I am after Jtable code that will display the rows and columns of a 2d array called returned array. Can anyone help? I am currently using a for loop within main to populate a variable with the values from the array, which is then displayed via a dialog box.

Cheers

Vector data = new Vector();
Vector cols = new Vector();
// add columns names

for (int i=0; i<array.length; i++)
{
   Vector row = new Vector();
   for (int j=0; j<array[i].length; j++)
   {
      row.add(new Integer(array[i][j]);
   }
   data.add(row);
}
JTable table = new JTable(data, cols);

A Vector class is a (growable) array of objects.

add it to your component hierarchy.
eg. to add it to your dialog you could use:

dialog.getContentPane().add(table);

create a model class extending AbstractTableModel,

place your vectors in there and fill in the code for the getElementAt(int row, int col)

then make your jtable and pass it the new class as its model,

when you call fireStateDataChanged(); in the model this will fill the data for you.
