Convert table data to a JTable so it can be displayed on a form

Lettis asked

I am trying to create a class which will create a JTable with Column Headings and the data from the table.

I can extract the column headings easily enough with code like:

Using these variables:

        String ColumnNames[];
        Object RowData[][];
        int ColumnCount = 0;
      // First establish how many columns we've been sent
        ColumnCount = theData.getMetaData().getColumnCount();

   // Get the columnNames we were sent
        for(int x=1;x<ColumnCount+1;x++){
          theColumnName = theData.getMetaData().getColumnName(x);}

Where theData is the RecordSet sent to class.

However, I am struggling to extract the data into the object array:

   // Get the Data from the Query
            int y = 1;            
            while(theData.next()) {
                (for int z = 1; z<x;z++){
                 ' RowData is defined as an object array
                 ' Cant get this bit to work no matter what I put
                 RowData[][] = {??????};
        catch(Exception ex){
            // If something went wrong here simply throw an exception back to the
            // calling routine
            throw ex;

If RowData is defined as an Object array like Object RowData[][]; then how do I achieve this part? I won't know how many columns are being sent or how many rows but I need to put the data into an object so I can put the data into a JTable:

         final JTable table = new JTable(RowData, columnNames);

and then return the "table" to the calling routine.

I want to do this as a separate class so that I can reuse as I will be interrogating many tables within my application and I need this class (or something similar) to display the data that's currently in the table they are trying to add a record to.

Any suggestions would be appreciated
