Question

Create a JApplet that asks a user to enter a password into a JTextField and then to
press Enter. Compare the password to “Rosebud”; if it matches exactly, display “Access
Granted”. If not, display “Access Denied”. Save the file as JPasswordA.java.

Modify the password applet in Exercise 2a to ignore differences in case between the
typed password and “Rosebud”. Save the file as JPasswordB.java.

Modify the password applet in Exercise 2b to compare the password to a list of five
valid passwords: “Rosebud”, “Redrum”, “Jason”, “Surrender”, or “Dorothy”. Save the
file as JPasswordC.java.
