how to sort a list in java

Comment

List<String> elements = new ArrayList<>();
// The list of strings will be sorted lexicographically
elements.sort();
// You can also implement a custom comparator
Comparator<String> comp = new Comparator<String>(){
   @Override
   public int compare(final String s1,String s2) {
     //TODO return 1 if rhs should be before lhs 
     //     return -1 if lhs should be before rhs
     //     return 0 otherwise (meaning the order stays the same)
     }
 };
elements.sort(comp);
