Arraylist

[kyosugi]

I am doing a micro video application and am experiencing problems with my arraylist. I have 2 separate frame. One is ListGameFrame and the other ListVideoFrame. When I add new games to the ListGameFrame and selects the ListGame option to view, I will also see my items from the videos section. This is my coding for the ListGameFrame for adding games.

public void addGamesToList(ArrayList<Item> items)
{
// Clear any existing rows from the table
this.clearDataFromTable();

    // For each game in the arraylist, add a row to table
    for (Item i : items)
    {
        String GameID = i.getItemId();
        String GameName = i.getTitle();


        String\[\] rowData = {GameID,GameName};
        ((DefaultTableModel)tblGames.getModel()).addRow(rowData);
    }
}

And this my coding for viewing the list of games via a class call VideoManager.

private static void readGameObjects()
{
// Create an ObjectInputStream to read data (from game file)
ObjectInputStream in = openObjectInputFile(gameFileName);
if (in == null) // Nothing to read
return;

    try {
        Item i = (Item)in.readObject();

        // While there are game objects to read...
        while (i != null)
        {
            // Add object to game arraylist
            items.add(i);
            i = (Item)in.readObject();
        }
    } catch (EOFException e) {} // Do nothing if EOF reached
    catch (IOException e)
    {
        System.out.println(e.getMessage());
        e.printStackTrace();
        System.out.println("Error in reading customer file");

    } catch (ClassNotFoundException e)
    {
        System.out.println(e.getMessage());
        e.printStackTrace();
        System.out.println("Error in file format: Customer file");
    } finally
    {
        try {
                // Close the file
                in.close();
        } catch (IOException e)
        {
            System.out.println(e.getMessage());
            e.printStackTrace();
        }
    }
}

Sorry for the long codes as I do not know how to simplfy the problem I am facing now. May I know if there is any specific problems in my coding which results the game list to also show the video list?

I dont think anybody's going to help you in that code. You should try Sun Developer's Network (SDN).

In all honesty, there is not a lot of information given here, as I don't exactly know what you are trying to do. Are you simply listing the data and adding/removing from it?

Can you clarify what you mean by this please. Do you mean on the UI (ie. mistakenly added to it) or actually in the List variable? In which case, debug your code and have a look at where the List is generated/output and see why it is being added. ps.

}
} catch (EOFException e) {} // Do nothing if EOF reached

Simplified can be:

Item i;
while ((i = (Item)in.readObject()) != null)
items.add(i);

If at first you don't succeed, you're not Chuck Norris.

What are you playing at? If you don't understand it, because of your abundant lack of knowledge, then don't answer it with pure dribble.

Rajdeep, You are stupid. Your answers are, at best, wrong and often plain misleading. Please, you obviously have no knowledge of java so don't damage other people's future by poluting their brains with this rubbish. Stop. Desist. Go away.

Welcome to the seventh sphere of hell that Rajdeep.Net brings along to whatever forum he trolls. So far he worked his way through VB.Net, C# and C++ forums with his idiocy and most often stupid, deceiving posts which he admitted where malicious with intent to hijack and/or harm other peoples property. His posts should be ignored and disregarded, and marked as abusive as his answers are almost always are incorrect and misleading.
