    Default 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?
          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);
    			}

    @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
    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 :/
