Dear Java Friends,

The following snippet code is for storing the ArrayList values into Object array and it has to display using another loop. My requirement is I want to store only in Object[] array but not in any other data type. Its compiling but giving run time error in the following line. Can anybody give their suggestion   or recode the below.

lo_oName = (Object[ ]) lo_arrListName.get(i); //giving error here in runtime.

/* FullCode */

import java.util.*;

public class Generic   {

 public static void main ( String args[ ]  )   {

  Object lo_oName[] = null;
  ArrayList lo_arrListName = new ArrayList();
  lo_arrListName.add("HAPPY BIRTHDAY TO YOU...............");
  lo_arrListName.add("YOU ARE NOT YOU YOU ARE HE...............");
  lo_arrListName.add("THE GOD...............");
  lo_arrListName.add("PRAY HIM DEEPLY PEACEFULLY...............");
  lo_arrListName.add("HE GIVES ALL TO YOU..............."); 
  
  /*lo_arrListName.add(new Integer(100));
  lo_arrListName.add(new Integer(200));
  lo_arrListName.add(new Integer(300)); */
     
   int i = 0;
   System.out.println ( lo_arrListName.size());
   while (i  <  lo_arrListName.size() )
   {      
   System.out.println ( "In the while loop........." );
   lo_oName = (Object[ ]) lo_arrListName.get(i);
   System.out.println ("After storing the arraylist value in Object variable..");
   System.out.println ("Value in object... " + lo_oName[i].toString() );
   i++;
   }
  
  }
}
