Suggested change

	public static String getUserEmail(int id) {
	return users[id].getEmail();
	}
	public static String getUserPassword(int id) {
	return users[id].getPassword();

It's better to create UserService class-level variable
find user by email by using findByEmail()
check password and user not null

[Elena-Bruyako]

it should be class-level variable (not method)
in this case - you create userService object each time you call login method
Wrong name of variable

Suggested change

	UserService user = new UserService();
	UserService userService = new UserService();

[Elena-Bruyako]

create local variable for user, that you find by email and implement HW

[Elena-Bruyako]

Suggested change

	User foundUser = userService.findByEmail(email);
	return foundUser != null
	&& foundUser.getEmail().equals(email)
	&& foundUser.getPassword().equals(password);
	User user = userService.findByEmail(email);
	return user != null && user.getPassword().equals(password);
