Yes, I have experience working with functional concepts in Java. Specifically, starting from Java 8, lambda expressions and the Stream API were introduced, which allow writing code in a functional style.

For example, you can use lambdas to process collections:

List<String> names = Arrays.asList("Anna", "Bob", "Charlie");

// Filtering and transforming a list using the Stream API
List<String> filtered = names.stream()
    .filter(name -> name.startsWith("A"))
    .map(String::toUpperCase)
    .collect(Collectors.toList());

System.out.println(filtered); // [ANNA]

Higher-order functions, immutability of data, and the absence of side effects are also applied, which improve code readability and testability.
