Print array to table

Question

I need to print two arrays in a table, i.e. each array represents another column in the table.
I currently have this which outputs the results of each array but not in table format:
String[] FN = (String[])setFN.toArray(new String[setFN.size()]);
               String[] SerialArray = (String[])setSerial.toArray(new String[setSerial.size()]);
               StringBuilder FNbuilder = new StringBuilder(FN.length);
               for (int i=0;i<FN.length;FNbuilder.append(FN[i++])) FNbuilder.append("\n");
               for (int i=0;i<SerialArray.length;FNbuilder.append(SerialArray[i++])) FNbuilder.append("\n");
               JOptionPane.showMessageDialog(null, FNbuilder.toString(), "Printing results", JOptionPane.INFORMATION_MESSAGE);I hoped it would be as easy as this, but its not! -
JTable jTable1 = new JTable (FN);
String [] columnNames = {"Serial Number", "Friendly Name"};
Object [][]data = {
     {SerialArray},{FN}
JTable jTable1 = new JTable (data, columnNames);Any advice would be greatly appreciated.
Thanks!

Answer 1

Those sort of parallel arrays are generally a bad idea. I call that code smell "object denial".
Anyway, you have several options.
1. Copy the data over to a Object[][] where the data is orgainized by row, not column.
2. Define an object that holds a serial number and a friendly name, call it Product, or whatever it should be. Instead of having separate arrays have a single:
List<Product>
subclass AbstractTableModel to draw its data from a List<Product>. Done!
