Calling another class from a java program

Question

I tried to call the Server1.class from the password program, but I failed. The password program source code is as follows:
class PasswordDialog extends java.awt.Dialog implements java.awt.event.ActionListener
     * Constructor. Create this visual dialog component.
     public PasswordDialog(java.awt.Frame parent, PasswordVerifier verifier)
          super(parent);
          addWindowListener(new WindowEventHandler());
          setLayout(new java.awt.FlowLayout());
          setSize(500, 100);
          this.verifier = verifier;
          add(useridField = new java.awt.TextField(10));
          add(passwordField = new java.awt.TextField(10));
          add(okButton = new java.awt.Button("Submit"));
          add(cancelButton = new java.awt.Button("Cancel"));
          okButton.addActionListener(this);
          cancelButton.addActionListener(this);
          passwordField.setEchoChar('*');
          useridField.requestFocus();
     public void actionPerformed(java.awt.event.ActionEvent e)
          if (e.getSource() == okButton)
               // Invoke password verification callback
               try
                    boolean result = verifier.verifyPassword(
                         useridField.getText(), passwordField.getText());
                    if (! result) return;     // verification failed; don't close this dialog
               catch (Exception ex)
                    ex.printStackTrace();
               // Close this dialog
               System.out.println("I still can't call the Server1 class");
               dispose();
          else if (e.getSource() == cancelButton)
               dispose();
     class WindowEventHandler extends java.awt.event.WindowAdapter
          public void windowClosing(java.awt.event.WindowEvent e)
               System.exit(0);
     // Private objects
     private PasswordVerifier verifier;
     private java.awt.TextField useridField;
     private java.awt.TextField passwordField;
     private java.awt.Button okButton;
     private java.awt.Button cancelButton;
interface PasswordVerifier
     public boolean verifyPassword(String userid, String password) throws Exception;
public class password implements PasswordVerifier
     * Main routine for testing only.
     public static void main(String[] args)
          password verifier = new password();
          java.awt.Frame f = new java.awt.Frame("Password Verifier");
          f.setSize(100, 100);
          f.show();
          PasswordDialog d = new PasswordDialog(f, verifier);
          d.show();
     public boolean verifyPassword(String userid, String password) throws Exception
          return (userid.equals("Albert") && password.equals("Einstein"));
and the Server1.java is as follows:
//Server Application

I tried to create a new object by typing:
Server1 s = new Server1();
then call the main function
new Server1("Server");
but it doesn't work. Anybody can help me with this?

Answer 1

try
Server1 s = new Server1();
s.Server1("Server");
or
new Server1().Server1("Server");
