Java Sort list without using Collections.sort() method

import java.util.*;
class SortList 
{
    public static void main(String[] args) 
    {
        ArrayList<String> list=new ArrayList<String>();
        list.add("D");
        list.add("B");
        list.add("A");
        list.add("E");
        list.add("C");

    Object arr[] = list.toArray(); 
    Arrays.sort(arr);
    for(int i=0;i<arr.length;i++){
    System.out.println(arr[i].toString());
     }
    }
}
