Having a interface

1  interface IMAPConnector{
2    Store connect(String username, String password);
3    default Store connect(Account a) {
4      return connect(a.getUsername(), a.getPassword());
5    }
6  }

I like to refactor to have only 

1  interface IMAPConnector {
2    Store connect(Account a);
3  }

How tho do that: All implementing classes and interfaces must change the implementing method from connect(String,String) to connect(Account) having two new first lines:

  String username = a.getUsername();
  String password = a.getPassword();

.


What requirements:
The Method connect(String,String) must not be used.
