Answer:

 List<Integer> numbers = Arrays.asList(1, 3, 8, 23, 28, 1, 2);

 int num = numbers.stream().sorted(Comparator.reverseOrder()).skip(1).findFirst().orElse(null);
 
 //Other ways
 int num3 = numbers.stream().sorted(Comparator.reverseOrder())
                            .limit(2)
                            .reduce((first, second)->second)
                            .orElse(null);
System.out.println("Num3:"+ num3);
