How to sort Arraylist in Descending order

Eg:

public static void main(String[]args){

//creation of Arraylist  with string arguments

//adding elements to Arraylist 

ArrayList<String> al=new ArrayList<String>();

al.add("India");

al.add("US");

al.add("Australia");

al.add("Germany");

al.add("Europe");

//Before Sorting

System.out.println(al);

//Sort Statement

Collections.sort(al,Collections.reverseOrder());

//After Sorting

Collections.sort(al);

}

Output:

//Before Sorting

[India,US,Australia,Germany,Europe]

//After Sorting

Output:[US,India,Germany,Europe,Australia]
