public static void main(String[] args) { List<String> strings = Arrays.asList(“a”, “b”, “c”, “d”); strings.stream() .filter(s -> test(s, “temp”)) .map(s -> transform(s, “temp”)) .count(); } public static boolean test(String s1, String s2) { return s1.equals(s2); } public static String transform(String s1, String s2) { return s1 + s2; } Considering the code given above, I am […]
