       public class ArrayFormat {
        static float productPrice[];
        static int productId[];
        static String productName[];
        static String productType[];
        /**
        * @param args the command line arguments
        */
        public static void main(String[] args) {

         productId = new int[]
                  {1001,1002,1003,1004,1005,1006,1007,1008,1009,1010};

         for (int i=0; i<10; i++){
           System.out.format("%5d", i);
            System.out.println("\t"+productId[i]+"\t"+productName[i]
         +"\t"+productType[i]+"\t"+productPrice[i]);
            }
