Sorting ArrayList Objects.

Zone: Java Programming Language

Tags: arraylist, sort

Hi,

Below is the class which sorts the list of strings and integers. I passed the arguments as 115R 1125R 147C 37R 57R 37C and it shows the result as 1125R 115R 147C 37C 37R 57R. But the problem is I want the output as 37C 37R 57R 115R 147C 1125R. Can anyone help me with this. Its really important.

import java.util.*;

public class SortArrayList
{
      public static void main(String s[])
      {
            Collections col;
            List l = sort(s);

            System.out.println("\nStrings sorted List ...");
            for(int i = 0; i < s.length; i++)
            {
                  System.out.println((String)l.get(i));
            }

            int ints[] = {
                                    11, 2, -22, 401, 6
                                    };

            Integer in[] = new Integer[ints.length];
            for(int i = 0; i < in.length; i++)
            {
                  in[i] = new Integer(ints[i]);
            }

            l = sort(in);
            System.out.println("\nIntegers sorted List ...");

            for(int i = 0; i < in.length; i++)
            {
                  System.out.println((Integer)l.get(i));
            }
}

public static List sort(Object o[])
{
            ArrayList al = new ArrayList();
            for(int i = 0; i < o.length; i++)
            al.add(i, o[i]);
            List list = Collections.synchronizedList(al);
            Collections.sort(list);
            return list;
}
}

Thanks.
