Implement a class LoginForm that simulates a login form that you find on many web
pages. Supply methods
public void input(String text)
public void click(String button)
public boolean loggedIn()
The first input is the user name, the second input is the password. The click method can be called with arguments "Submit" and "Reset". Once a user has been successfully logged in, by supplying the user name, password, and clicking on the submit button, the loggedIn method returns true and further input has no effect. When a user tries to log in with an invalid user name and password, the form is reset. Supply a constructor with the expected user name and password.
