E:\java2\Customer.java:60: exception IllegalPasswordException is never thrown in body of corresponding try statement
                                    catch(IllegalPasswordException e)
我的程序是:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class IllegalPasswordException extends Exception
{
public String getMessage()
{
return"Invalid lenght of the password. The customer shoule not be provided ";
}
}
public class Customer extends JApplet  
{
String custName;
String custPassword;
JPanel panelObject;
JLabel labelCustName; 
JLabel labelCustPassword;
JTextField textCustName;  
JPasswordField textCustPassword;
JButton buttonLogin;
void setPassword(String password)
{
custPassword=password;
}
void setPassWord(String password) throws IllegalPasswordException
{
if(password.length()<6||password.length()>10)
    throw new IllegalPasswordException();
    custPassword=password;
}
public void init()
{
      panelObject = (JPanel)getContentPane();
      panelObject.setLayout(new FlowLayout());
          labelCustName = new JLabel("Customer Login Name");
      labelCustPassword = new JLabel("Password");
      textCustName = new JTextField(15);
          textCustPassword = new JPasswordField(15);
          buttonLogin=new JButton("Login");
      panelObject.add(labelCustName);
      panelObject.add(textCustName);
      panelObject.add(labelCustPassword);
      panelObject.add(textCustPassword);
          panelObject.add(buttonLogin);
          LoginAction loginrequest=new LoginAction();
          buttonLogin.addActionListener(loginrequest);
}
      class LoginAction implements ActionListener
      {
       public void actionPerformed(ActionEvent evt)
       {
                   Object obj=evt.getSource();
                  if(obj==buttonLogin)
                    {    String password =  new String(textCustPassword.getPassword()).trim();             
                     try{ 
                      
              setPassword(password);  
              getAppletContext().showStatus("Valid entry for customer password");
                        }
            catch(IllegalPasswordException e)
            {
           //System.out.print(e.getMessage());
              getAppletContext().showStatus(e.getMessage());
            }                                                                  
                    }
          } 
       }}
