Have you used lambda functions in your projects?

Yes, in Java projects I have used the functional capabilities of Lambda expressions, which have been available since Java 8. Lambdas allow writing more concise and readable code, especially when working with collections and functional interfaces.

An example of using Lambda for sorting a list of strings by length:

List<String> names = Arrays.asList("Anna", "John", "Alexander", "Kate");
names.sort((a, b) -> a.length() - b.length());
System.out.println(names); // [Anna, John, Kate, Alexander]

Lambda expressions simplify passing behavior (functions) as parameters, which improves expressiveness and reduces boilerplate code.
