package my;
import java.awt.GridBagLayout;
import javax.swing.JComboBox;
import javax.swing.JOptionPane;

JPanel panel = new JPanel(new GridBagLayout());
Object[] sports = { "Football", "Cricket", "Squash", "Baseball", "Fencing", "Volleyball", "Basketball" };
JComboBox comboBox = new JComboBox(sports); comboBox.setSelectedIndex(1);
