public static boolean isSorted(List<String> listOfStrings) { return Comparators.isInOrder(listOfStrings, Comparator.<String> naturalOrder()); } As we can see, in the above example, we’ve used the natural ordering to check for a sorted list. We can also use aComparatorto customize the sor...

To check whether a List contains a given element or not, you can simply use the List.contains() method as demonstrated below: 1 2 3 4 5 6 7 8 9 10 11 12 13 import java.util.Arrays; import java.util.List; class Main { public static void main(String[] args) { List<Integer> ...
