Java simple login function not working

Hello there :)
i have this simple login function where i compare what you write with what is in the array and if it is the same it will open a new window else nothing will happen but it doesn't seem to work :/
can someone please help me what is wrong with my code?

Code :

---

      login.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
		String[] usernameArray={"User1","User2","User3"}; 	//array where i save file username and a other one for password
      String[] passwordArray={"Pass1","Pass2","Pass3"};
 
			for (int i=0; i<usernameArray.length; i++){							// make a for loop so it tjeks all the different users
			if((usernameField.equals(usernameArray[i]) && passwordField.equals(passwordArray[i]))){
				JOptionPane.showMessageDialog(null,"Welcome "+usernameField+"\n"+"You are logged in");
				login.addActionListener(new login());
				dialog.setVisible(false);
            frame.setVisible(false);
			}
 
         }															// end of for loop 
      }
		});

Mind telling me how?


@vigneshwaran: You need to read about what addActionListener does. You are no where calling the new GUI to display.

don't i do that with

Code :

---

login.addActionListener(new login());

---

or is that just me that is wrong? because i can make it work if i take it out of the login method there then it works butn when i put it in the login method it doesn't wanna open the new window or anything :/
