The method getPasswordAuthentication takes no parameters and returns an object of
type PasswordAuthentication.
1. String username, password;
Initialized the local variables username and password to type String
2. String result = JOptionPane.showInputDialog("Enter 'username,password'");
This one confuses me a bit because I normally do not deal with Swing classes.
However, it looks like it grabs the username and password entered through the
JOptionPane in the form 'username, password'
3. StringTokenizer st = new StringTokenizer(result, ",");
Using the java class StringTokenizer, extract the username and password which are
delimited by a comma
4. username = st.nextToken();
The first String chunk, which is username, is grabed through the nextToken method
and the local variable username is set to the nextToken's return value
5. password = st.nextToken();
The second String chunk, which is password, is grabed through the nextToken method
and the local variable password set to the nextToken's return value
6. return new PasswordAuthentication(username, password);
An instance of PasswordAuthentication is initialized with the values contained in
username and password. This instance is returned to the calling method.
I suppose you were looking for an explanation of the JOptionPane which is where
this explanation breaks down because I don't know how it works because I don't do
GUIs. My GUESS is that an instance of JOptionPane pops up, the user is expected to
enter a String in the form of 'username, password' and either the 'Enter' key or a
button is pressed by the user on the dialog box and control is returned to the
getPasswordAuthentication method where the information entered is extracted by use
of the showInputDialog method.
