Adding values from a List to Jtable

Question

Hello my problem is the foloowing i have a List of a certain class of which i want to bind the values to a jtable (order in which they are added isnt important right now) The class that is in the list is as folows

public HighScore(int score, int amountofplayers, String playerName,String dateString) {
    this.score = score;
    this.amountofplayers = amountofplayers;
    this.playerName = playerName;
    this.dateString = dateString;
}

the function that returns the list is

   public ArrayList<HighScore> GetHighScores()
{
    ArrayList<HighScore> highscores = new ArrayList<HighScore>();
    //get highscores from databse

    //insert some test values
    highscores.add(new HighScore(125, 2, "Piet","20-10-2015"));
    highscores.add(new HighScore(167, 2, "Henk", "19-10-2015"));
    highscores.add(new HighScore(278, 2, "Jan", "11-10-2015"));
    return highscores;
}

So now i want to add all these highscores to my Jtable1 in which resides in a jpannel. What would be the easiest/most effiecient way to do this

If you have to create a JTable object, the simplest way is to use one of its constructors.

There are two JTable constructors that directly accept data (SimpleTableDemo uses the first):

JTable(Object[][] rowData, Object[] columnNames)
JTable(Vector rowData, Vector columnNames)

rowData must have your objects in the position you want them to be shown. For instance, to obtain the object in the first column of the second row, JTable will execute rowData[1][0] (it follows the form rowData[row][col]).

You should create a custom TableModel to hold your HighScore objects.

Check out Row Table Model. It will show you how to either:

Create a custom TableModel from scratch
Use a generic TableModel and just implement a couple of methods to reflect the data of your HighScore object.

you should use a DefautTableModel, creating a instance of it. Then use a for loop passing your highscores to an Object[], then adding rows with the DefautTableModel addRow method.
