Hello, I was assigned this problem for an Initial Project and need help finding out where to start, as I have not taken Java in over a year. Thanks

Think about a dormitory that has a secure keyless entry system. Inside its entrance hall, there is an entry system (case sensitive) where the dorm residents must enter their name, room number, and password. Upon entry of valid data, the system will unlock the inner door that leads to the dorm's living quarters.

Your task is to implement a sentry program that asks for three pieces of information: resident's name, room number, and a password. A password is any sequence of characters that are at least three characters long. If everything matches, then the system unlocks the door so the resident can enter. As soon as the validated resident enters, the door is locked again. We will assume that no two residents have the same name.
