This is the code:
(main method)
import java.text.*;
import javax.swing.*;
public class KhanPassword
{
public static void main (String [] args)
{
KhanAccount oneacct = new KhanAccount ();
inputacct (oneacct);
System.exit(0);
}
public static KhanAccount inputacct (KhanAccount aacct)
{
/* If an invalid password is entered (or the two entries do not match),
the user should be prompted to try again. */
/* Continuously reads a pair of passwords until the two match.*/
do { // Continuously reads the password until it is a valid one.
do {
String password = JOptionPane.showInputDialog("Enter password:\n"
+ "(must be at least six characters long and have at least one digit)");
aacct.setusername(un);
/* display a message indicating whether it is valid or not */
if (!aacct.setPassword(passwd))
JOptionPane.showMessageDialog(null, "Invalid password!");
else {
JOptionPane.showMessageDialog(null, "Valid password!");
break;
}
}
while (true);
/* The password should be prompted for twice */
String reenter = JOptionPane.showInputDialog("Re-enter password:");
/* the entries should match or a message provided to the user. */
if (!passwd.equals(reenter))
JOptionPane.showMessageDialog(null, "Two passwords don't match!");
else
JOptionPane.showMessageDialog(null, "Two passwords match!");
} while (!passwd.equals(reenter));
return aacct;
}
}

public static void KhanAccount (){};
