering, mapping, and reducing data in a declarative manner. Below are some common Java 8 stream-related questions and examples to help you understand its usage.

    What is a Stream in Java 8?

    A Stream is a sequence of elements that supports various methods to perform computations. It does not store data but operates on the source (like collections, arrays, or I/O channels). Streams are lazy, meaning computations are only performed when a terminal operation is invoked.

    Example:

    import java.util.Arrays;
    import java.util.List;

    public class StreamExample {
    public static void main(String[] args) {
    List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5);
    numbers.stream()
    .filter(n -> n % 2 == 0) // Intermediate operation
    .forEach(System.out::println); // Terminal operation
    }
    }

    Output:

    Difference Between map() and flatMap()

    • map() transforms each element of the stream into another form.

    • flatMap() not only transforms but also flattens nested structures into a single stream.
