What is your experience with using streams in Java and in what scenarios have you applied them?

In Java, data streams are used for convenient and declarative processing of collections and other data sources.

Experience includes:

• Filtering collections based on specified criteria (filter)
• Transforming elements (map)
• Sorting (sorted)
• Data aggregation (reduce, collect)

For example, in a project, I used streams to process a list of orders: filtering orders by status, transforming them into DTOs, and collecting them into a final list for frontend transmission.

Example:

List<OrderDTO> processedOrders = orders.stream()
    .filter(order -> order.getStatus() == Status.COMPLETED)
    .map(order -> new OrderDTO(order.getId(), order.getTotal()))
    .collect(Collectors.toList());
