hello, im doing a project on email account which must include at least 2 constructors, a finaliser, a display method(), a menu that allows to test all fuctions of the class and a main()
i got the attributes of email : address, password, currentName, noOfmails
and the methods are logine(), inputPassword(), validateUser(), changePassword(), validate(), receiveMail(), deleteMail(), deleteAllMail()
My program is as follows, pls do check
//project: email account
