Java Code Snippet for String Ascending and Descending Order using Collections

Program Code Snippet:  public void StringSortIgnoreCase(List<String> lst,String fruits[]) {          Collections.addAll(lst, fruits);        System.out.println("Initial List");        for (String s : lst)            System.out.println(s);              Collections.sort(lst);        System.out.println("\nSorted List with case sensitive in Ascending Order");        for (String s : lst)            System.out.println(s);              Collections.sort(lst, Collections.reverseOrder());        System.out.println("\nSorted List with case sensitive in Descending order");        for (String s : lst)            System.out.println(s); ...

Java String Operations: Removing Extra Spaces, Removing Spacial characters and Numbers, Reversing the whole String, Reversing the each string values
