Kuidas nimetatakse liidest, mida kasutatakse filtritingimuste edastamiseks funktsionaalses stiilis?

In Java, to pass filtering conditions in a functional style, the Predicate<T> interface is used. It represents a function that takes an object of type T and returns a boolean value (true or false), indicating whether the object satisfies the filtering condition.

Example of usage with list filtering:

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

System.out.println(filtered); // Outputs: [Anna]

The Predicate interface is often used in the Stream API to implement collection filtering.
