Java Swing improperly showing up

Question

I am having a problem...I am trying to put components on a panel...and they arent showing up the way I would expect them too.

here is an example...

here is the code:

package UserInterface;
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.*;
/**

public class FlightPrice extends JPanel {
    private JPanel buttonPane;
    private JPanel dataPane;
    private JLabel outbound;
    private JLabel outDate;
    private JTable departFlights;
    private JLabel inbound;
    private JLabel inDate;
    private JTable returnFlights;
    private JLabel flightCost;
    private JTable priceTable;
    private JButton purchase;
    private JButton goBack;
    private JButton cancel;

     public FlightPrice()
    {
        initComponents();
    }

    private void initComponents()
    {
        BorderLayout borderLayout = new BorderLayout();
        //iniyliazing the componenets\\
        Object[][] data1 =  {{"239", "United", "8:00 AM MCO", "9:05 AM ATL", "767", "25F"}};    
        String[]  name = {"", "",}; 
        Object [][] data2 = {{"612", "United", "4:35 PM ATL", "5:45 PM MCO", "A320", "19A"}};
        String [] name2 = {"",""};
        Object [][] data3 = {{"Adult", "1", "546.00", "56.00", "602.00"}};
        String [] name3 = {"",""};

        buttonPane = new JPanel();
        dataPane = new JPanel(new GridBagLayout());
        outbound = new JLabel("Depart: Orlando TO Atlanta");
        outDate = new JLabel("Date: March 1, 2014");
        departFlights = new JTable(data1, name);
        inbound = new JLabel("Return: Atlanta TO Orlando");
        inDate = new JLabel("Date: March 19, 2014");
        returnFlights = new JTable(data2, name2);
        flightCost = new JLabel("Air Fare Cost");
        priceTable = new JTable(data3, name3);
        purchase = new JButton("Purchase");
        goBack = new JButton("goBack");
        cancel = new JButton("Cancel");

        //adds componetns to the panel\\

        GridBagConstraints c = new GridBagConstraints();
        //adding info into the tables\\
        c.fill = GridBagConstraints.HORIZONTAL;

        c.gridx = 0;
        c.gridx = 0;
        dataPane.add(outbound, c);
        c.gridx = 0;
        c.gridy = 1;
        dataPane.add(outDate, c);
        c.gridx = 0;
        c.gridy = 2;
        dataPane.add(departFlights,c);
        c.gridx = 0;
        c.gridy = 3;
        dataPane.add(inbound, c);
        c.gridx = 0;
        c.gridy = 4;
        dataPane.add(inDate, c);
        c.gridx = 0;
        c.gridy = 5;
        dataPane.add(returnFlights, c);
        c.gridx = 0;
        c.gridy = 6;
        dataPane.add(flightCost, c);
        c.gridx = 0;
        c.gridy = 7;
        dataPane.add(flightCost, c);

        // adding components to buttonPane\\
        buttonPane.add(goBack);
        buttonPane.add(purchase);
        buttonPane.add(cancel);


        //adding panels to the JFrame\\
        add(dataPane);
        add(buttonPane, BorderLayout.SOUTH);

}
}

this is a class that displays extends JPanel. It hold all the components added to the dataPane. The dataPane is then added to the main pane. help?

what it is suppose to look like:

Answer 1

You say BorderLayout borderLayout = new BorderLayout(); but you never pass that layout to a panel using something like this.setLayout(borderLayout) .

In addition, when you add(dataPane) , I recommend that you should specify where, since you intend to use a BorderLayout. Even though CENTER is the default, I recommend saying, add(dataPane, BorderLayout.CENTER) .
