Hi clecer people!

I am new can i have a little help here please.
I wanted to mcuh the name and password of employee,
entering and exiting the building

( it works but not completely)

The task

Implement a system that restricts which members of staff that have access to
a secure building. Only authorized employees are allowed entry to the
building. Each employee will consists of at least a user name (which is
unique) and a password. he software should allow for, amongst other things:
addEmployee
accepts a name and password, and adds this pair to the collection of
authorized personnel.
removeEmployee
removes a specified employee from the list of authorized employees,
providing that that person is not currently inside the building.
enter
accepts a name and password;
if these details match an entry in the authorized list, then the
individual is granted entry to the building;
if the details are incorrect an alarm is signalled.
leave
accepts a name of an employee;
if this individual is currently recorded as being inside the building they
are allowed to depart;
if the employee is not inside the building an alarm is signalled.
