        programmingLanguages.add("C");
        programmingLanguages.add("C++");
        programmingLanguages.add("Java");
        programmingLanguages.add("Kotlin");

        // Remove all the elements that satisfy the given predicate
        programmingLanguages.removeIf(new Predicate < String > () {
            @Override
            public boolean test(String s) {
                return s.startsWith("C");
            }
