How to sort Arraylist in ascending 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);
//After Sorting

System.out.println(al);

}

Output

//Before Sorting

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

//After Sorting

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