  }How do i merge these two together so that a catalogItem is created by connecting to the database and uses the select statement?? If any one can help me here i would be really grateful as i am having real trouble with this.

Answer 1

Below is what i have come up with (I cut out the code that just gets in the way for this post, eg the connect to database and import statements) My problem is this would only work once has i need to add the item to the array addedItem in the first for loop, can anybody help me with this has i have tried a number of ways but can't get it to compile.
private static CatalogItem[] addedItem
private static CatalogItem[] ItemsInCat;
CatalogItem item;
CatalogItem details;
        int recordingidDB;
     String directorDB;
     String titleDB;
     String categoryDB;
     String imageDB;
     int durationDB;
     String ratingDB;
     String yearDB;
     float priceDB;
     int StockDB;
// Create select statement and execute it
     try{
         String selectSQL = "select title, director, rating, year_released, price, stock_count, image_name "+
                            "from video_recordings " + "'";
         Statement stmt = conn.createStatement();
         ResultSet rs1 = stmt.executeQuery(selectSQL);
         while(rs1.next()){
          recordingidDB = rs1.getInt("recording_id");
          directorDB = rs1.getString("director");
          titleDB = rs1.getString("title");
          categoryDB = rs1.getString("category");
          imageDB = rs1.getString("image_name");
          durationDB = rs1.getInt("duration");
          ratingDB = rs1.getString("rating");
          yearDB = rs1.getString("year_released");
          priceDB = rs1.getFloat("price");
          stockDB = rs1.getInt("stock_count");
           item =
           new CatalogItem
              (recordingidDB, directorDB,titleDB, categoryDB, imageDB, durationDB, ratingDB, yearDB, priceDB, stockDB);
     String title = "Catalog Items";
out.println(ServletUtilities.headWithTitle(title) +
                "<BODY BGCOLOR=\"#a00e0e\">\n" +
              "<center><img src=\"http://localhost:8080/examples/img.jpg\" width=350 height=200/></center>\n" +
                "<H1 ALIGN=\"CENTER\">" + title + "</H1>\n");
     // loop to go over each item in the array of catalogItem
         for  (int i=0; i < ItemsInCat.length; i++) {
           out.println("__________________________");
           details = item;
     if (details == null) {
out.println("SORRY THERE HAS BEEN AN ERROR ");
     } else {       
addedItem[] // needd to store item in array here
     out.println(titleDB + "\n" + priceDB + "\n");
     out.println("</BODY></HTML>");
     public static CatalogItem getItem(int recordingidDB) {
     CatalogItem item;
for(int i=0; i<itemsInCat.length; i++) {
item = itemsInCat[i];
if (recordingidDB.equals(item.getItemID())) {
return(item);
return(null);
// Close the stament and database connection
