import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.Border;
publicclass makeup{
publicstaticvoid main(String args[]){
String title = (args.length == 0 ?"CheckBox Sample" : args[0]);
JFrame frame =new JFrame(title);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel =new JPanel(new GridLayout(0, 1));
Border border = BorderFactory.createTitledBorder("Sub Toppings");
panel.setBorder(border);
JCheckBox check =new JCheckBox("Anchovies");
panel.add(check);
check =new JCheckBox("Garlic");
panel.add(check);
check =new JCheckBox("Onions");
panel.add(check);
check =new JCheckBox("Pepperoni");
panel.add(check);
check =new JCheckBox("Spinach");
panel.add(check);
JButton button =new JButton("Submit");
Container contentPane = frame.getContentPane();
contentPane.add(panel, BorderLayout.CENTER);
contentPane.add(button, BorderLayout.SOUTH);
frame.setSize(300, 200);
frame.setVisible(true);
}
