Tell us about your experience developing and using Java 8 technologies in projects.

In projects, I actively used the capabilities of Java 8, especially lambda expressions and the Stream API for collection processing. This allowed me to significantly simplify and make the code more readable, for example, for filtering and transforming data. I also used Optional to avoid NullPointerException and improve handling of missing values.

Example of using the Stream API:

List<String> names = Arrays.asList("Anna", "Bob", "Charlie", "David");
List<String> filtered = names.stream()
    .filter(name -> name.startsWith("A"))
    .collect(Collectors.toList());

Additionally, I used new default methods in interfaces, which helped extend functionality without breaking existing code.
