Error won't let me access another class(has got me tearing my hair off)

Question

Alright peeps, so basically i have 2 buttons in the mainfraime class. The first button leads to the contestant's page and the second to the voters page. The first button works and directs the user to the PasswordDemo page, but to the hell of me i cant figure out why it refuses to recognize the "Profile" class that its supposed to go to when the user clicks the second button. It keeps on telling me that "The method Profile() is undefined for the type Mainframe". Please help.
Mainframe class:

Answer 1

Profile p = Profile();That says "call a method name 'Profile' that's defined in the current class."
Perhaps what you meant was:
Profile p = new Profile();which says "create a new instance of the Profile class, and invoke its no-arg constructor."
