//Natural sort
Arrays.sort(strings);
for (String str : strings) {
System.out.println(str);
}
System.out.println("----------------");
//Reverse sort
Arrays.sort(strings, new Comparator<String>() {
public int compare(String first, String second) {
return -first.compareTo(second);
//or
//return second.compareTo(first);
}
});
