import java.util.ArrayList;

import java.util.Collections;

import java.util.Comparator;

import java.util.List;

public class SortingForList {

public static void main(String[] args){

List<String> fruits = new ArrayList<String>();

fruits.add("Pineapple");

fruits.add("1");

fruits.add("3");

fruits.add("2");

fruits.add("9");

fruits.add("apple");

fruits.add("apricot");

fruits.add("Banana");

fruits.add("mango");

fruits.add("melon");        

fruits.add("peach");

    Collections.sort(fruits);

System.out.println("System generated sorting order::" + fruits);

Collections.sort(fruits, new Comparator<String>() {

   public int compare(String o1, String o2) {              

       return o1.compareToIgnoreCase(o2);

   }

});

System.out.println("Customized sorting order:::" + fruits);

}

}

Out put:

================
