When running your project initially, ask the user to enter a password, then call method verify that takes a password as String and check whether the user is allowed to enter the system or not. If the password is accepted, return true to your main program then display the above menu and wait for the user's choice. Otherwise, return false to print an error message and exit the system. N.B.: An accepted password must be of 8 digits and must include at least: 1 Uppercase letter ✓ 1 Lowercase letter ✓ 1 Numeric value (ex: 1 or 5 or 9...) After displaying the Main Menu, If the user selects Por p: Your program should ask the user to enter his/her full name. N.B.: Return to the main menu when the user's name is entered.
