I have defined an abstract table model but one of the columns should house date values as dd/mm/yyyy format not sure how to do this.

I have a external global file and have hard coded the dates as dd/mm/yyyy.

How can I define this column within my abstract table model so that to only allow only dates having dd/mm/yyyy format.

public class OptraderGlobalParameters
{


   public static boolean DEBUG = true; //Set DEBUG = true for Debugging

   /*=========================*/
   /*Table Array For Dividends*/
   /*=========================*/
   public static String[] columnNames
              = {"Date",
                 "Dividend",
                 "Actual",
                 "Yield (%)"
                };



   public static Object[][] data
    = { {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)},
        {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)},
        {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)},
        {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)},
        {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)},
      };



}
