Steps to Reproduce:
In User.java, run the function login() and changePwd(), we can see the return results of if conditional sentences.

Expected output:
When method iUserDAO.queryUser() or iUserDAO.changePwd() is true, it will return a new constructor, otherwise it will return null.

Actual output:
It only can return new constructor when if conditional sentences are true.

Resolution:	
We should add a branch to return null in the Login() and changePwd() in the if conditional sentences.
