Create a login screen for a program. Your program will authenticate a user and tell them if their login is accepted or not. Your program should be able to accept multiple users from a Text File. There is a JPasswordField you could use for the password. If you wish, you may use a JPasswordField...
JPasswordField txtPassword = new JPasswordField( );
The JPasswordField functions just like a JTextField only hiding the characters. To get the text from the JPasswordField, you code...
String password = txtPassword.getText();
