import java.io.FileWriter;
import java.io.IOException;
import java.util.Arrays;
import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.JTextField;
public class CCG extends JFrame implements ActionListener{
JLabel jl1=new JLabel("35选7",JLabel.LEFT);

boolean saveFlag=false;
CCG(){
super("Lottery");
jtf.addActionListener(this);
jb1.addActionListener(this);
jb2.addActionListener(this);
jl1.setFont(new Font(null,Font.BOLD,20));
jp1.setLayout(new FlowLayout(FlowLayout.LEFT));
jp1.add(jl1);
jp1.setBorder(BorderFactory.createEtchedBorder ());

}
return s;
}
public static void main(String[] args) {
new CCG();
}
}
