JTable Sorting

Hello, I am making a program for class, and it is a Swing GUI based program and you input a few different things and it puts it into a JTable. One value it puts in the table is a ratio that is calculated from two numbers the user inputs. I need to be able to sort the table by descending ratio values.
Any help would be appreciated,
Thanks

JMenu

Code:

---

// Display All Animals Menu Method
    public void displayall ()
    {
        contentPane = getContentPane ();
        if (infoPane != null)
            contentPane.remove (infoPane);

        infoPane = new JPanel ();
        infoPane.setLayout (new BorderLayout ());

        L1 = new JLabel ("Peel Pet House Animals:", JLabel.CENTER);
        L1.setFont (new Font ("Arial", Font.BOLD, 24));
        infoPane.add (L1, BorderLayout.NORTH);

        L2 = new JLabel ("End of Page", JLabel.CENTER);
        infoPane.add (L2, BorderLayout.SOUTH);

        String [] columnNames = {"Breed", "Category", "Acquisition Price", "Selling Price", "Profit Ratio"};
        table = new JTable (animalData, columnNames);
        JScrollPane scrollPane = new JScrollPane(table);
        infoPane.add (scrollPane, BorderLayout.CENTER);
        contentPane.add (infoPane);
        validate ();
       
     
    }

Website won't let me attach the .zip of the java file, so here's a link to it PeelPetHouse.java

Have you tried a TableRowSorter object?

kind regards,

Jos

I am fairly new to swing, and java actually, and Im not too sure on how to input TableRowSorter into my program. I was also thinking that instead of sorting the table by the value, it will determine the highest to lowest integers and then place them in the table accordingly.

Alternatively show where I would implement the TableRowSorter in my code.

Thanks,

You haven't read the API documentation for that class because it has a few simple examples how to add it to your JTable ...

kind regards,

Jos

Even if that course happens to be free, it's not worth the money you paid for it. You could go through the Oracle Java tutorials instead -- they are free.

Would you want to learn driving in a car you have to hand-crank to start, with a manual choke and timing advancer that you have to keep adjusting according to speed and gradient?

From Java 2 Platform, Standard Edition (J2SE) 1.4.2

J2SE 1.4.2 is in its Java Technology End of Life (EOL) transition period. The EOL transition period began Dec, 11 2006 and will complete October 30th, 2008, when J2SE 1.4.2 will have reached its End of Service Life (EOSL)
