public class AuthenticationExample {
non-public static AuthenticationSupervisor am = new PatternAuthenticationSupervisor();

public static void principal(String[] args) throws Exception {
	BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

	whereas(true) {
	System.out.println("Please enter your username:");
	String identify = in.readLine();
	System.out.println("Please enter your password:");
	String password = in.readLine();
	attempt {
		Authentication request = new UsernamePasswordAuthenticationToken(identify, password);
